K&N Air Filter

The K&N Air Filter is cheapest and easiest upgrade you can do and still expect incredible or, at least, reasonable results. Would you like a general Truck or Car Miles Per Gallon article, or a more basic article but still about a K&N Performance Filter?

First lets discuss the numbers of the K&N Air Filter:

K&N: CFM’s (Cubic Feet per Minute of air moved through a K&N filter): 881, for the round type and 441 for the sandwich type (this being the long and flat filtration)
typical disposable paper filtration CFM’s: 548 for the round and 319 for the sandwich type

Having an air filter that allows more a CFM’s of air is only the beginning. Based on the conditions of which you drive, it’s typical to be able to drive 60,000 miles before you even have to clean your K&N Air Filter. What makes a K&N Air Filter different is that it has a metal screen strengthening a thin, precision made cotton wall against dust and grime. In laboratory tests this doesn't just allow more filtration with less obstruction than standard filtration by companies like Fram or STP, but the K&N Air Filter actually allowed a straighter flow past the filtration medium, which increases the delivered volume, which in turn makes the engine run cooler. Some vehicles get 8 more horse power, which if you're not too lead footed, will directly turn into less fuel consumption and better trucks or cars miles per gallon.

How does a K&N Air Filter really work?

For the most performance it is important for every surface that air passes over to be polished to allow for the straightest, least ruffled flow, which allows for a higher volume of CFM’s to get through the filtration medium. This is the reason cold atmospheric intakes are popular, it isn't just that colder atmosphere mixes with gas better, it's the fact that they're smooth and polished, which is just like a polished vehicle having less friction or tug against moving forward.

The smaller the engine the higher the demand on air because of the frequently lower compression ration of 8:1 instead of the standard V6 12:1. Typically, due to this basic engineering principle it’d make sense that a K&N Air Filter would do even more for a 4 cylinder, but the reality is that at least on one V6 sedan I’ve seen the gas mileage, miles per gallon, or fuel mileage, which ever you want to call it, go up just as much as that of a four cylinder’s engine, depending on your numbers perspective.

Consider this perspective while reading results from K&N Air Filters that AutoBravado has personally seen by comparing a V6 Ford Taurus versus a 4 cylinder Ford Escort and Chevrolet Prizm:
Notice a percentage versus a number increase in your truck’s or car’s miles per gallon. If you’ve gone from 20 to 24 in your truck's or car's miles per gallon you’ve increased the number by 4 but your increase in fuel mileage is 20 percent. In the mean time, if you see the same number of miles per gallon going up on a four cylinder, like from 33 to 37 then you may be seeing the increase by 4 but you’re actually seeing a 12.1 percent increase on the 4 cylinder versus a better 20 percent increase on the 6 cylinder. Auto Bravado has promised that the physics or math would be taken care of for you, but I think this concept is important if you’re going to understand what the better results mean when you’ve received better fuel mileage by installing your K&N Air Filter.

If you monitor your car’s or truck’s miles per gallon carefully it’s is highly unlikely, in Auto Bravado’s experience, that you’ll find yourself disappointed with this upgrade. For a personal experience on the K&N Performance Filter, read Auto Bravado’s other article by clicking on this link.

Remember AutoBravado's goal: The Cars or Trucks Miles per Gallon: We all want better numbers, but do we really know how to get them? Let us learn that to get results is to have fun! There are tricks that it took many mechanics decades of experience to figure out and perfect. The truck’s or car’s miles per gallon of the vehicle you own relies on more factors than most mechanics even know about. It is AutoBravado's commitment to stay ahead of the discoveries and keep you well informed. It is a basic concept of physics. If the engine is singing the sweet song of being tuned and other factors are in place, it will, by the laws of physics, require less fuel to get the same results. Contact Auto Bravado:

The K&N Performance Filter

I've had an engine that didn't just want it, but needed it. AutoBravado's favorite and most accessible way to get the air you need to make your car be at it's best is to make use of K&N filtration technology, an incredible high performance filter for the air going into your car. I had been doing upgrades on one car years gone by and it tended to run a little hotter. I thought that that was okay, I mean I was getting more performance right? Well, wrong. One day, merrily driving up a violently angled hill on the way to a religious service, the engine's heat kept getting hotter and hotter still until I realized that if I shut my motor off and the radiator fluid stopped going through the engine that I'd be looking at some engine damage. I decided to leave the transmission in gear and go down the hill letting the tachometer read at a higher RPM, which would allow for a maximized radiator fluid amount to get through the block. The gauge kept reading hotter!

At this point I realized the engine was so hot that the radiator temperature was only catching up with the actual temperature that you see by the gauge. The thought popped in my head that when a week ago I was considering better air filtration and I should have bought that K&N Performance Filter, more air, less heat.

So, wishing I knew then what I know now (You can leave an engine in gear and drive going down hill in a manual transmission with the engine off so that no more combustion occurs, causing no more extra heat, and allow the radiator and motion of the vehicle to cool the engine.), I in exasperation gave up and shut down cut of the ignition and waited until it was cool enough to drive again. I checked this by putting my hands over the engine compartment and waiting until the motor was touchable. I couldn't help but wonder if something in the radiator system/cooling system had broken or my the installed upgrades were just too much. That particular day I had a tougher load: my heaviest friend at the time, 350 lbs. or more and his light wife coming with us.

Within a week I had installed my K&N High Performance Filter for better air filtration. In one more week - having noticed my coolant gauges running much cooler and the engine was running much smoother since it was getting it's air intake needs met - I set off up the same hill seeking the same religious experience for me and a challenge for my upgraded car. For a K&N Performance Filter really is an upgrade, people don’t realize that it isn’t just the super chargers or modified transmission’s that are upgrades, it’s the little stuff. I wasn't able to get the overweight friend or his wife to come to tax the small engine as I had before - they were too afraid to come! So I did the best I could to test my K&N performance filter by throwing all of my tools into the back and taking my beautiful wife with me, which caused her upset when she realized she was being a part of an experiment! So, still being 100 to 200 lbs. short of my last experience, I decided to do my best with the little motor to race up the hill and not take it easy. The car not only dug in with its K&N performance filter but it ran cooler going up that hill than it did in every day life! That filtration technology upgrade made the car desire a higher RPM . . . okay, okay it was probably just me that craved the higher RPM’s, but I was able to get away with the higher RPM without as many consequences!

The K&N performance filter is not available in all shapes and sizes for every vehicle unless you are willing to upgrade to a cold air intake. For example: my new car won’t let me go to town on this one like my old one did. That is why a cold air intake is necessary for people who happen to have cars like the both of us, which have limited K&N performance filter availability. Auto Bravado has a wonderful link for cold air and polished intakes on the Weapon R Dragon Cold Air Intake page. Don't just want a personal experience and you want techinical details too? See Auto Bravado's other article: K&N Air Filter.

(Note, after months of searching, I now have a custom K&N performance filter for that newer car, which no one else had and I included the link below.)

Have you ever had your engine over heat after an upgrade? The K&N 33-2945 High Performance Replacement Air Filter will get more of that cooling air to get into and help your engines needs. This also allows for more stronger, straighter air flow at any RPM. Click on this link, put in your vehicle specifics and find your way to better filtration technology.

Truck's or Car's Miles Per Gallon

We all want better numbers, but do we really know how to get them? Did you know that when the engine is more efficient that it delivers more power?Let us learn that to get results is to have fun! There are tricks that it took many mechanics decades of experience to figure out and perfect.The truck's or car’s miles per gallon and the tuning of an engine:

The first, simplest, and most economical place you can start with to improve the car’s miles per gallon is in the spark plug wires pages, but keep digging further! That means that when more gas is put into the engine, large or small, the engine will take advantage of that fuel better and translate into more power. Look for the simple ideas article: it explains the jalopy as "The Great American Jalopy" that have been forgotten by most since the 70’s. You’d be amazed, whatever your vehicle may be, how new or old, how these simple ideas will improve your vehicle into having that achievable, great car’s miles per gallon!

Don’t quit now there is even more valuable information coming:

The car's or truck's miles per gallon and the transmission cooler:

A car’s miles per gallon is also dependent on transmission coolers to keep wear and tear away from the transmission. If you don’t let the transmission lose its power in age, then the transmission won’t be dragging down the vehicle’s mileage, which would rob power and efficiency from the vehicle. Speaking of which, when was the last time you changed your transmission fluid and filter? It’s like the nectar of the God’s when it’s new, and when it’s old it smells burnt and worn out. It’s simple and it improves the car’s miles per gallon!

The car’s or truck's miles per gallon and the common misunderstanding: Efficiency is power, and power is efficiency, as long as it’s not based on forcing more fuel into the engine.
Do you now see the relationship between the car’s miles per gallon to power and efficiency? It can‘t be emphasized enough that when there’s more efficiency, there’s more power. If you came to this website for power, you‘ll still learn here; if you came to take control of your pocket book at the pump, you also came to the right place. Your car’s miles per gallon is in good hands with the knowledge based off of many great men’s and women’s collected wisdom.

The car’s or truck's miles per gallon and its major robber or advocate:
It is amazing how many vehicles can be found missing something so basic as a proper spark plug gap, or good spark plug wires. Is your truck‘s or cars miles per gallon missing out? Don’t forget that extra power comes with an adrenaline rush. There is an undeniable feeling of driving excitement. It is basic and simple, but these and other concepts will either be the major robbers the truck’s or car’s miles per gallon, or you’ll make them your advocate! How smooth your engine is running will not only make you feel better when you drive, but will keep years of stress and strain off your motor.

Spark Plug Gap

The spark plug gap: When you read on, you can do more with the knowing the correct spark plug gap than you’d think!

Who doesn’t enjoy the performance of an automobile hugging the road; not just hearing, but also feeling the sound, the purr, of a well-tuned engine? With all the experts out there contending that the computer takes care of all that, I have encouragement for the guy (Don‘t worry I know gals are into this too!) who likes to buy their own parts, apply them and get that feeling of accomplishment that my putter has become a purr, that my thready roar has become solid and reliable. Now before I loose you and make you think that you’ll have to be knowledgeable and have many tools to make the spark plug gap be at your advantage, I’ll give you the steps you need too, don’t you worry.

Most people’s spark plug gap settings on their engine are pretty close to right, when the car is newer or when they’re first installed. My spark plug gap details will cover the scenarios where that isn’t the case. The problem is that the spark plug gap doesn’t stay right all by itself. Years ago, I was working on a dilapidated vehicle - you know most of us have had one of those - and I had enough new spark plugs for only one of my two very similar vehicles. After finishing the spark plug gaps for the newer car, it occurred to me that the older car wasn’t sounding tuned either. I checked my watch and it was too late to go to the auto store to buy more. Then it occurred to me, what if the spark plug gaps were off by a bit, or a lot. Some were 20 microns off, plus or minus, off of what they should be! Maybe I could just change the spark plug gap on the old plugs and put them back in! Those spark plug gaps, which weren’t staying gapped because of two reasons, they were a little old, and they were not made out of platinum. Most newer cars use platinum (Many ‘90 models and newer will like them). It’s tough to say which car’s engines won‘t run well off platinum, but it’s worth a try with fuel prices these days. Even back to the seventies there can be improvements made.
(9/14/15 For at least 5 years now, I've felt a lot better about iridium over platinum. Platinum now keeps it's gap about as well as copper did - very poorly. Iridium's are kind of the superior new platinum.)

Maybe ½ hour of running the engine later and some rechecking of the spark plug gaps, I realized that I needed two new spark plugs for at least two of the cylinders. They weren’t staying gapped.

I’ve since learned that platinum's gaps actually last longer and are slower to get off by as much. With out an official study it seems to me that about a quarter to one eighth of platinum’s will significantly lose their gapping within a few days of driving, depending on the manufacturer, while it looks likes 1 out of 2 or 2 out of 3 standard plugs will loose their spark plug gap in days. When the platinums are changed back at this point - when they're done being treated by being heated and cooled in the engine - they'll keep their shape much more reliably than the old standard. When checking your spark plug gaps, if the prong has kept its position accurately, there isn’t reason to change it unless there of signs of discoloration, the appearance of being burnt, or the metal is pitted.

Believe it or not, the best way to know if you’re firing evenly on all cylinders is to listen to each cylinder with a heavy metal tool. Remember to listen to your engine right after installation and once again a few days of driving later to be sure the tuning stuck! If one area sounds slower or faster, or higher or lower pitched, you’ll know that your spark plug gap is off, or your spark plug wires may need help.

Check out a video where knowing spark plug gap comes in handy.

If sparks and wires aren't enough to get that engine running smooth then you need to check out this next article telling what I learned from the Great American Jalopy, which applies to almost every car. The Great American Jalopy.

Need tuning because your car is old? Your car may be a jalopy. The jalopy is technically a dilapidated vehicle, but this article shows that it’s really the old great achievements and engineering marvels, isn’t it? Some of you really know what I’m talking about. Click above.
