AutoBravado's Spark Plug Wire's Perspective

Spark Plug Wires:

Do you want the gateway to efficiency, or poor gas mileage?
Do you want to know the electrical path to cooler running engines? Who wants a hot engine, which leads to engine damage?

Many go for the cheapest wires, if that’s what they can afford. If you don't cheap skate your electrical paths, the engine won't cheap skate you.. Others will spend the money on whatever is more expensive hoping that it’ll work better. Cost can have a reflection on quality, but wouldn’t you want to know for yourself what makes a spark plug wire good?

Spark plug wires and their several points of quality or considerations:

How good is the warranty? Is it limited or lifetime? If they’re sturdy enough limited is good enough, but sometimes there are very nice spark plug wires, which are less sturdy that could use the lifetime warranty.
How many ohms of resistance? This is the best way to know if a spark plug wire is good, but sometimes you just have to buy the more expensive components and it’ll get you less electrical resistance. As a rule you'll get less ohms of resistance in your spark plug wires if they're installed as much as possible in parallel to the other wires coming to the distributor cap. (Have them join together as they make their way through the engine compartment to the distributor cap.)
Is it of sturdy construction? When you pull the boot off, will the wire be torn asunder? This is more likely to be the danger if the spark plug wire is unnaturally thin. Now you wish you had a lifetime warranty didn’t you?
Know by the performance if you've made an improvement:

This might sound incredibly goofy, but there are uncountable times the people have bought the better spark plug only to have a down grade in performance and not notice. A critical component to knowing if it’s right to your car is have a feel for the car before the work is done and test whether you notice the difference. We’ve all known the people who just don’t have the sensitivity to know whether their new spark plug wires have even made a difference. That’s why countless stores across the nation will sell lower end spark plug wires and totally get away with killing the nation’s gas mileage, and murdering your car’s performance.

If you are one of those people who don’t have the sensitivity to know whether the car is any better or not after your work is complete. You may either rely on more observant friends, or you may do a couple simple tests. Before the work is completed test how fast your car accelerates over a short period. For safety, it may be wise to invite a friend to work the stop watch. Some might say, test the 0-60, but that’s a sure fire way to catch a cops attention.

The Test:
It is a whole lot easier to just drive a little slow on the freeway, say 55 miles per hour, and at a designated point and accelerate in a manual transmissions 4th gear (2nd to highest), or turn off an automatic transaxle‘s overdrive. If your car doesn‘t have an overdrive, just punch it.

Conditions for your test:
Have the outside temperature equal for both test (affects the gasoline/air mixture).
Have the engine temp. approximately the same
Use the same section of road both times.

Test those new spark plug wires! Please, remember to install them one at a time to keep you from mixing up the order.
You’re ready to find out your 55 to 65 time!

I've heard some mechanics say that they don't even bother with the spark plug gap, Read this article and learn how important this is really is. Or, read up on Auto Bravado's review on Bosch's Spark Plug Wire line in the Dodge Hemi Spark Plug Wire page.
