Thread: confused about which spark plugs and wires to use?

Stock wires, they be cheap, or any lifetime wire set at the auto store.

If you want to drop pullys, your need exhaust mods first, just so you know.

As for plugs, how often do you want to change them.

Ac delco plugs will last atleast 75k.

Most modded guys run AL 606 copper cores at a basic mod level, they need to be changed every 13-15k miles, but at under 2 bucks a plug, its cheap.

[QUOTE=Linebacker;788951]2005 gtp comp, it has the gen 3 supercharger[\quote] You should have a GenV, Not a GenIII.

1. Folks here would suggest saving $150 on the CAI box and just going open cone. HP difference is negligible.
2. Don't bother with the 180* stat. It won't do anything for you.
3. You need exhaust mods to touch you supercharger pulley. So don't touch it.

You change heat range when you experience knock with smaller supercharger pulleys.

There is no advantage to more expensive wires until you go over 3-400hp. Just buy store brand lifetime warranty wires.

AL606XP is equivalent to stock. It's iridium. Copper ones need to be changed every 15-30,000 miles because our engine chews them up.

You don't need to move anything to change them. Spark plugs on this engine are not only easier to do than on a 3400 because they aren't hidden behind the exhaust manifolds, but there's more room for your arm.

A 185 wont hurt, do it as maintenance.

Local parts store will have ACdelco wires with a lifetime warranty, change them as often as you like lol. 99% of modded GPs dont need anything other than stock. The only advantages you would see with a quality aftermarket wire set would be less radio interference.

Unless you start to go 3.4'' or lower stick with autolite 606s. Ive been running the same copper plugs for 60k, so i would say they do not need to be changed as often as most say they do.

Link in signature has plenty of info.

Why does no one want ze search?

It's preventative maintenance - all electronics vary in quality. Sounds like you got 6 strong plugs and a nicely-performing engine if you're still getting good mileage and power out of copper plugs at 60,000 miles. But Autolite even said that their copper plugs start knocking in as little as 16,000 miles (though many last longer) in a 3800 because of the exhaust-spark system.

Nope, don't waste your money.

If you mod in the future 180 tstat and turning the fans on sooner with a tune will help combat kr. Also build your own intake there are a lot of write ups on how to do it, and much cheaper. Even if performance increase is negligent, the change in how loud the supercharger whine is worth it imho.
