Cooler plugs
With other things on the car now fixed I want to start doing a general tune up before continuing mods. Part of that will of course be spark plugs. Would I be gaining anything by running a step cooler plugs? The motor is stock, intake, headers/exhaust after this but no other tuning or major performance upgrades in the near future. of course the manufacture has their reasons for what is there and I know in the future when it's boosted cooler plugs will be needed but with a setup that is still factory what would be the + or - effects?
