Ok... i have been readin alot of threads on here about plugs but everyone either talks about there highly modded car plugs or some cheap plugs.. i dont have a highly modded car.. mostly stock but i dont wanna put cheap plugs in my car either... I wanna put plugs in that will give me the best firing and will last a while.. money is no object!!!

 

A/C Delco OEM replacements will work great if are stock.

 

I just finished installing NGK TR55's with the ls2 wires in my 2001 Z06 and it runs great! Its a noticable differance, even idles smoother.. I stuck with the gap they came with .057, they are about $2 each.

 

TR55's. Why is this in internal engine?

 

Send a PM to 99BlancoSS. He is a sponsor & has a "new" low resistance plug. There is a thread containing some information about the plug in the "Advanced Disscussion." It cam up in my thread named, "Want a more advanced discussing about spark in the combustion chamber."

I changed my modified NGK's (dimpled electrode & drilled ground strap) to the WeaponX plug that 99BlancoSS sells. Through the years, have gone from a drilled & dimpled copper, to a drilled & dimpled NGK (many others in-between while testing), & now to WeaponX. Have read a lot of theory & experimented w/ a lot of plugs & modification of plugs. Only reason I stick w/ a plug & its' set-up is becasue it performs better than what has been used before (gas mileage, idle quality, part throttle power, over-all efficiency of the tune including WOT). The "spark is spark" crowd can do as they wish. My choice is WeaponX.
