What do you guys recommend for replacement spark plugs. It's about time for a tune up on my car. Need new wires and plugs. Thanks! 3.8 non super charges 05 LT

 

If you have no mods, I recommend going to NAPA or an equivalent GOOD parts store, and get the stock stuff. NAPA sells the AC Delco (factory stuff) with their Belkon spark plug wires... pop them in and you're good for another 100,000.


Trying to go after these trick spark plugs or a cooler one is useless unless you've got several mods on the car .

 

Hmmm mobs....I have a K&N intake, the U-Bend Delete and a tuned PCM from 3800 Performance. Any of this stuff matter?
