Spark Plugs
#4
I have an early 06' with over 107,000 miles and I've noticed mileage going down a little , about 24 MPG.I've used AC Delco Rapidfires in the past and have had great performance from them as far as a little increase in HP and mileage but have heard good things about the E3 plugs which are the main ones I'm curious about.Have any of you used them or know if they really live up to their claims? Otherwise I will go back to the Rapidfires if they make them for the Ecotec.

I tried the e3's had a SLIGHT increase in milage but, it caused SERIOUS misfires I left them in for quite sometime, about 6-8 months, and gave the computer plenty of time to get to know the plugs. The engine just didnt like them though, put the stock ones back in and all is right with the world again.
