E3 Spark Plugs
Its time to change the sprk plugs on the truck and was wondering if anyone has used the E3 Spark plugs. I've always been a believer of sticking to O.E. parts, but I really like this concept. Thanks for the help.2005 Chevy Silverado Z71 5.3 ext. cab

its a gimmick they still only have 1 spark. their supposed to last longer because when 1 of the tangs goes bad it has 2 more but by that time the electrode is usually shot
go w/ the delco'sGM TECH

Ive always usedBosch Platinum 4's and they work great but ive always heard that for vortecs, ac delco's are the only way to go. Is this true? Should i stick with my bosch's or go to delco's?1995 Silverado,Z71, 3-inch lift,2-inch leveling kit, SkyJacker Suspension, short ram-air intake, throttle body spacer, MSD ignition coil, straight pipes

I have nothing but bad experiences with Bosch spark plugs. I have techs in the shop that refuse to install them. The E-3 looked apealing, but I'm sticking to A/C Delco. Thanks for the input guys.

NGK and Bosch are great for rice burners and foreign jobs, but I have had too many people bring there vehicles back because of miss fire codes in the computers from NGK/Bosch plugs. I won't put anything other than OEM plugs in vehicles at the shop. Warranty work cost too much and too much of a hastle to exchange plugs. GM=AC Delco!

i tried bosch platinum 4 plugs in my rhd crx and i actually lost performance and fuel economy(bigtime i swear it thought it was a v8 instead of a 4cyl for how much fuel it used) also it kept popping off my leads right off the plugs and my check engine light came on a week later
