2011 Corvette GS Results
I installed a set of E3.54 spark plugs in my 2011 Corvette GS with the 6.2 LS3 . I'm using the OEM coil packs and Taylor Thundervolt 8.2 spark plug wires. The car runs smoother at idle and pulls strong all the way to red line. I didn't do a before/after dyno test so I can't speak to specific horsepower gains but the engine runs great and I haven't experienced any misfires. With the OEM plugs my exhuast tips were always black with carbon residue after a day or two of city driving. After installing the E3 plugs and Taylor wire combination the exhaust tips are staying noticably cleaner and I only wipe them down every couple of weeks and there isn't much residue so it seems that I'm getting a cleaner burn. After 10,000+ miles I'm very pleased with the spark plugs and just ordered a set for our 2013 Cadillac SRX 3.6.

WOW
Installed these in my 2007 Chevy Avalanche and couldn't believe the throttle response. As soon as I stepped on the accelerator pedal I felt the difference as the truck jumped forward with a power increase - now that's what a V8 is supposed to feel like. Since then I've installed E3 spark plugs in all my vehicles with similar results. Whenever friends ask what spark plugs I recommend it's always E3 !!!
