Heard About 'em, Installed 'em, Love 'em by Fast Bobby, February 27, 2010

I replaced by Corvette LS2 spark plugs with Bosch Platinums (had those in my BMW 5-series and they ran great) but noticed that the engine seemed to lack what it once had with the original AC Delcos installed. Heard about the E3's on MuscleCar TV (they tested them in the LS2 for comparison with... you guessed it... the Bosch Platinums) and they got an 8 HP gain. So I tried 'em and zippity doo da, very noticeable power gains. Engine raps up quick with lots of low-end torque, just like it was new. Highly recommended.

I purchased the E-3 plugs hoping for better fuel mileage I got a slight increase in lowend torque but not much in way of fuel savings. I would recomend the plugs but I cant guarntee the fuel savings or the power increase.
