Not impressed
September 1, 2014
By Rob Zman
from Swedesboro, NJ
" I guess it depends on which vehicle you use these in, but my experience has been disappointing to say the least. I own a 2009 BMW X5 3.0 xdrive with 60k miles and installed these plugs August 2, 2014. the car calls for a Bosch or NGK double platinum. Against my better judgement I went with the E3s. My mileage went down to 17.7 mpg from 20 and there was hesitation when accelerating. I have pictures showing my 60,000 mile Bosch compared to the 2,500 mile E3. The E3 had an extreme amount of carbon deposits while the OEM Bosch plugs had normal wear. "

Quality plugs
November 3, 2013
By Maintainer
from Rockford, IL, USA
" I have purchased my second set for my 1998 Dodge Ram 1500.
My first set have lasted over 6 years!
I had 1 plug foul when I first bought them but I called JC Whitney and they replaced it in one day by mail.
These plugs increased my fuel mileage approx. 2-3 mpg and have not failed me.
I recommend them!

I'm a fan
May 29, 2013
By Doug
Pros: More power and milage
Cons: none
" I am a fan of e3, while there some haters out there I haven't had any problems. Note, when replacing plugs I replace the wires and coils with high end aftermarket ones, so, maybe that is why I have no problems. "
