"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
Doug
"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."
Pros: More power and milage
Cons: none
