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."

Failed Plug
March 4, 2013
By Escort
Cons: Failed after 1 month
"Bought 4 of these to tune up my Escort. 1 plug failed after about a month. I have never seen a new plug fail like that. When I replaced it, the miss went away. I will be removing the others and going back to Bosch plugs. These are copper plugs and are not long lasting like the platinum or iridium types."
