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."

Horrible plugs
February 22, 2013
By Saaber
"Got these plugs for a 2007 Saab 9-3, after 2 months, the engine started to misfire, not a good fit for the car as listed. Changed to Denso plugs no more problems."

Absolute junk
July 19, 2012
By Greg
Pros: None
Cons: Do not work as advertised
"I put these in my 06 Ram 1500 4.7L and watched my mileage increase for the first 5k and then drop to 12mpg highway for the next 10k. Thought it was just a dirty engine until I got fed up enough to change the plugs out. I switched to NGK V power and back to a consistent 18mpg on the highway. That was a year ago. Don't waste your money on these. They DONT WORK."
