"An excellent location for people to easily get the purposes of cars and thank you" posted by: alking on May 4, 2014

"Had trouble with engine missing. Not certain if problem was related to bad gas bad coil (no codes) or bad spark plugs. If you are changing coils you might as well change the plugs too. Sprayed electrical silicone on threads prior to install to aid in installation on an E350 V10 Ford Engine with plugs hard to get to. Also replaced the PCV valve & fuel filter and added Sea Foam to the gas tank. Saved hundreds of dollars for a tune-up as the 2000 Van runs great now even in the cold!" posted by: optyman on January 8, 2014 view all 3 reviews

"I installed a set of these Champions after 6 of 8 OE plugs broke off in head. I have about 5K miles on my Champions and I can't find any fault with them. Runs as good if not better than my old Motorcraft plugs. Increased throttle response, easy starts, smooth idle, engine pulls hard all the way to red line. I highly recommend." posted by: Jim on August 4, 2008

"I replaced 4 original spark plugs with E3s. Car ran well for 57 miles then picked up a misfire. I checked everything but the spark plugs trying to figure out what was wrong. I had changed plug wires and coil pack at the same time. After exhausting all else I pulled the brand new plugs only to discover the #4 plug was not firing properly. Replaced it and the car is fine. All plugs will be replaced now! I have never had a brand new plug short out in my 45 years of working on my own cars." posted by: Jim on October 3, 2011

"dont recommend in a 1999 chevy cavalier 2.4 l. they make the engine misfire. had to change back to the good old double platinum and the misfires stopped." posted by: on January 22, 2011 view all 5 reviews
