"I noticed instant power increase for my Ford Ranger with a 3.0 liter V6." posted by: on December 22, 2013

"After several hours to install and using these plugs I am sorry I tried them the vehicle lugs under load and the gas mileage dropped 5 miles per gallon and you know this 4.2 liter ford does not get good mileage in the first place.. DO NOT WASTE YOUR TIME AND MONEY.. THEY WILL CHANGED SOON. i DID GIVE THEM A CHANCE SEVERAL THOUSAND MILES OF DIFFERING DRIVING.. USELESS" posted by: grumpy on June 17, 2012 view all 2 reviews

Rating: (see review/s)

"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
