"these plugs work great as of 20K miles the car runs well and notice no lack of power." posted by: JT on January 30, 2012

"Replaced the NGK's in my 740i with Bosch plugs and that was a mistake. I had 133,000 on the NGK's and they never missed a beat. I did not know what brand was in my engine so i bought Bosch. Performance is down and horsepower is less. I use to race back in the 60's and used NGK's and they were great. Nuff said." posted by: on February 22, 2010 view all 8 reviews

"Excellent Quality Sparki Plugs. Previously, someone had installed inferior Quality Spark Plugs in the Vehicle and they affected Performance. Installation needs to be carefully...Engine Cover has to be removed, Electrodes have to be extracted (affixed with Screws), Spark Plugs are set very deep inside of the Engine. There is also a Ground Connector that should be disconnected and reinstalled carefully. Spark Plugs do not need to be gapped. One must take the Time and Patience to put them in correctly or entrust someone who is both knowledgeable a Patient in order to do the Operation. The Spark Plugs are giving an excellent Performance since they have been installed." posted by: Vitznau on September 29, 2014

"I put these in my Vtwin motorcycle in November. In March the bike quit running. Took it to a dealer and all he had to do to get it running was put normal plugs in it. Hope nothing permanently damaged. Told a friend about it after the fact and he described the same trouble with his Chevy truck. His mechanic said they burn extra hot and mess up the computer sensors." posted by: GOC Sensei on March 12, 2014

"I replaced my 10 year old ----- Platinum +4 spark plugs which I was still getting 38 MPG highway with over 225k miles. After replacing with E3, my MPG fell to 32 MPG highway. Disappointed to say the least. I'm returning and going back to a new set of +4's." posted by: MJ on December 19, 2011 view all 8 reviews
