"Great spark plugs! A little on the high end however, I have never noticed a difference until I installed these plugs. Engine seems to be running at a higher efficiency. I highly recommend their installation, especially on high mileage vehicles." posted by: Aquaman on October 13, 2011

"Bosch makes good quality spark plug, Mine had a pretty good spark plugs for stock but after changed even spark plugs don't incrase HP,I still able to tell the different. It goes more smoothly when shifting in my case(manaul) I like it" posted by: KK on September 26, 2010 view all 2 reviews

"The are the exact plugs that the dealer uses...I have a 2003 corolla...and said no other should be used. We were putting other types of plugs in...what a difference these make in performance and power...gas mileage remains to be seen...just had them changed. (another note...only use dealer ignition coils...or find out what they use...I had to return those)" posted by: Rosey on May 14, 2011

"I bought these for a 2006 V6 3.3 Sonata. They installed flawlessly the car appears to idle smoother and have an increase in power. These were the best plugs I could get from Denso, I won't be changing them for 100k miles. Would recommend." posted by: Dirk on March 14, 2010 view all 4 reviews

"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
