Same Denso quality

By Kenneth Ashley Williams on 4/5/2010

I knew without a doubt that I was going to use Denso Iridium plugs. I used them all the time when building B-Series VTEC motors for myself and my friends. I didn't know how the K20 would respond to them, after all I'm still an old school Honda guy, but the Denso plugs came through as always, noticed a tad more power, probably due to the higher spark efficiency and better burn. The KPRO likes them a lot better also, able to dump a little more fuel in the high end that what I was without massive clouds of black smoke! Good, bang for the buck, no pun intended!

New Plugs work great

By Angelo Said on 9/18/2008

Not much to say on these besides I installed them replacing older plugs. And the car was once again restored. It was easy to start ran good and was just like new! Great quality on them and for this price it's pure astonishment. These plugs go for so much more at auto part stores!
