I believe some of these guys have solved some pinging issues with a simple plug change, so thats one reason.

I don't have a problem going with Autolite, NGK, etc.

My Screamin' Eagle performance plugs make my bike misfire intermittently.

Thanks!

I called cycle J&P Cycles yesterday and asked, because the 2007 FLHP runs so hot, if I could change from a DCPR7E TO A DCPR8E and got a variety of anserwers, as though no one on the planet had ever thought of this before! He also said it would effect the ECU. Any suggestions?

Thanks.

I love the spark plug claims that HP increases if you use their plug, especially 3 HP. But hey, it's your money and your snake oil .......

Ive tried most all the plugs.. HD, NGK, Autolite, Champ & E3 plugs in standard, Plat & Iridium and can say I cant tell a performance difference in any of them. Im sure a dyno may see a small difference between them. I was given a set of the HD 10R12 Dbl Plats earlier this year, gapped them to .038 & thats whats in it now. It runs just fine........

I use the autolite, tighten the nipple with a pair of pliers. It won't come loose.
