some one told me today that the denso plugs were crap n not to buy them what do u think
I have tried almost every plug to see which ran better. The denso are not crap by any means. But, for are cars it worthless. The only plug that really seems to burn right on a stock is Motorcraft coppers or double plats, that it!
Anything else you will start to get misfires and whatnot in a matter of a few thousand miles. I don't think anyone had yet to figure it out but, who cares the motorcraft are 15 bucks.
I am running zex plugs but, i have the massive setup. (MSD coil, msx90 wires). So i don't what or how it would run on a stocker system. I quit the juice so i am going back to double plats.
Also with a stock coil if not boosted gap the crafts to .55-.57 and continually to open it up until you feel a misfire or at .60
With a MSD or demon you can open it up to .65-.67 range.
Folks, this will clean up your idle like a charm. The mistake most people make is buying an ignition system to clean the idle. Its mainly they tell you to get copper plugs and open the gap to .60
When simply gapping on a stock coil will get you virtually the same effect.
