PTCruzin42, I use the Champion single platinum plugs Gapped@ .042
The champion# is 3032, and the plug code is RE10PMC5. These plugs are 1 heat range colder than the stock plugs. I currently have Magnecore 10MM Racing Plug wires and a Screamin Demon High output coil as well. This setup works great. Be sure to gap lower than the .050 recommended by the mfgr or you may get misfires at High RPM.
I currently run a TurboXs dual stage boost controller,w/boost on the 2nd stage @ 13.5 - 14 lbs boost, so stage one higher boost should be no problem on this ignition setup. I don't care much for champion plugs, but I have found no one else who makes plugs to fit the cruiser. BTW SRT-4 plugs will not work, (different cylinder head construction) not enough reach, and NGK, and denso Iridiums do not have enough Hex Shoulder to tighten into the cylinder head. Hope this helps.
