NEED to know what spark plugs to get

[ptcruzin42]

Hey all, I need the help of the gear heads here for a minute. I am having my stage one kit installed next monday and while they are doing the work I am also having some mopar performance ignition cables installed and I wanted to get my sprak plugs change dout too, problem is, I have no clue what kind or size or anything of spark plugs to get. Can someone please tell me the best company, style, size, or any other information I may need to know, to get the best plug for my turbo engine.
Thanks

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.

Hey Gear head, I find that that head on the SRT-4 and the GT have the same part number. Also the hot rod aricle on the GT Turbo engine says this "The cylinder head is the same for turbo and NA engines, though the boosted application uses Silchrome-1 intake valves and Inconel exhaust valves". My understanding is that the only difference is the intake set up and the PCM. I don't see how the SRT-4 spark plugs won't fit. No flames intended, just asking....

The PT cylinder heads have a counterbore that effects NOTHING except the type of spark plug being used. I have pics to post, as soon as cardomains web site is a little less busy, I'll post them.

Here is the SCOOP on the SRT-4 Plugs vs the PT GT Plugs.

Great work Alan!

The only plugs I have found that will fit other than the stock Champions are Champion RE14PLP5 Double Platinum plugs.

I got the RE10's in mine and they work great. They art gapped at .39.

I wish that I could take credit for the work, but this came from the PTCC forum. Bob Stockum did all of the work, all I did was figure out how to get it posted here. But it illustrates why its hard to find other plugs that fit. These plugs are the same plugs that go into the V6 minivans (so I have been told). DC must have had to do the counterbore strictly in order to use these plugs. Like I said, i don't care for champions but these seem to be working great AND THATS ALL THAT COUNTS !!

They are also in the 2.7L Stratus. It takes the 10's.

So if the counter bore is the ONLY difference - is DC protecting a cross market deal with Champion. I've contacted NGK and they are "in development".
