I HAVE. i have tr55ix in it right now. i talked to the NGK teck people and they said they are not for corvettes. its a mistake and they are fixing it on thier web-site. for 05 and 06, they recommend TR5 and not TR55. go to ngksparkplugs.com.

also, TR55 is gaped at .059 and for corvette the idle gap is .004-.045, depending on who you ask.

I'm running TR6's in my ProCharges C6. Gapped at .040. Zero issues. The stock plugs were misfiring under boost at anything over 5500 rpm.

just to throw some fuel on the fire.....

proper plug selection is always relative. if the engine is 'stock' then stick with the 'recommended plug'. once you mod. the proper plug will be determined by the mod. sometimes you will want to change the heat range (one step cooler or hotter), the type of tip (v, etended, wire, etc. etc.), the composition (iradium vs. copper, etc. etc.). it's all relative.

personally i prefer one step cooler and a slightly wider than stock gap.

I run TR6 plugs in all blown applications and my HC packages. I have had no issues with them. On occasion I run the iridium version of the TR6 if the customer desires.

I've always used TR 6's in modded LS motors.

I have NGK TR6IX plugs in my LS2 twin turbo car, and I have had them in there for about a year now. They've been great. I haven't pulled them and looked at them since I've had no trouble with them.

based upon what you've listed as existing and planned mods. i would be tempted to start around .42 and adjust (+/-) as needed.

don't forget to index them, and make sure the wires get a good hold. for some reason, it seems, the stock ones have a tendancy to work themselves loose on one or more plugs.

It goes like this; example; take an 11:1 comp motor, a gap of say .045 from the electrode to the ground strap. This is the distance that the coil energy can arc a spark across without interuption. ( misfire) Thus igniting the fuel. As comp increases or you add boost you are creating an environment of a more densely compacted air and fuel molecules. This densely compacted environment creates a physical barrier of matter that the spark must navigate from electrode to ground strap. Yet you are still working off of a preset energy level from the coil. Since you can't increase the energy, you compensate by closing the distance that the spark must travel through this dense field of molecules. This way the energy is sufficient to create a spark positive to negative, and we have ignition. Gap is a relative unit of measure. The coils we have work very well since the plug wires are so short comparied to the days of distributors. It's measured in Ohms of resistance in linear units; the length of the spark plug wire. In lower comp motors N/A larger gaps are routinely .050-.060, and it goes down from there depending on all the factors of your particular motor. There you have it.
