Re: NGK TR-6's or NGK-Iridiums???? Plugs will not make a difference in power. They are created pretty much equal in that department.
Where they are different is in longevity. A standard plug will have to be changed pretty often, a time consuming task on our cars. A platnum plug will not degrade anywhere nearly as fast... but not all platnums are created equal. Most platnum plugs have a small platnum disk brazed to either the strap or electrode. This will fall off the plug with 'spirited' driving. Now you have: A) A non-platnum plug, and B) A much larger than suitable plug gap. You want a platnum that has a full platnum electrode that won't fall off under high rpm conditions. The only one I know of like this is the good old standard Bosch Platnum. None of the +4 crap or anything... just the regular $1.80 each standard platnum plug. You will have the same performance as any other plug, and you won't have to change it nearly as often.
Gap it to .040" even though they call for .050"... That's too much. This goes for whatever plug you ultimately decide to use.
Good luck

Re: NGK TR-6's or NGK-Iridiums???? The ACs are a no-no, the regular plugs don't last and the platnums have that disk that falls off over 5000 rpm.
My opinion...

Re: NGK TR-6's or NGK-Iridiums???? You shouldn't gap a plug more than .010 away from it's pre-gap. So, don't gap a TR-55 narrower than .049. This is from NGK's website. Take it for what you will.
If you want to gap a TR-55 narrower than that then use a TR-5 instead. It comes pre-gapped at .039.

Re: NGK TR-6's or NGK-Iridiums???? I've got a set of Bosch Plat +4's waiting to be installed when i put my headers in. I chose them because A. I didn't want to be changing plugs ever 10k miles. B. People that have tried all other plugs including NGK's claim that the car ran jsut as good if not better with the +4's in there.
Now i'm not sayin i'm expecting more power with the new plugs, but a smoother idle and not having to change them every 10k will be a nice thing. Also, the +4's are a solid platinum tip, not plating or coating to flake off like mentioned above.

Re: NGK TR-6's or NGK-Iridiums???? I agre with the Bosch Platinum +4's....they are a great plug and it sure beats the pain of having to switch them out very often....When I put them on...i noticed smoother idle and a definite good throttle response....all around better performance feels.....

Assuming that the plugs were functional, gapped correctly, and the wires were reattached properly, I cannot imagine such a dramatic change from a half heat range colder plug alone.
With regard to platinum plugs - my understanding is that the issue with ACDelco platinum plugs failing has long since been corrected. The ACDelco Rapidfires are a good plug in other applications - don't see why they wouldn't work nicely on an LS1. Also, NGK makes a platinum version of the standard V-groove plugs designated with a VX suffix (i.e. TR55VX would be a platinum version of the TR55).

Re: NGK TR-6's or NGK-Iridiums???? My car came with TR-5's I swapped them out @ 55K miles with tr-6's gapped for Nitrous. I noticed a HUGE difference in throttle response NA it was unbelievable compared to those tr5's. WOT & just blipping the throttle is a ton more responsive.
BTW TR-6's love spray <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: NGK TR-6's or NGK-Iridiums???? I've used TR-6s, TR-55s, and AC Rapidfire #12 with excellent results. I give the AC 12 the nod for the best, longest lasting LS1 plug. While it is platinum tipped, it does not have the button on the groung strap that seemed to magically disapear.

Re: NGK TR-6's or NGK-Iridiums???? I'm using 6's and gapped at 38. I may have picked up 1mph, and no change in mileage, but the 100shot, well, thats another story......
As for the iridiums, i asked a couple months ago. I got little response, but can pass this on: they last longer, burn cleaner, and can spray on them no problem, just of course a colder plug. So, it would make sense that Ir. will make more power than any other style/composition plug. I will be changing over to them once i get my use outta these TR6's, I will be using IT20/22. Good-Luck.
