Brent, these plugs, decent for the street, how many, miles/bottles before you swap 'em? I am going TR6 @ .038 on a 175shot (was for teh wet kit), but now I have the NXL, 180jetting, and looking for the missing power from the kit. Thnking plugs, and then retune the AFR a little leaner on NA side, and pull timing..but the plugs are so easily overlooked, thinking TR8s with maybe a .030 gap for the 180shot?

I work at an advance in florida. If NGK makes them any advance can get them. And advance price matches so if you were to happen to say you could get them cheaper else where i techniccaly have to price change them. Within reason of course

4th Gen, Andrews already there, but the TR6 arent cold enough appearantly. His timing is only 26*, with an afr of 12.5:1 NA, and about 10:1 Spray, not really accurate on the afr part cuz we didnt wideband it with my LM-1, but he puffs when the A4 shifts and plugs are rich...using mix 92 & 103 also.

TEA Brent or others in medium shot sizes....
I got the R5724-8 plugs, and read that you use them at .025" for a 250 shot, and use for street. Now using on a 180DP shot maybe open up to .028-.030"? And on a wet 150-175 shot, maybe a tad more .030-.032" or am I just wrong?
Thanks,
Charlie.

Ok got the -8 plugs and decided I will try a gap of .030 it is colder than tr6, so I shouldnt need to clamp the gap down as much as the 250shot Brent is running. Figure 150-180 .030 should be safe.
