Hello guys I'm wanting to do the plugs on my car and just wanted to get some opinions on what plugs I should buy. Its got 70K miles on it with no major mods just CAI, longtubes, X, catback, and a can tune. Just didn't know if I should stick with stockers or go another route.. Thanks in advance.. :beer::rockon:
Question about plugs
- Thread starter Roush150

Ngk tr6.
TR6 IX's
We have about the same upgrades..
Ive been using stock oem..the 1st run..
See cobra bobs faq for full part number
At 100k they still look new..
+1 I've run OE, TR6's, TR6IX's, and TR7IX's. By far the 6IX's run best including much better throttle response than TR6's. The 7IX where just too damn cold.
TR-6's here ... gap at 0.032" to 0.035" 
I run the TR6s and like them but my car is rarely driven and I change the plugs out annually. If you put a lot of miles on your get get some NGK Iridiums and once you swap them they will be good for years.

Seems like a big gap for your boost and power level. I was at .032 and could hear what I believe to be some break up at WOT in the upper RPMs. Exhaust note sounded off a little. Dropped to 0.0.28 and it cleared right up.
same thing I was thinking
