I know this has been discussed many many times. I did a search and all it did was confuse me more. I decided to go with a 4# lower instead of a 6. Which plugs should I use? Gap also? Some say they are still running stock and some say go colder.

 

Anyone???
Will TR6's work or something more? I want to order the damn things but I want to make sure I am getting what I need.

 

Running denso it20's pregapped by Outrageous Performance at .44 ( I think)

 

I just installed a 4# and went with the TR6's gapped at factory spec. Factory spec is 0.42-0.46 (located on the sticker under the hood). I believe I set mine to 0.44 when I installed them a couple of weeks ago. Truck runs great!

If you have Advanced Auto there, go there and pick them up...like $1.39 each

 

Thanks Guys.

Fractaldragan:
Your time in your Sig. Is that w/o the 4# right?

 

Yes. I almost broke into the 12's with chip, K&N and traction bars on F1's

I probably would have done it that night had I stayed longer
