However, I just put in Torquemasters (TMs). GS is now like a rocket ship. Unfreakinbelievable.
REEEEEEEEAAAALY? Hmmm, I was sold on the NGK's.

In your experience where is the best place to purchase TM's?

Got mine a while back thru Steve at Carson. There was a group buy at one point. I think I paid about 11 or 12 bucks a plug. I remember paying 6 for NGKs at PepBoys. So TMs are just about double. At this point I'd say they're worth it.

I would go with Steve as he knows exactly what you need, courteous and prompt with service and at a great price, though you can get a little more info on TMs at their site, http://www.extremespark.com

Have used both and the Deno's wear faster vs the NGK's. Tested in my Tundra, GS4, and SC. Performance wise they are the same to me new.

NGK is going to be very convenient for me to get, TM will not. (I'm an impulse buyer)

What I believe I will do is stop by the auto store here in about an hour and pick up some NGK's then I'll order TM's this month and after 6 months I'll swap them while the NGK are still fresh to see what difference it makes.

Yeah, O, that's similar to what I did. I had the stock Denso Iridiums in for about 20K, then swapped in the TMs. Big difference for me.
That's a good way to try it.

Somewhat offtopic, my buddy, who owned a beautiful 93 MR2, fully modded, told me something i found interesting. I bought myself some NGKs and told him they were plats. Well he said, he would prefer anything thats copper. He said the copper ones are the most conductive of all the metals available for spark plugs.

NGK are installed from the factory and I'm sure the TRD are just rebadged NGK....
