Just ordered a set of these and just wondering if Ltnbolt and some of the others still like these. Wanting something colder than my TR5's but I knew the TR6's hurt your MPH a little, and miss a little. thanks...

 

Don't about the 93's but I ordered the 103's based on this info from www.sparkplugs.com

both the tr6 and the it22 convert over to the autolite ar103

thank you,

I have a set in my garage just waiting to be installed I may put them in on thursday. I currently have the BR7's in right now. I will post what kind of difference good/bad they made

 

TR6's do not hurt your MPH, and in my truck do not miss at all.

 

Oh some of the guys were saying that they lost a mph w/ the TR6's and gained it back when they went back to the TR5's. And the throttle response is supposed to be a little flat and the idle is a little rough also. Now I have not installed all these plugs and tested them, I know I'm not going to change them that often but some of the guys have. I just have to go by what I read I guess.
