I am looking for these Gm part #'s...... The LT4 badges that came on LT4 vette's? The plastic, fbody, M6, shift boot retainer? O2 sensors that screw into Long tube headers. Also now that Ngk tr55's have been discontinued, what plugs are ya'll running in your heads and cam cars? I need some help on this so my Brother and I can get his Formula ready for the 2007 Power Tour.

Thanks alot,
Steve

 

Ttt!!!!!!!!!

 

Where did you hear that the NGK TR-55s were being discontinued? They are still being sold on Thunder Racing. As for the oxygen sensors and long tube headers, your exising 02 sensors will thread right in the headers. However, you will most likely need 02 sensor harness extensions so the factory harness and reach the connection on the sensor itself. Not sure about the part numbers.. you could always check Shoeboxes site, he has many GM part numbers listed there, it may turn up something. www.shbox.com

 

TR55, stock # 3951 are NOT discontinued..... Dont know where you got this info......

 

I agree. I just bought a set last week.

I see you're in Texas...go to your local O'Reillys and tell them you want NGK 3951's.

 

i personally like the autolite 104 copper core plugs, cheap and they get the job done.

as for o2 the stock ones fit in LT's but if you have a decent amount of miles on your car you may just want to replace them unless you know they were replaced recently.
