posting for a friend. He has an 02 WS6 A4. Full bolt-on with H&C, stall, and N2O. I've done some research and it seems that the NGK TR6 plugs are the way to go. Question is, where can I get them and what gap to set? Thanks for any advice or help anyone can give.

 

I bought mine @ NAPA which was the only place loccally that carried them.Gapped them @ 35.

 

O'riley usually has a pretty nice selection of NGK's too, that's where I buy mine at. .035 sounds like a nice gap to me!

 

Just installed my TR6's last Sunday gapped at .038 for N2O

 

Mine are gapped at .038, got the TR6's from Advanced Auto.

 

Thanks guys for all the help and advice, I really appreciate it.
