Is it just me or are these getting hard to find local? My local Oreilly and Autozone don't carry them in store anymore. Where do you guys get them?

I got mine at pep boys, Autozone didn't carry them...

I have two sets sitting around, if you want them, PM me.

i get mine at MTI usually, walk in with a 20 walk out with plugs lol

Napa always has them for me.

My O'reilly carries the TR55 plug for our specific trucks. Isn't the TR6 actually the plug for an LS1?

TR55 TR6 TR7 are heat ranges, the TR55 is stock heat range for any LS Motor or truck motor (still an LS)

the higher the number the "colder" the plug

boosted guys have to run colder plugs to reduce detonation

Thanx, Mr Sandog. I'll check NAPA and if they don't have them, I'll PM you.

word i work at advanced we dont have tr6s unless u order them just stock tr55s

I just bought a set at O'Reilly last weekend for $1.59 each - CHEAP! They were the only ones local that had a set in stock.
