Decent price...tr6's are generally for higher compression engines as the heat range is colder. Unless your changing compression to 11:1 or higher, I would stick to 55's or an equalivent

Aren't NGK TR6 plugs for nitrous use and TR55 for N/A use? That's always what is usually posted.

^^^ Yes the TR6s are step colder, you use them with nitrous, used them in my 03 cobra when I dialed up the boost (2.8 pulley)

TR6's are widely used in boosted applications too. 55's seem to be the go-to plug for NA and normal compression.

Not to steal this thread, but I have these plugs and they are gapped at .042. Do any of you know if that's acceptable for spraying a 100-150 shot at?

TR55 are made for .055" gap. If you want to gap at .040" then get TR5. Don't gap the TR55 down to .040".
