I have a stock ls1 Camaro. all I am going to running is shorty headers. cold air intake and flowmaster exhaust. maybe some time down the road larger throttle body and different gear ratio. I bought 8.5 mm msd ignition wires and autolite rapid fire plugs. should I get the ngk t55 or the rapidfire just fine??

Went TR55 gapped at 0.045 (per John at TSP) for my bolt-on LS1 and no complaints. Will only change them when I spray in about a year.

I like the ngk also. Just curious has anybody ever run the autolites? I now my turbobuick loved autolites. I would like to try them in a ls1.

NGK TR55 is what I'm running on my heads/cam WS6. No complaints here.

autolites are easier to read the plugs...
NGK you have to get it hot enough to burn off the coating before you can read the plugs.

both work well

NGK will work fine.

I have heard people having issues with the NGK's. I personally have used both and although I have never had a problem with NGK's, I prefer Autolites.

Plain old standard Autolite 103's here in my motor

Autolite's are all I run in my motor. I have seen enough NGK's in a bucket that were replaced with Autolite's to sway me from spending the extra money on them. I have never had a single issue with a Autolite plug.

For those of you running the NGK plugs: How is the corrosion on the shell doing?

What autolite plug would match a ngk tr6? My car does not like the tr55. I will try some autolites.

If your running N/A like I am I'd just run the Autolite 103's. They are cheap & have never failed me. I know alot of other people who also swear by them & will only run Autolite. they don't get the publicity like NGK, but they perform which is all that matters.
