Just wanted to share my experiences with using these plugs. I had a horrible experience basically. Popping, surging, backfiring, when into the boost. Also showed big knock (10*) and the O2 readings via DS were all screwed up... showing WAY lean and all over the place.

I bought them b/c the gnttype site says to use the Autolite23's for mid 12sec cars and under. I gapped them at .032.

I put my old R43TS's (.032 gap) back in and went for a blast and everything was back to normal. Normal O2's, no knock and no surging.

What causes this? Should I try the R42TS eventhough it crosses references to the Autolite23's?? I believe I have tried R42TS's a while back and had similar results (surging at WOT)..

What gives?

I tried them once and they ran like s#@t. I have been using AC CR42TS(truck plug) for many years with no problems. They handle boost up to infinity

This is interesting. When I was running my nitroused ‘stang I tried 6 sets of Autolites at different heat ranges throughout the years and never, ever could get those plugs to work. Popping , missing, etc. So I switched to Champions and never had a problem. All I’ve ever heard to use for these Turbo cars are the Autolites 22/23’s so I’m using the 22’s. I prefer Champion plugs myself, but if someone recommends an AC for my application I’ll give them a try! So an AC plug CR42TS may be worth trying!!
I feel like we’re making a little progress.

This brings a
to my face!!

Only use 23 Autolite with a combination above 23 lbs boost. They are a very cold plug and will foul easily if driven around on for racing only. Stick with a 24 for your combination.

Everyone in the Sy/Ty community swears by the AC CR42TS, from stock to 10 second trucks. I know we're not the same, but I do know my plugs aren't too cold for my stock truck.

Plug Correction: I am posting this twice in 2 different threads as a correction to something I mis-stated.

I tried to verify which plugs I had been running with no luck. According to my notes and some scribbles on some paper, I noted that I had AC 22’s in during racing. I called the parts store and they have no record of these although they do have the 23’s. I went and pulled a plug out but I had the street plugs in. So my notes may be incorrect with this matter since now I have no idea what was in the car..
Plugs were always a “trade secret” running N2O and I can’t believe I screwed this up but I must have..

Sorry for the confusion…

Kevin

Following the lead of Lawrence Conley, I have been using 23s and 24s for years. I have never had a problem with them. Almost sounds like you crossed two wires except you would have noticed that at idle....

Ditto what Steve said. I used Autolite 23's for years in my "everyday" driven 10 sec.GN & never had a problem at all. Used the AC's a few times also with no problems but used the Autolites 95% of the time. Take care, Jay.
