I migh use autolite 5224 with aluminum headed 10.5:1 360. Dunno if that’s a good choice or not.
They are nothing new other brand name introduced something very similar in mid 60sI tried them in an 08 Jeep Wrangler with the 3.8 V6. It drove the computer nuts throwing code after code. I've seen people put them in other things with no benefit at all.
I was hopin maybe you were bein sarcastic. lol
Call ngk techline they are great
Well, there’s an idea! I will do that; Embarrassed that I didn’t think of it...
Is Champion 12 about the same as Autolite AR52?I wouldn't bother calling any spark plug manufacturer; they will be guesstimating at best and misleading at worst. One hones in on the optimum plug by reading plugs. There are too many variables for the phone/online sales rep/tech's recommendation charts to address. As others have said, starting at a baseline (I'd go with yellow rose's Champion 12 recommendation) will put you in the ballpark. Fine tune from there. You may not hit on the optimum plug the first time around, so plan on needing to purchase another set.
what codes did it throw?I tried them in an 08 Jeep Wrangler with the 3.8 V6. It drove the computer nuts throwing code after code. I've seen people put them in other things with no benefit at all.

what codes did it throw?
oh, just wondered, ive had 16 in my hemi and a set in my 340 for years and never a hiccup. Or code. I should try a different set and feel the difference.Random misfire and specific misfire, transmission, torque converter lockup......that's all I can remember but it was more than that. Put the stock plugs back in and it was fine again. I've heard others have the same type issues with computer cars and E3 plugs.
Is that a RC12YC plugs ??Is Champion 12 about the same as Autolite AR52?
I use Champion 12. I know a lot of people Like Autolite. I've had two plugs not work out of the box years ago. My buddy uses the expensive race type . He went racing 1st time into the season years back and was worried (had a skip) Spark plugs are new he said. Told him buy another and throw it in. Another brand new plug gone bad.
