Hi guys I recently acquired a 36 roadster deluxe, and wanted to know what are the best plugs for a 21 stud 36 motor? I know champion have had some criticisms so what are you guys using and have found works well? Thanks

I still use Champion 555 UD16. It has worked well in my 36. terry

Speaking from experience, what cylinder heads do you have? The Offenhauser heads take a plug with a half inch thread depth, the Edlebrocks take the 3/4 inch thread plugs. Put the 3/4 inch plug where a half inch plug goes and you get to rebuild your engine after you dig all of the spark plug debris out of the cylinder walls.

Champion UD16. Have for many moons. Never an issue.

I have stock heads . Checking to see if there is something better than the champion for a 36 engine.

What do you mean by “better”?
I don’t know of anything you could improve on. Mine have performed flawlessly for many moons. If they are not working for you possibly you have other issues.

I have found that "run of the mill" Champion plugs may suffer from poor quality control and manufacturing processes these days. However, I have not run into this problem with the rather specialized plugs folks like us use, and in fact, I prefer Champions in most cases. I use "L82YC" extended tip plugs in the Edmunds heads that I prefer and have found the completely satisfactory (the set currently in my '51 have been there since I installed the engine in 2016). Interestingly, all of these plugs I have purchased were made in France.

Better as in champion have suffered poor quality control and poor manufacturing processes.. I don’t have anything wrong with my engine. But of you do a search here you will see many have had an issue with champion plugs, so I asked what are the alternatives being used .

Brian · 11-27-2023, 11:54 AM

A good alternative is NGK A6....NGK AB6

Tim Ayers · 11-27-2023, 12:04 PM

I think the Champions most folks had issues with were the recent production H10's.
