A lot of us have been running the very popular and primitive UREM40E and UREM38E spark plugs in our 4-cylinder Continentals and Lycomings.
I suggest you see if your engine is OKd to run the Tempest UREM37BY.
You can easily find them at Mcfarlaneaviation.com,Chiefaircraft.com, Skygeek.com,
etc.
The spark plug has the 1/2“ thread reach, and is 5/8”-24 for the harness.
It’s a wonderful plug in that has a projected tip which runs cleaner.
They foul less. And they are gonna be easier to clean and gap when the time comes.
Did a test by putting them in an O-320 and a C-90 in the 4 lower spark plug positions, and was impressed with the results.
The heat range seems perfect.
And the engine starts better and runs better.
A no-brainer IMHO.
