Appears the Denso Plugs are out of stock nation wide, maybe I'm not looking in the right spot.<G>
And don't forget to use the right plugs, I prefer Denso IKH24
These are solid tip.Can you elaborate?
I have a PMAG with O360, using NGK plugs now just because that's what's in the manual. Seem okay but they have the stupid screw-in ferrules which want to get loose.
Let’s not get engines mixed up.
For parallel valve engines, the above NGK BR8ES (item #3961) and standard plug adapter are correct.
For the OP’s angle head IO-390 the Denso IKH27 and long reach adapters are correct. The Denso IKH24 plug can be used if you want a slightly cooler plug.

Right on, thanks Micky and Carl for the plug info. And sorry Dan for the thread-drift!Let’s not get engines mixed up.[...]
