Thanks for the info Carl,
Looks like I screwed up and have a set (4) of the SR adapters, they are 3/4” overall length.
If anyone needs a set they can have them for a $25. donation to VAF, I will pick up the postage in the USA.
Thanks for the info on the plugs Walt,
Appears the Denso Plugs are out of stock nation wide, maybe I'm not looking in the right spot.<G>

I am certain that there is an NGK equivilant to this plug. NGKs are also good plugs and often used on lycoming's with good results. I use them on my 540. Th 8 heat range on the NGKs is the most used on Lycomings with 8.5:1 CR pistons.

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.

Denso 24s are hotter than 27s.
Right on, thanks Micky and Carl for the plug info. And sorry Dan for the thread-drift!
