Each photo has its description at the bottom. All these plugs seal, and do not protrude too far in. The Rx-7 plugs get the closest, and would be the best for power as long as you don't need anything colder than a 9 NGK heat range. The bur9egv are available much colder, 10/11 etc.

Hey! I recognize those housings! I'm glad they got to "live on" beyond their useful life.

Notice the problem/difference between pic 2 and pic 4?

Turblown

Yeah thanks for the housing

There is a big difference in spark plug reach, but the Rx-7 one still works. Its a tight fit, but there is room. This is the best pic I can get..

I am not real familiar with the board discussion on this, Dave just mentioned something about it yesterday and I got curious...

Yeah. You cut the trailing plug port seat out.
Can you cut directly down into the seat without destroying it on the other housing?

leading on bottom and trailing on top?

Hey, I recconize those plugs! The rusted crappy one is what was x-threaded at the dealer 2 years ago..

Good to see the cut-a-ways E



You are correct.
