Cost is the same, specs are identical. What's the advantage?

 

[stefan]

I Think not having the elektro, Will give a more directe spark. And it is hard top witch is always nice.

I think they will make it harder to tune, not being able to see the insulator base. The graphs on the images don't show any gain in any category.

No longer have to worry about indexing?

 

[augustaf]

Nah, we only index plugs on Chevy engines.

Maybe it would be less likely to have a runaway with that smooth plug as opposed to sharp edges. Some of those came in my outboard boat from the previous owner. It's a good running motor but I haven't tried the regular ones since it doesn't need plugs.

Fitment lists the flat tops as Marine Outboard and the BR8HS as Motorcycle. Do they come in the Extended reach variety or just the H style?

The compression difference between using a short reach compression adapter in a long reach plug head is 10 psi on our compression gauge when tested......,..
