Ngk b6hs

So I replaced the stock plug with a NGK and I think the stock plug acually performs better than the Ngk. Never heard of it but not a bad plug. Anyone ever hear of GreatMaster plugs? The stock one seems to have a longer piece in the Middle. Make a difference?

lol.

That is what's called a extended tip, BP6HS would be the same style.

That is what's called a extended tip, BP6S would be the same style.

I have the bullet train motor. Do you think that is the type of plug it should have. Not a lot of info anywhere on it?

If it doesn’t have threads through the head and doesn’t hit it ok

If it don't have threads your gonna be screwed putting it in!

 

[Greg58]

You don’t understand, if the threads are too long and go through the head into the combustion chamber carbon can build up and cause problems when it is taken out. Sometimes pulling out the threads in the head. It happened a lot in VW’s with aluminum heads when people installed the wrong plug.

I got a NGK TR66 plug the threads come to end but the plug creramic and electrodes steps way out into the fire bowl but it runs great so far, I'm really happy since I change the fuel mixture to run lean.
