Spark Plugs

[riding4fun]

Aside from the standard NGK spark plug. Is anybody using a diffrent or better one.
I am currently using a NGK #5539 BR8HSA

Liquid Cooler B8HS
Air Cooled B7HS

Running BR9HIX ngk plug tonight with fuel additive on the dyno to see what improvements could be made and was quite surprised.

Will run the BR8HIX w/o any additives in the fuel, both are Iridiums and work great.
