Bosch Spark Plugs
« on: March 17, 2021, 08:48:16 PM »
My research suggests the NGK D8EA equivalent is a BOSCH X4CS. Correct? Anyone ever try them?
With the frequency of failing and fake NGK plugs out there, I’m curious.

I may try a set of them John.
The Beemers have a real strong spark and I wonder how that will affect running them in our Hondas:maybe they'll run cool with our stock coils ?

No idea, but since Terry started the discussion, I’m curious. If I can find a set, will try them.

Try Denso X24ES-U while searching about the Bosch.
You can never have too many spark plugs ;D
