Hi All.
What spark plugs do you suggest for a stock engine with 4x3 V coils and Boyer Brandsen I.E.?.
Thank you.

4x3 V coils

Do you mean 3x 4V coils?

I use NGK B8EVX (T160 Trident, Tri-Spark EI).

Hi Les,
thank you.
Sorry, 3x4V!
I can find easily B8 ES,; what is the differences between EVX?
Thank you.
