sr20det 300whp what plugs and gap do you run?

Just like the title says what spark plug /heat range and gap should be used when making 300whp?I searched and just found one person recommending BKR8 and no mention of gap.

8 is too cold.

NGK BKR6E or BKR7E copper
.028-.030”

Results may vary depending on your air/fuel delivery, but that will get you in the ball park. I run a built 400hp setup and use BKR7E coppers.

Thank you!My air/fuel will probably be a tad rich as its a enthalpy ecu tune,I read they tend to tune safe so slightly rich and ret timing some.So In your opinion would you choose NGK BKR6E or BKR7E copper for 2871 turbo tuned by enthalpy?

i would do the BKR7E

you could ask Martin what plugs he recommends for his tune. I have always used BKR6E copper. Increase gap until spark blowout and then close a bit.
