Hey guys,
just curious as to what spark plugs you prefer and what results you've found. I'm running u13 motor tuned and running 10psi on e85. Gap sizes ? Make ? Models ? I've had iridiums before I liked and others have told me standard plugs have been the best for e85 and all sorts.
What do you think ?

0.8mm gap is a good start for turbo and should be fine for your boost levels.
I generally stick with NGK brand. Heat range would be fine at 6 or 7 depending on how hard/hot you push it.
I stick to copper plugs but mine doesnt get driven much, probably get a bit more milage from iridium plugs but its a bit of a price hike.
So BKR7 gapped to 0.8mm would be a good starting point.
Awesome! Thanks for the info mate, just gives me a better idea on which way to go
