Hey guys. Been working on tuning my twin turbo cobra and hoping to get a little feedback on these plugs. NGK BR7EF’s, e85, 15psi and 17 degrees timing. #8 seems to be much cleaner than the rest. I’m still educating myself on reading E85 plugs, so I’m not quite sure what to think of these.
These had 3 quick pulls and a little street driving on them.
Any input is appreciated.
