I'm building a turbo 97' miata and I'm left kinda clueless about exactly what kind of spark plugs i should use with an 8 PSI setup.
my best guess so far is the NGK bkr5eix, are they ok?
any suggestions?
Stock 1.6 plugs or BKR7Es. I run BKR7Es gapped to .025 at 15psi on my 1.8 with decent results. Anything over 12psi really wants a different ignition system.
