Br9 spark plugs
Looking to turn up the gas a bit and I'm at the end of the heat range for a 8 plug. Would need 9s.
has anyone street driven on a 9 and how was it. I don't expect it to last long before fouling but a thousand miles would be nice.
the 8s get about 1000 miles before fouled currently. Currently on .88 nitrous jet. Would like a .93
