Spark plug and gap for 13b street port

What plugs is everybody typically running for a single turbo converted 13b street port engine.. I just bought the car and it came with ngk bkr8eix that were basically destroyed (owner obviously neglected) Car will be 10-15psi city driven.. On a gt3076r and has an hks ignition and upgraded wires

Look at Mazdatrix. RX7 plugs do not have gaps.

That's why I'm asking because the plugs I pulled out were electrode type iridiums...and I was figuring on needing the other style like your saying

Get yourself a bunch (order 8-12 at a time) of NGK BUR9EQP plugs and you'll be good. You can use the 9 plugs in all slots and they will work to 500whp+ (if your tune doesn't suck) no problem.
