stock ignition, 93oct 20ish psi

what about 2667 or 2669 for that matter?

thanks in advance for your input.

 

Yes I run them on my Miata (GTX3076, ~28psi) and they work great. We also run these on other high performance vehicles as well.

 

I use the

BKR7EIX

 

pretty common in turbo miata land, I think the one he referenced are one index cooler

 

The BKR7E-IX is a little hotter so great for an N/A or typical ~250whp Miata. They would misfire on my car at 17psi.

 

These are a waste of cash in my opinion. I tried them, the Denso ones too, which are nicer in my opinion. In the end I put BKR7E's again, which work just as well once I found my marginal ignition wiring crimp(the real problem.) Just change them often.
