Good stuff. I think I'll stay with my 6's for now since im only running 12psi from my twins. I'll try these next.

My car runs better with the br7's than the autolite 103's I ran for years.

This is my BR7ef's after around 3,000 miles. 2.6h at 19-20bs.
These are the ones I just pulled out. This is why Josh was asking about what spark plug to use.
