I’m thinking about switching to BKR7E's for the summer months usual Temp in UT is 90 to 105 degrees I am running 20psi boost. I have started to notice a slight ping with the warmer weather? I am running BKR6E’s now at .028 gap they only have about 1500 miles on them, I am using 91 octane premium fuel I have pulled my plugs no sings of running lean. Any way what do you think?

 

ya 7e's wont hurt anything, would probably help eliminate any pinging too. If you run 20 psi and drive at least semi aggresively, they will get hot enough to self clean, etc.
