first off, its recomended to run 2 steps colder than the stock heat range right?

so im wondering, if the stock h22 heat range is 6, does ngk make a bkr8e? just like the bkr7e just 1 step colder.

im going to be running around 12psi on the street (since my wg spring is a .7bar) and around 15-18psi at the track.

6's: 300-350whp level
7's: 350whp-450whp level
8's: 450whp-600whp level

I pretty much use the 7's in everything i tune and run, which is overkill. You'll get better gas mileage and partial throttle response with a hotter plug since it combusts the mixture greater.</TD></TR></TABLE>

12psi would put me in place for the 7 heat range, but 15-18psi would put me in the 8 heat range.

so, since my stock heat range is already 6 should i go with 7's or 8's?

 

up

 

anyone?

whats your reasoning behind this? ill be making power that would put me into the 8 heat range at the track though?

 

deciding on the same things, bkr7e or bkr8e

 

You car ends up running cleaner as in Idle.
