Thanks,
Chuck

I'm also looking for colder plugs. If i find somthing. I'll post it up for ya

 

Ive heard that the NGK BR7EFS is a colder plug than the TR6.

This week-end was the first chance I had to call and they were closed. Will call on Monday and talk to someone personally since their web page doesn't seem to answer these questions. Will post the results here.

NGK plug heat ranges for LT-1 From hottest to coldest

TR5
TR55
TR6
BS7EFS
R5724-8
R5724-9
R5724-10

 

Talked to NGK tech this morning and they advised me that the next colder plug than the tr6 is
BR7-E7. This is a non-projected plug.

If your distributor has trouble finding it because it is a special order plug, the stocking number is 3346.

Hope this helps.

Would they foul out on a Supercharged car with 8-10psi? My TR6 plugs looked terrible after just 2000 miles. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

I've been using the r5724-10 ngk plugs with my tnt kit and I have a lot of miles on the plugs without n20. Believe it or not the car seems to run better power wise with the cold plug verses the stock heat range. The plugs dont foul out either or atleast I have'nt had any problems yet.
