guys with the BR7's, have you had problems with them fouling with street driving? i'd rather run a safer, colder, plug but not if its going to foul every 1-2k miles. i have 4lb pulley.

 

TR5's and 4lbr no problem w/ JDM chip burn.

 

If you go one step below the BR-7EF's, you will encounter fouling every 1500-2000K miles. However, BR7's have been good to me so far, no fouling and the truck pulls harder. You do feel the miss at idle, but i prefer the colder plug and the tougness that NGK's provide over the denso's ( electrode strength ). Denso's are just way over priced but are indeed nice plugs if you can afford em. Ill take the miss and save $70.

 

Nope, not so far ... Got about 4 K on them I think....

But then I run pretty hard all the time ... <grin>

 

TR6's with a slight miss at idle but pulls hard with no miss under load. Thinking about going Denso's!

 

SVT_KY what size pulley are you running? I just bought a 4lb'er, and am looking for the best, safest plug.....most use the TR6's but you and a couple others have had problems with them so i'm thinking about the BR7's

 

4# er ... Burned the cathode right off the TR6's, as have
a lot of people. Prolly because the truck went lean for
some reason, I dunno, cause we never found out.

I agree with the other BR7 converts. The truck seems to
pull much stronger.

Also, I got "hooked up" with a fella in the SCCA club here
and get them for 10.79 for the 8 pack.....
