NGK BR7's on a non modded motor

[ChuteboxeL03]

Iam gettin a buddy of mine that works in parts department to hook me up installing the sparks, but the thing is i need to bring it to the shop. My question is can i drive it from the shop to my house with a colder plug in, untill i throw my 6lber on?

Thanks, Gino.

Yup. The BR7 is too cold for you though. TR6 is the way to go IMO gapped at .036-.038" The 7's don't like lower boost and or a cold motor, they also surge a little at while cruising at low to moderate throttle settings. They come into their own when pushing higher power such as 16# boost and above.

Cool Bob thanks for the info, if they dont like a cold motor then the TR6's is wat iam gonna pick up.

Yup! i got over zealous in thinking i was going to make gobs of boost, now i have teh BR7 and they surge bad... time to yank them out for some TR6s...
