NGK Nitrous! 1998 ws6 stock ls1 with headers slp lid and ls6 intake with 100-150 nx plate kit...
right now the tr5s are in the car which was before the spray.
now with the spray which should be used the br6ef or the br7ef
i know that some say br7ef but dont want it to be too cold because the car is 75 percent weekend car.
And what gap?

I had the same concerns as you. Car was originally tuned for spray on tr6s because I didn't know any better. Now I have a kit on the car again I started with br7s at .034~. I've made no changes to the tune at all and I can't feel a damn difference except for feeling a lot more comfortable when the kit is on. Just put the colder plug in.

BR7EF's at .030... Usually most of the LS cars will do fine on these plugs for driving and idling, however some cars may need an adjustment in the tune to compensate for them.
