Hi,i personally like ngk. However, many of the other plugs work well with your application......finding the right heat range is key! Alot of trial and error......make youself some good notes as you proceed. Best of luck and have a blessed week. Jim

cross-over Was going to get the br7ef's today but no one had them in stock....they did have some cross-over brands like motercaft,autolite,fram ect. what would be the next best brand becides the NGK's
I know others have given you their input and even said use a 7 plug. I think you are on the right path with the BR6EF and I have had great luck with them. I truly believe if you use a 7 heat range you will be fouling plugs for no reason. It is my opinion that the 6 is better for your engine if the mod’s that you have listed in your sig are the only thing done to your engine.
If I understand correctly you are supposed to reduce the gap from factory specified gap by .004 for every 50 HP you add this also includes what HP you have added NA. Example if you added 50 HP NA and 100 HP on nitrous you should reduce the gap from .060 - .012 = .048 gap (3 ea. X .004 = .012).
The information I have been using also said it is better to be safe and go a little narrower than wide since the gap tends to gradually widen as the plugs age so just in case in the example above they would suggest to use .044 to .046 as the gap!
I would think that a .035 gap is too tight for you application! There does not appear to me to be enough evidence to warrant a .035 gap for your application.
I hope this helps!

Going BR6EF Doubt I'll be running anything over 100 shot @ least till I get some taller gears,(4.10's now) So I will go w/ the br6's but 48 seems like awide gap
