What spark plugs for stage 2?

Hey guys,

Im looking for some opinion on what plugs to run in my Aluminum headed stage 2 motor. I am running a MSD ignition, 11:1 and burn 100 octane all the time.

NGK BP6ES or BP7ES. 7 is colder than 6. I run BP8ES in my 13:1 motor.

 

Thanks

Have never run NGK in a car, just motorcycles. Ill give it a try and see.

Thanks

Dennis

 

John Zerucha and I have had perfect luck with the NGK V-Power.....
Stock# at the parts store is 4554 which is a R5671A-8 if memory serves correct.

 

I love the V-power plugs. I don't have Aluminum heads (yet), but I use the NGK UR-5 in my irons, and have had real good luck with them. :TU:

NGK highly recommended.

Not looking forward to the part #'s for aluminum heads :eek2: UR-5 is real easy to remember. :grin:

 

Gary,
What gap do you run on those?

 

Think I was using about .040

 

Hi Dennis,
I run the Autolite AR3934. It's a nice racing plug :3gears: . You now have a few to choose from. I just wanted to put my 2cents in :Comp:
