I like to know the opinion of the people in this forum:
What is the gap you use in the NGK BKR7E spark plugs, for a Turbo application (14.5 psi low boost and 18.5 psi hight boost with a 35Hp N2O shot) in a B18C1 with standard ignition and 95 octane fuel?
I use the NGK BKR7E by recomendation of a friend-tuner in Florida (USA), for my application 8's are very cold... in example in this moment I'm tuning the low side of my maps because the sparks are very black and the car run very rich...
The 7s are recommended from Honda for a STOCK b16 in hot climates or 'fast driving' conditions. How come the 8s be too cold for a b18 with 18 psi of boost and nitrous?
sorry, but those are absolutely the wrong plugs to run. 5671A-8 or bkr8eix are much closer to your application with a gap of .028". the first number will require frequent replacement (3k miles) while the second are rather expensive ($56). if you have ignition problems at that gap you need to upgrade your ignition. if the plugs are black you need to address the tune first.
