NGK or BOSCH?
 

Hi folks,

Do you think it makes a difference using NGK or BOSCH Spark plugs?

Either should be fine but I trust NGK for plugs.

I agree that either should be fine, but I prefer the Bosch platinum's. I ran 12psi and 125hp nitrous and they held up fine. Every time I took them out they had the perfect tan color.

I prefer plugs that have shielding around the electrode all the way to the top. Spark jumps from the edge of the electrode, and the insulation helps keep the electrode from wearing down and getting rounded on the end.
