spark plugs

[yukon yamaha]

Has any one run a NGK CR9EKB plug in their nytro? I have seen a few guys run CR10EK plugs but they were are boosted sleds,
So if any one has and experince with these plugs i would love to know how you liked them and if they were worth putting in

The only thing that will show a gain is the CR10EK plugs, I've been on the dyno for days trying other combinations of plugs to no avail. The "EKB" series plugs will not fit in the FX Nytro due to the terminal cap being built into the plug.

have you been testing on a stock machine or was it boosted?

Funny as I just changed my plugs to CR10EK in the XTX about 15 minutes ago. Thanks Allen

The spark plug testing I have done is on a stock machine.
