[Fot] 1300 Spitfire Spark Plug Survey

[Jerry Barker]

N60Y is the plug we ran for years, if you can find them they will work fine. Two things to look for is that the pistons to plug electrode clearance can be a problem, you need rubble plugs washers and the electrode must be up or away from the piston. The extended trip of the plug will help horse power.

A survey if you will, for 1300 Spitfire racers.
What spark plug and why? I'm running a 12.5:1 compression ratio. My race shop guy told me my NOS Champion N60Y were "crap".
Thoughts?
Thanks,
