Is it reasonable to run FB leading plugs with 2GCDFIS?
Thinking of doing 2GCDFIS, but new FB plugs already went in recently. Would be kind of a waste to buy FC leading set just to accommodate the FC coil. Is there enough difference between the FB and FC to warrant an extra purchase?

I had the stock FB plugs in it, and went to the 2nd gen plugs, never felt a difference.

I use FC plugs with mine, and seems to work great. Maybe a slight improvement...

I use FC plugs in both my 12A with stock ignition, and the SE with DIY direct fire.

I run stock 12a plugs, and that's what I've had the best results with. The FC plugs are too shrouded and inhibit the flame front.
