Just wondering what plugs are you guys running on 4port 13B's. Namely hybrids(12A plates with SE rotors and housings). Right now I'm using 2nd gen plugs with my FC coil/MSD direct fire ignition on my hybrid.


Thanks, Ed

 

Stock 2nd gen plugs work fine with 2nd gen type ignition systems.I still use them on my 300HP S5 streetport TII powerplant.
For my old carb'd 12A and 13B 4 ports with a Yaw carb,I used the Denso W25EDR14 plugs.They held up to the MSD direct fire/Blaster coil system, much better than NGK's.

 

those are fine for daily driving. I use either the B10EV's or Autolite race plugs - these will allow you to rev fast.
