What spark plugs for a 2.4 CIS with MSD 6200?
I have a 73.5 911 2.4 with CIS injection - and I've replaced the CD ignition with a MSD 6200 and Blaster Coil and new Magacor wires (and new cap & rotor). It starts fine, runs well when cool - but has the engine gets hotter it starts to break down a bit on acceleration. I thought I would check all my ignition components first, and wondered what I should be using for plugs and a what gap using the MSD (I currently have .030). Thanks for your help!

I would try a BP6ES with a .45 gap. .30 is not enough for an MSD in my experience.

+1. Engine runs smoother with .45".

Yep, just run the cheap copper plugs, stay away from the trendy ones, MSD will eat them up.
