    Default Ignition [Expired Topic]

    Does anyone have experience with a msd multi spark ignition control box like the 6a or comparable products? Also, to maximize the effect, what kind of distributor, spark plugs and wires are the best with that? Supposedly it improves engine power, increases gas mileage, lets the engine live longer, improve emissions etc. etc. How big is this effect really?

    The spark that comes out of an MSD set up is incredible. I never got any measurable mileage increase, but I still use them. The stock distributor will do. Just get a high quality cap and rotor, a good coil and BIG 9mm plug wires and you're set to go. Spark plugs don't matter with an MSD. I swear you could tear the ground electrode off the plug and the MSD would just spark to the top of the piston!

    Wow, that sounds like a real improvement over stock. So much more spark should at least improve power and emissions. I'll look for an msd 6 on ebay.
