I just got a good deal on an MSD ignition setup. Now I've got a few questions. My ignition will be as follows:

MSD Pro billet distributor, p/n 84697
MSD Flying Magnet crank trigger, p/n 8600 or 8615
<A HREF="http://store.summitracing.com/default.asp?target=esearch.asp&N=100&Ntk=PartSearch&Ntt=msd-6600&x=0&y=0">MSD 6-HVC Ignition box, p/n 6600</A>
<A HREF="http://store.summitracing.com/default.asp?target=esearch.asp&N=100&Ntk=PartSearch&Ntt=msd-8250&x=0&y=0">MSD HVC coil, p/n 8250</A>
MSD Soft touch rev control, p/n 8738

I'm pretty sure I'll have more voltage to the plugs than stock, I'm not sure about the numbers that the Blaster series coils put out. That being said, I want to give the plugs with the shortened strap a try. Anyone have any experience with these? Any brands to try? Avoid? Basically, I'm looking for plug recommendations.

Also, has anyone tried the Moroso Ultra 40 plug wires? At 40 ohms per foot of resistance, I'm pretty impressed by how they look.

This is a high rpm road racing engine.

 

The plug gap voltage will only be as high as it needs to be to create an ion trail between the electrodes. The spark current is what you'll likely be increasing.

In my limited experience, a daily driver will do very well with Champion plugs. If you have a wasted spark system, dual platinum electrodes are the way to go.

However, for a higher demand application that will subject the plug to a lot of heat and pressure, it's tough to beat NGK. Their electrodes are about as good as Champion, and the seals are as good. But they have an excellent ceramics development program, and the insulator is probably the biggest factor in plug life and performance over the long haul in high demand applications. As long as you can find one that has the correct nose projection and gap placement in your chambers, it's worth trying.

Anything in a consumer package that says "Bosch" on it is probably about the lowest overall quality, right next to Autolite and Sure-Fire.

Just my 2¢
