how about MSD

[targa]

i was watching one of the many car shows on the télé the other day and they were talking about MSD boxes

they said it increases fuel economy, and i was wondering about putting it on my car, is it worth it? would it really help anything?

i will try to find some good rescorces and link them

MSD makes great performing systems, although I prefer to not have that ugly box hangin around my engine compartment (which is why I use the Pertronix system, hides in the distributor cap so nobody's the wiser). Basically the point is that it can deliver a hotter spark with more precise timing than the stock system, so it can in theory promote a more complete combustion and allow you to really dial in your ignition timing for more power.
