Don't waste your time with the LS1 coils, they are miserable little failures.

I BELIEVE that's the one with the auto-discharge, so setting it up properly in the ecu is key.... just ask the legions of RX8 owners that blew their engines while cranking it with the BHR upgrade.

CDI DO NOT create "electrical noise" unless it is a very poor install or fitted by someone who has no idea of CDI systems

But there are times when a CDI is just not needed. Hell, I picked up a whopping 3rwhp when I added a $1200 M&W box. Is that REALLY worth it? NO

That's becuase MSD's suck.... it's short for My Spark Died. Your car is probably at such a low BHP rating that a CDI ignition system wouldn't make a difference. It's like putting a triple carbon disc on a stock n/a car.
