ZZPerformance has long been considered the leader in M90 blower performance. This is our Gen 3 M90 ported blower case which has been inspected, ultrasonic cleaned, CNC ported, and the needle bearings have been replaced. We have spent countless hours determining the optimal blower case outlet design using our Supercharger tester. We have tested all of the most common blower outlet designs and this is the best performing one.
Everybody knows we run out of stock of these all the time, so get them before we run out again! Fortunately ZZPerformance now offers a cost effective solution. Uses factory mounting, so all the factory bolts and gaskets can be re-used. The Powerlog and Ported rear manifold will support up to around whp, but for a goal higher than that, we highly recommend our Stainless headers. I also wanted to post that I just went through my 1st full tank of gas after the plog yes I drive a lot and I have picked up a few MPG as well.
