High Output Impeller Upgrade

Upgrade your factory impeller with this High Output Impeller to increase boost by 2-3 PSI (on average) and increase your power band, a typical power band for these blowers starts around 3000 RPM's you will start to see the power kick in around 2500 RPM's. This upgrade will cause NO extra stress on your unit and wont cause you to need to rebuild your unit faster like you experience with a pulley upgrade.

**NOTE: Replacing a hard part like this WILL require shimming your unit. Professional installation recommended!**
