Benefits of Upgrading
- Increased Horsepower: Expect gains of 20-30 horsepower with this upgrade.
- Improved Torque: Enhanced torque delivery for a more responsive throttle.
- Better Throttle Response: Quicker boost onset for a more engaging driving experience.
Tools Required for Installation
- Socket set (including 8mm, 10mm, and 13mm sockets)
- Torque wrench
- Ratchet and extensions
- Flathead and Phillips screwdrivers
- Puller tool for the supercharger pulley
