Perrin Performance
PERRIN 02-05 Subaru WRX / 04-06 STI / 93-11 Impreza Lightweight Alternator Pulley - Red
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1993-2011 Subaru Impreza, WRX, and STI models. The PERRIN Lightweight Alternator Pulley is designed to reduce rotational mass on the engine's crank, allowing for faster revving and improved throttle response by lowering the moment of inertia. This component replaces the heavy factory steel pulley with a precision-engineered alternative that maintains standard charging system speeds.
- Precision CNC machined from 6061-T6 billet aluminum
- Red anodized finish for maximum corrosion resistance and engine bay aesthetics
- Significantly lighter than the OEM steel pulley to reduce parasitic drag
- Direct bolt-on installation using factory mounting hardware
- Manufacturer Part Number: PSP-ENG-118RD
