Fitment Information
- Subaru Impreza (1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025)
Specs & Features
- Material: 6061-T6 billet aluminum body + 4130-steel hub (on large-hub variants)
- Finish Options / SKUs: Anodized - available in Black (104BK), Blue (104BL), Red (104RD)
- Weight / Mass Reduction: Pulley is ~ 1 lb lighter than OEM (some sellers say “just 2 lbs total”) vs heavier stock pulley - this reduces the rotational mass on the crankshaft/drive belts.
- Effect on Performance: Faster throttle response, quicker rev-ups, improved engine responsiveness, and - in some cases - slight gains in horsepower/torque due to reduced parasitic drag.
- Belt & Accessory Compatibility: Machined grooves / correct belt path; designed to work with OEM (and aftermarket) belt systems; no lost compatibility for alternator/AC/etc (so long as correct hub version).
- Installation: Direct replacement of stock pulley + hub; roughly 10–15 min install time (with proper tools, torque-wrench for crank bolt)
- Tuning Requirement: None strictly required - works with stock ECU settings.
