Kartboy Aluminum Crank Pulley Subaru WRX / STI / Legacy GT / Forester XT / Baja Turbo EJ Models
One of the benefits of a Subaru boxer engine is that they respond well to lightweight crank pulleys. Kartboy’s crank pulley is a great option for you WRX/STI owners. Think of it as having a lightweight flywheel, you’re going to reduce the rotational mass and strain on the engine.
