Chris Randazzo
The perfect little accessory upgrade for your alternator

I’ve already experienced the benefit of a resurfaced flywheel and a lightweight crank pulley, and this matching component will help me achieve even better throttle response for my Impreza.
Nothing short of high-quality when it comes to Perrin products.
