Perrin Crank Pulley WRX 2015-2018 / Scion FR-S 2013-2016 / Subaru BRZ 2013-2018/ Impreza 2012-2013
The PERRIN Performance Crank Pulley for the WRX / BRZ / Impreza / Scion FR-S weighs just 1.2 lbs, which is 3.7 pounds lighter than the stock OEM crank pulley. This reduction in weight from the crank shaft is equal to removing more than 100 lbs of vehicle weight! Throttle response, horsepower and torque are all increased with this easy to install part.Does not fit 2019 WRX.

Another great product from Perrin. The quality and finish is perfect. Gives the engine bay a nice touch. I was amazed at the weight difference vs the stock crank pulley. Directions are straight forward. Install took about 30 minutes . Noticeable throttle response change with this part installed.
I installed this with the water pump pulley and I was definitely able to notice a gain in horsepower as well as torque. It also dresses the engine up a bit which is a bonus
