PERRIN 22-25 Subaru WRX / 21-25 Crosstrek / 20-25 LGT/OBXT/FXT Lightweight Water Pump Pulley - Black

If you're looking to shave a little weight off your engine's rotating assembly, this Perrin lightweight water pump pulley for your Subaru WRX, Crosstrek, or other compatible models is a solid option. By reducing the mass of the pulley, you're lessening the load on the engine, which can lead to a slightly improved throttle response. It's a straightforward way to make a small but noticeable change to how your engine feels under acceleration.

This pulley is made from well-built aluminum, which is significantly lighter than the stock cast iron or steel pulley. Perrin machines these from a solid block of aluminum, ensuring a strong and durable part that's built to last. The black anodized finish not only looks sharp under the hood but also helps protect the aluminum from corrosion. It's designed to fit right in place of your factory water pump pulley, making installation a breeze for anyone comfortable working around the engine bay.

When you're installing this, remember that while it's a lightweight part, it still needs to effectively circulate coolant. Make sure your cooling system is in good shape before you swap it out. This pulley is a popular choice for Subaru owners looking for simple, effective modifications that enhance the driving experience without requiring complex tuning.
