Process West FA Intake Manifold Polished Subaru WRX 2015-2021 | PWIM007

For your Subaru WRX from 2015 to 2021, here's the amazing Process West FA Intake Manifold. It features a durable billet aluminum plenum that offers more volumetric efficiency. This intake manifold is perfect for those who want to handle more power and boost. The factory intake manifold is made of plastic. While it's good for bolt - ons, it can limit the flow for high - power builds with larger turbochargers. Highlights include: Durable billet aluminum plenum construction, cast aluminum large - bore runners, computer - designed and tested internal plenum porting. It provides a larger volume and greater runner capacity for optimal cylinder filling. With a polished finish and strong tig - welds that can handle over 100 psi of boost. The plenum is designed to boost low and mid - range torque and open up power at higher revs. Ideal for high - power builds that exceed the factory manifold's limits, suitable for street cars, drag cars, race cars, and rally cars. It gives your engine bay a clean and custom look and won't trigger a CEL, so no tuning is required.

Using this Process West intake manifold is easy. First, make sure your Subaru WRX is turned off and cooled down. Remove the old intake manifold carefully following your vehicle's repair manual. Then, install the new Process West intake manifold in its place, making sure all connections are secure. As for maintenance, keep it clean by wiping it down regularly with a soft cloth. Check the tig - welds and connections periodically for any signs of wear or damage. There's no need for any special tuning, and it won't trigger a CEL, so you can enjoy the improved performance with peace of mind.
