Perrin FMIC Red Boost Tubes and Black Couplers Subaru WRX 2015-2021 | PSP-ITR-437-2RD/BK

Fitment: This product fits 2015 - 2021 Subaru WRX models. Features: The core is not included and can be bought separately. The boost tubes have a wrinkle powder - coat red finish. They are made of mandrel - bent aluminum for great weight reduction. Each tube has an over - sized beaded end to keep the hose clamps and couplers well - connected and sealed. Hose clamps are provided, and there's an aluminum coolant reservoir catch can. You'll also get installation instructions and a 5 - year manufacturer warranty. These PERRIN boost tubes are CNC mandrel - bent from aluminum tubing. We've chosen the smoothest and shortest path for air to flow to and from the intercooler. Right from the turbo, a smooth offset coupler sends the hot - side air charge to a well - matched 2.25” boost tube. This 2.25' tubing offers smooth, clean, and obstruction - free routing and can handle more WHP than most turbos can produce. The air charge then goes through the engine bay next to the battery, behind the radiator, and to the intercooler. The cold - side boost tubes are placed high in the engine compartment to avoid all turbo and intake combinations as they lead to the throttle body through the engine bay.

Using your Perrin boost tubes is straightforward. First, refer to the installation instructions that come with the product. Make sure all the parts are in good condition before starting the installation. When installing, pay attention to the routing of the tubes as described in the product description. Connect the tubes securely using the provided hose clamps. Note that the core is sold separately, so you'll need to purchase and install it if you haven't already. For maintenance, regularly check the connections of the tubes and clamps to ensure they are tight and sealed. Inspect the aluminum parts for any signs of damage or corrosion. If you notice any issues, contact the manufacturer as the product comes with a 5 - year warranty.
