Cobb 15-21 Subaru WRX FMIC Cold Pipe Kit

The 3-inch diameter mandrel-bent aluminum tubing in this COBB cold pipe kit is a key factor in its improved airflow for your 2015-2021 Subaru WRX. This larger diameter, combined with smooth internal bends, helps reduce restriction between your intercooler and throttle body. This means your engine can receive cooler, denser air more efficiently, which is crucial for maintaining consistent power, especially when you're pushing your car hard.

COBB built this kit using well-made aluminum tubing that's designed to handle the boost pressures common in modified WRXs. The kit replaces the factory rubber and plastic piping, which can expand under pressure and heat, potentially leading to boost leaks. By swapping to these solid aluminum pipes, you get a more reliable connection that helps maintain consistent boost levels. The kit includes all the necessary silicone couplers and T-bolt clamps for a secure installation, ensuring a leak-free seal.

This kit is a popular choice for WRX owners looking to optimize their front-mount intercooler (FMIC) setup. While it's designed as a direct replacement for the stock piping, it's important to note that this part is not CARB approved and cannot be shipped to California. For the best results, consider pairing it with other COBB performance parts designed for your WRX.
