HPS Performance Silicone Air Intake Kit Post MAF Hose for 2012-21 BRZ

The HPS 4-Ply High Temperature Reinforced Silicone Air Intake Hose Kit (Part #57-1231) is designed for the 2013-2021 Subaru BRZ 2.0L, replacing the restrictive factory rubber intake hose and eliminating the stock sound tube. Built to meet or exceed OEM specifications, this upgraded silicone hose is rated for temperatures up to 350°F, offering improved durability and resistance to heat soak.

Without requiring tuning or additional modifications, this kit delivers dyno-proven gains of +1.4 WHP and +1.2 ft-lbs of torque, while improving throttle response and helping the factory airbox perform more efficiently. Installation is straightforward, and the kit is designed not to trigger a CEL.

In addition to performance benefits, this silicone intake hose is an excellent replacement for worn or damaged OEM rubber tubing, helping prevent or fix common issues such as vacuum leaks, collapsed hoses, and rough or unstable idling.
