Cobb Subaru Aluminum Charge Pipe Kit - 2022+ Subaru WRX

Replace the factory plastic charge pipe on your FA24-powered WRX with the COBB Aluminum Charge Pipe Kit to unlock better airflow, improved reliability, and a cleaner under-hood look. Designed to work with the OEM top-mount intercooler, this upgraded charge pipe smooths the path from the turbocharger outlet to the intercooler while retaining full compatibility with the stock airbox and factory calibration.

Factory plastic piping can introduce turbulence and is prone to fatigue and cracking over time as it is constantly heat cycled. COBB solves this with CNC-radiused 6061 aluminum tubing, an integrated billet transition, and a robust turbo-side adapter that securely locks into the compressor housing.

Key Features

• CNC-Radiused 6061 Aluminum Tubing: Smooth, rigid charge path that resists heat-related degradation.
• Optimized Diameter Transition: 2.5" at the lower section transitioning to 2.75" at the intercooler connection via an integrated billet adapter for increased flow and proper clearance.
• Wrinkle Black Powder Coat: Durable, heat-resistant finish that delivers a subtle, OEM+ aesthetic.
• Bespoke Machined Retaining Clip: Anodized clip with ball detent positively locks the pipe to the turbocharger housing.
• 5-Ply Silicone Coupler: High-quality coupler at the intercooler side for a straightforward, leak-free installation.
• Tune-Friendly: Fully compatible with the stock calibration and COBB Off-The-Shelf (OTS) maps.
