BLOX Racing 2015-2021 Subaru WRX Blue Charge Pipe Kit
The BLOX Racing Blue Charge Pipe Kit replaces the factory plastic charge pipe on 2015-2021 Subaru WRX models with lightweight mandrel-bent aluminum tubing. This direct bolt-on upgrade increases inner diameter from stock 2 inches to 2.75 inches for smoother airflow and faster turbo response. Gain noticeable throttle response and horsepower while adding a vibrant blue finish to your engine bay. Reinforced high-temperature 4-ply silicone couplers and stainless steel T-bolt clamps ensure airtight, vibration-resistant connections. Ideal for stock, tuned, or high-boost WRX builds seeking improved performance, quicker spool, and aggressive underhood style.
Key Features & Benefits
