The Process West PWCAI10 replaces the factory VB WRX intake with a black mandrel-bent aluminum tube, enclosed airbox, K&N filter, and machined mount for the original airflow meter. It retains the factory intake duct and installs without cutting or permanent body modification. Process West lists 2022+ WRX fitment, while its US retailer lists 2022–2026 manual and automatic applications. The manufacturer's installation guide contains an important calibration warning: the intake can create a lean condition and the ECU must be recalibrated for the airflow change. This is therefore a tune-required intake, not a stock-calibration bolt-on. Installation includes lower-liner access, MAF transfer, an extension harness, and airbox alignment.
