COBB Aluminum Charge Pipe Kit WRX 2022-2026 | 746110

COBB part 746110 replaces the factory turbo-to-intercooler charge pipe on the 2022-2026 Subaru WRX. The 6061-aluminum tube transitions from 2.5 inches at the turbo side to 2.75 inches at the intercooler side and uses a billet factory-style retaining clip plus a five-ply silicone coupler. It fits manual and CVT WRX variants and is also sold for several FA24-powered Subaru applications, but this catalog record is scoped to the VB WRX. COBB states the pipe can be used on the stock calibration and with its compatible off-the-shelf maps; a Stage 2 calibration can take fuller advantage when the pipe is combined with the rest of the required hardware. Confirm that both couplers are fully seated and leak-free after installation.
