Cobb 15-18 Subaru WRX Top Mount Intercooler Kit - Black
SKU: C005 B42400-BK
Moderate — 2–4 hours
Overview
Installation involves replacing the factory intercooler and plastic end tanks, which are prone to failure. The COBB kit includes a heavy-duty mounting bracket and a bushing to isolate vibrations. The charge pipe transitions from 2" to 2.5" to allow for increased flow while maintaining clearance for aftermarket radiators. The kit is compatible with both the factory bypass valve and the COBB LF BPV.
