Product Description

The PERRIN PSP-PCV-110BK is a direct replacement PCV hose engineered specifically for the 2022-2025 Subaru WRX, addressing a common weak point in the factory positive crankcase ventilation system. The OEM rubber hose lacks reinforcement and is prone to cracking under the combined stress of manifold vacuum and boost pressure, which can lead to boost leaks, check engine lights, and reduced engine power over time.

PERRIN's replacement is built from reinforced silicone specifically engineered to withstand these demanding conditions without failure, and it adds a fluorosilicone inner layer that resists oil and fuel vapor permeation - a detail the OEM hose lacks, which contributes to long-term deterioration and unwanted odors. The result is a hose that maintains proper PCV system function reliably under boost, helping preserve consistent engine performance.

This hose suits WRX owners who want to proactively address a known factory failure point, whether the OEM hose has already begun showing signs of cracking or as a preventative upgrade before problems start. Beyond durability, the clean black finish gives the engine bay a slightly more finished look compared to the factory rubber hose, and its OEM-style fitment keeps installation straightforward.
