Perrin Performance
PERRIN Turbo Inlet Hose for 2008-2014 Subaru Impreza WRX - Black (PSP-INT-421BK)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2008-2014 Subaru Impreza WRX, WRX Limited, and WRX Premium.
The PERRIN Turbo Inlet Hose (PSP-INT-421BK) is a high-performance upgrade designed to replace the restrictive, corrugated factory rubber inlet. By providing a larger, smoother internal diameter, this hose increases airflow to the turbocharger, improving throttle response and power delivery throughout the RPM range.
Built for durability in high-heat environments, the hose is constructed from multi-layer reinforced silicone. Unlike the standard OEM part, the PERRIN inlet features an internal wire reinforcement that prevents the hose from collapsing under the high vacuum levels created by increased boost or larger aftermarket turbochargers.
- High-flow design increases air volume to the turbocharger
- Multi-layer silicone construction for superior heat resistance
- Internal wire reinforcement prevents hose collapse under vacuum
- Smooth internal bore reduces air turbulence
- Corrosion-resistant black finish for a clean engine bay look
- Manufacturer Part Number: PSP-INT-421BK
