Product Description

The Perrin Performance PSP-INT-421RD Turbo Inlet Hose is designed to enhance the performance of your 2008-2014 Subaru WRX, 2005-2009 Subaru Legacy GT, or 2009-2012 Subaru Forester XT equipped with the 2.5L turbocharged engine. By increasing the inner diameter to 2.4 inches and utilizing a multi-layer heat-resistant silicone construction, this inlet hose significantly improves airflow to the turbocharger. The stainless steel support wire embedded within the silicone layers adds rigidity and prevents collapse under high boost conditions.

The included glass-filled reinforced nylon coupler ensures a smooth transition from the intake to the turbo inlet hose, reducing turbulence and improving throttle response. The plug-and-play crankcase vent connector maintains proper MAF alignment, preventing common issues such as engine bogging and check engine lights. Available in a vibrant red finish, this inlet hose not only boosts performance but also adds a stylish touch to your engine bay.
