Perrin Turbo Inlet Hose Black 2015-2021 WRX / 2014-2018 Forester XT

Unlock the full potential of your turbocharged Subaru with the Perrin Turbo Inlet Hose. Designed to replace the restrictive and failure-prone factory hose, this high-performance upgrade improves airflow, throttle response, and overall engine performance.

Crafted from multi-layered, fiber-reinforced silicone, the Perrin Turbo Inlet Hose resists collapse under high boost pressure while maintaining superior heat resistance and durability. Its smooth internal surface reduces turbulence, allowing your turbocharger to spool faster and operate more efficiently.

Key Features:

• Optimized Airflow: Smooth interior walls and increased diameter promote better airflow to the turbo. The Perrin Turbo Inlet hose has a 3.0" internal diameter compared to 2.6" found in the OEM part.

• Durable Construction: 5-ply silicone reinforced with heat-resistant fibers ensures long-lasting performance under extreme engine bay temperatures.

• OEM Fitment: Designed for a perfect fit with stock or aftermarket turbos; includes CNC-machined aluminum fittings for a secure, leak-free installation.

• Performance Gains: Improved throttle response and potential horsepower increases with supporting mods. The Perrin turbo inlet hose is much smoother than the OEM part, with more gradual bends toward the turbo making for less restriction leading to increase horsepower and improved acceleration.

• Wire Reinforcement: Reinforced with stainless steel support wire embedded within the silicone layers, the support adds rigidity to the hose and prevents collapses. 

Notes:

• Fits these aftermarket cold air intakes with no modifications: PERRIN, AEM, K&N, Mishimoto, Injen SP
• Canadian models with aluminum inlet will require additional 1/2" to 1/2" connector for coolant hose bypass
