57-2122

Overview:

The HPS Silicone Air Intake Hose Kit is a high-quality replacement for the restrictive stock rubber intake tube found on Subaru BRZ and Toyota GR86 models from 2022 to 2026. Designed for enthusiasts seeking improved throttle response and overall engine performance, this kit enhances airflow while providing excellent heat resistance and durability. It is ideal for daily drivers and performance-minded owners who want a reliable upgrade without complicated installation or tuning.

By optimizing the intake path and integrating seamlessly with the factory fresh air scoop and air box, this hose kit helps deliver cooler air to your engine, supporting better combustion and power output. It also addresses common issues such as vacuum leaks and bad idling caused by cracked or collapsed OEM rubber hoses.

Key Features:

This silicone air intake hose kit offers several technical advantages over the stock component:

• Constructed from high-temperature 4-ply reinforced silicone, capable of withstanding up to 350°F to resist heat soak and maintain cooler intake air temperatures.
• Delivers dyno-proven performance gains of approximately 4 horsepower and 3.5 lb-ft of torque without requiring any engine retuning.
• Replaces the stock restrictive rubber intake tube to provide smoother, unrestricted airflow for improved throttle response and engine efficiency.
• Integrates directly with the factory fresh air scoop and air box to channel cool air effectively to the engine.
• Includes industrial-grade 100% stainless steel embossed hose clamps designed to withstand harsh road conditions and ensure a secure fit.
• Prevents or resolves vacuum leaks and bad idling issues commonly caused by damaged or collapsed OEM rubber air injection hoses.
• Compatible with OEM part numbers SU003-09557 and 46019CC000 for direct fitment.
• Maintains use of the stock air filter housing, minimizing parts changes and simplifying installation.

Construction & Design:

The intake hose is engineered from premium reinforced silicone material, providing superior heat resistance and long-lasting durability compared to the factory rubber hose. Its 4-ply construction ensures structural integrity under high temperatures and prevents collapse or cracking over time. The hose’s design optimizes airflow by reducing turbulence and restriction, contributing to smoother engine breathing and improved throttle response.

HPS includes heavy-duty stainless steel embossed clamps that secure the hose firmly in place, ensuring reliability even under demanding driving conditions. The kit’s design allows it to integrate perfectly with the factory fresh air scoop and air box, maintaining the OEM cooling path for intake air.

Performance & Sound

• Provides a measurable increase of 4 horsepower and 3.5 lb-ft of torque as verified on the dyno.
• Improves throttle response by delivering more consistent and unrestricted airflow to the engine.
• Helps reduce intake air temperatures by preventing heat soak, supporting sustained performance gains.

Installation & Fitment:
