Overview:

The HPS Silicone Air Intake Hose Kit is a high-quality replacement for the restrictive stock rubber intake tube found on Toyota GR86 and Subaru BRZ models from 2022 to 2026. Designed for enthusiasts seeking improved throttle response and overall engine performance, this kit delivers smoother airflow and enhanced durability. It is an ideal upgrade for daily drivers and performance-minded owners who want to optimize their vehicle’s intake system without complicated modifications.

By replacing the OEM rubber hose with a reinforced silicone alternative, this kit helps prevent common issues such as vacuum leaks and bad idling caused by cracked or collapsed factory hoses. It also integrates seamlessly with the factory fresh air scoop and air box to ensure the engine receives cooler, denser air for better combustion.

Key Features:

This silicone air intake hose kit offers several technical advantages that enhance your vehicle’s performance and reliability:

• Constructed from high-temperature 4-ply reinforced silicone, capable of withstanding up to 350°F to resist heat soak and maintain optimal 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 optimize airflow and improve throttle response.
• Includes industrial-grade 100% stainless steel embossed hose clamps for secure, long-lasting fitment even under harsh driving conditions.
• Designed to integrate with the factory fresh air scoop and air box, directing cool air efficiently to the engine.
• Prevents or resolves vacuum leaks and bad idling issues commonly caused by damaged OEM rubber air injection hoses.
• Compatible with OEM part numbers SU003-09557 and 46019CC000 for direct replacement.
• No cutting, drilling, or special tuning required for installation.

Construction & Design:

The intake hose is engineered using a high-temperature reinforced silicone material that provides superior heat resistance and durability compared to the original rubber hose. Its 4-ply construction ensures flexibility while maintaining structural integrity under engine bay heat and pressure. The kit retains the use of the factory air filter housing, minimizing the number of parts to replace and simplifying installation. The included stainless steel clamps are embossed for added strength and corrosion resistance, ensuring a secure seal that withstands vibration and road conditions.

Performance & Sound
