HPS Reinforced Silicone Post MAF Air Intake Hose Kit

2013–2016 Subaru BRZ / 2013–2016 Scion FR-S / 2017–2020 Toyota 86

57-1231-BLUE

Overview:

The HPS Reinforced Silicone Post MAF Air Intake Hose Kit is a high-quality upgrade designed to replace the restrictive stock OEM hose found on Subaru BRZ, Scion FR-S, and Toyota 86 models within the specified years. Crafted from high-temperature 4-ply reinforced silicone, this hose improves airflow efficiency and reduces heat soak, enhancing your vehicle’s overall performance without requiring any tuning adjustments.

This kit is ideal for enthusiasts seeking a reliable, durable solution to optimize their air intake system. By eliminating the factory sound tube, it also streamlines the intake path, contributing to better throttle response and a cleaner engine bay setup.

Key Features:

Engineered with performance and durability in mind, this post MAF hose offers several benefits:

• Constructed from high-temperature 4-ply reinforced silicone for superior heat resistance and longevity.
• Replaces the OEM restrictive hose to improve airflow and reduce intake air temperatures.
• Deletes the stock sound tube for a more direct airflow path and simplified installation.
• Dyno-proven performance gains of approximately +1.4 wheel horsepower and +1.2 ft-lbs of torque without requiring re-tuning.
• Precision fitment ensures seamless integration with factory components on Subaru BRZ (2013–2016), Scion FR-S (2013–2016), and Toyota 86 (2017–2020).
• Durable blue silicone construction adds a clean, performance-oriented aesthetic under the hood.
• Helps reduce heat soak to maintain cooler intake air temperatures for improved engine efficiency.

Construction & Design:

This hose is crafted from premium high-temperature silicone reinforced with four layers of durable fabric, providing excellent resistance to heat, pressure, and wear. The reinforced design ensures the hose maintains its shape and integrity under demanding conditions, preventing collapse or deformation that can restrict airflow.

The smooth interior surface promotes laminar airflow, reducing turbulence and improving throttle response. By deleting the factory sound tube, the hose offers a more direct and less restrictive air path, which contributes to enhanced engine breathing and performance.

Performance & Sound

• Improves airflow efficiency compared to the stock intake hose, supporting better engine performance.
• Reduces heat soak, helping to maintain cooler intake air temperatures for more consistent power delivery.
• Delivers a subtle improvement in intake sound by removing the restrictive sound tube, enhancing the driving experience without excessive noise.
• Dyno-tested gains of +1.4 wheel horsepower and +1.2 ft-lbs of torque achieved without any ECU tuning.

Installation & Fitment:

The HPS post MAF hose is designed as a direct bolt-on replacement for the factory hose on Subaru BRZ (2013–2016), Scion FR-S (2013–2016), and Toyota 86 (2017–2020). It uses existing mounting points and OEM air inlet connections for a straightforward installation process.

No cutting, drilling, or special tuning is required, making it an easy upgrade for enthusiasts and professional installers alike.

What's Included:

• High-temperature 4-ply reinforced silicone post MAF air intake hose
• All necessary clamps and hardware for installation
• Installation instructions

Ideal For:

• Performance enthusiasts looking to improve airflow and throttle response on their Subaru BRZ, Scion FR-S, or Toyota 86.
• Daily drivers seeking a durable, heat-resistant upgrade to the factory intake hose.
• Track and spirited drivers who want proven power gains without ECU tuning.
• Anyone aiming to reduce intake heat soak and improve engine efficiency.
