HPS Reinforced Silicone Post MAF Air Intake Hose Kit

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

57-1231-RED

Overview:

The HPS Reinforced Silicone Post MAF Air Intake Hose Kit is a high-quality replacement for the restrictive stock OEM hose found on select Scion FR-S, Subaru BRZ, and Toyota 86 models. Designed for performance enthusiasts seeking improved airflow and reduced intake temperatures, this kit replaces the factory hose with a durable, high-temperature 4-ply reinforced silicone hose. By eliminating the stock sound tube, it also streamlines the intake path for better efficiency.

This upgrade is ideal for daily drivers and spirited enthusiasts who want to enhance throttle response and gain measurable power improvements without the need for engine retuning. The hose’s reinforced construction ensures long-lasting durability under heat and pressure, making it a reliable upgrade for your vehicle’s air intake system.

Key Features:

This post-MAF hose kit offers several technical advantages that contribute to improved engine performance and reliability:

• Constructed from high-temperature 4-ply reinforced red silicone for superior heat resistance and durability.
• Replaces the restrictive OEM post-MAF hose to improve airflow and reduce intake heat soak.
• Deletes the stock sound tube, simplifying the intake path and reducing airflow turbulence.
• Dyno-proven performance gains of approximately +1.4 wheel horsepower and +1.2 ft-lbs of torque without requiring re-tuning.
• Precision fitment for 2013–2016 Scion FR-S, 2013–2016 Subaru BRZ, and 2017–2020 Toyota 86 models.
• Bright red silicone construction adds a clean, performance-oriented look to the engine bay.
• Improves throttle response and supports enhanced engine efficiency under various driving conditions.

Construction & Design:

The hose is engineered from a high-temp 4-ply reinforced silicone material that withstands elevated engine bay temperatures and resists cracking or deformation over time. This construction ensures consistent airflow and durability even under demanding conditions. The reinforced layers provide structural integrity while maintaining flexibility for easy installation.

The design eliminates the factory sound tube, which can restrict airflow and trap heat, thereby reducing intake efficiency. By streamlining the post-MAF section of the intake, the hose helps lower intake air temperatures and improves overall engine breathing.

Performance & Sound

• Delivers a dyno-verified increase of +1.4 wheel horsepower and +1.2 ft-lbs of torque without any ECU tuning.
• Reduces heat soak in the intake tract, helping maintain cooler, denser air for improved combustion.
• Enhances throttle response and can contribute to a more aggressive intake sound by removing the restrictive sound tube.

Installation & Fitment:

This hose kit is designed as a direct replacement for the factory post-MAF hose on compatible vehicles. It installs using existing mounting points and clamps, requiring no cutting, drilling, or special tuning. The kit fits the following vehicles precisely:

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

Installation is straightforward and can be completed with basic hand tools, making it accessible for both professional installers and knowledgeable enthusiasts.

What's Included:

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

Ideal For:
