Overview:

The HPS Reinforced Silicone Post MAF Air Intake Hose and Sound Tube 2-piece kit is a direct replacement for the factory post-MAF hose and sound tube on select Subaru BRZ, Toyota 86, and Scion FR-S models. Designed for enthusiasts seeking improved airflow and reduced intake heat soak, this high-temperature, 4-ply reinforced silicone hose enhances your vehicle’s intake efficiency without requiring any tuning adjustments.

By upgrading from the restrictive OEM rubber hose to durable silicone, you’ll experience smoother airflow and better throttle response. This kit also replaces the stock sound tube with a silicone version, maintaining proper engine sound management while improving durability and heat resistance.

Key Features:

This kit offers several benefits that enhance both performance and reliability:

• Constructed from high-temperature 4-ply reinforced black silicone for superior durability and heat resistance compared to OEM rubber hoses.
• Improves airflow post-MAF sensor, reducing intake restriction and heat soak for more consistent engine performance.
• Dyno-proven performance gains of approximately +1.4 wheel horsepower and +1.2 ft-lbs of torque without requiring ECU retuning.
• Includes a silicone sound tube replacement that maintains factory sound management while offering improved longevity.
• Direct bolt-on replacement using factory mounting points for a hassle-free installation.
• Resistant to cracking, collapsing, and deformation under high heat and pressure conditions.
• Compatible with Subaru BRZ (2013–2016), Toyota 86 (2017–2020), and Scion FR-S (2013–2016) models.

Construction & Design:

The post-MAF hose and sound tube are crafted from premium high-temp silicone reinforced with four layers of durable fabric. This multi-ply construction ensures excellent resistance to heat, pressure, and environmental wear, outperforming the stock rubber components. The silicone material also helps reduce heat soak, keeping intake air temperatures lower for improved combustion efficiency.

The kit’s design maintains the OEM shape and fitment, ensuring seamless integration with the factory intake system and MAF sensor. The silicone sound tube replacement preserves the original sound tuning characteristics while offering enhanced durability and flexibility.

Performance & Sound

• Delivers measurable gains of +1.4 wheel horsepower and +1.2 ft-lbs torque as verified on a dynamometer.
• Improves throttle response by reducing airflow restrictions after the MAF sensor.
• Helps reduce intake air temperatures by minimizing heat soak, contributing to more consistent engine performance.
• Maintains factory intake sound characteristics with the included silicone sound tube replacement.

Installation & Fitment:

This HPS kit is designed for a straightforward, bolt-on installation using existing factory mounting points and hardware. No cutting, drilling, or special tuning is required, making it an ideal upgrade for enthusiasts who want improved performance without complicated modifications.

• Fits Subaru BRZ models from 2013 to 2016.
• Also compatible with Toyota 86 (2017–2020) and Scion FR-S (2013–2016).
• Replaces the factory post-MAF hose and sound tube directly.

What’s Included

• One high-temperature 4-ply reinforced black silicone post-MAF air intake hose.
• One silicone sound tube replacement.
