Mishimoto Silicone Induction Hose

2022–2024 Subaru BRZ / Toyota GR86 FA24D

MMHOSE-BRZ-22IHBK

Overview:

The Mishimoto Silicone Induction Hose is a direct replacement for the stock rubber induction hose found on the 2022 and newer Subaru BRZ and Toyota GR86 equipped with the naturally aspirated FA24D 2.4-liter engine. Designed for enthusiasts who want to enhance throttle response and airflow without forced induction, this hose addresses common issues such as airflow restriction and premature wear associated with the factory corrugated rubber hose. By upgrading to a smooth, reinforced silicone hose, drivers can enjoy improved engine breathing, increased reliability, and a more consistent power delivery on both street and track.

This product is ideal for owners looking to maintain the naturally aspirated character of their FA24D engine while optimizing intake efficiency and preparing their vehicle for future performance modifications such as camshafts or ECU tuning.

Key Features:

The Mishimoto Silicone Induction Hose offers a range of benefits that improve both durability and performance:

• 3-inch inner diameter with smooth bends to reduce airflow restriction and turbulence
• Stainless-steel wire reinforcement to prevent hose collapse at high RPM or increased airflow demands
• 5-ply silicone construction resists cracking, brittleness, and heat degradation common in rubber hoses
• Maintains the factory lower resonator to preserve Subaru’s engineered intake tuning and powerband characteristics
• Direct-fit design for a seamless transition from airbox to throttle body without modifications
• Compatible with the stock ECU tune, requiring no adjustments for immediate installation
• Backed by Mishimoto’s Lifetime Warranty for long-term peace of mind

Construction & Design:

Crafted from high-quality 5-ply silicone, this induction hose is engineered to withstand the harsh conditions of the engine bay, including heat, vibration, and chemical exposure. The smooth inner surface eliminates the corrugations found in the stock rubber hose, which are known to cause airflow turbulence and reduce volumetric efficiency. Reinforced with a stainless-steel wire helix, the hose maintains structural integrity under vacuum and high airflow scenarios, preventing collapse during aggressive driving or when paired with performance upgrades.

The hose’s design also thoughtfully retains the factory lower resonator, ensuring that the intake sound and power delivery characteristics developed by Subaru remain intact. This balance of performance and refinement makes it a superior upgrade for naturally aspirated FA24D engines.

Performance & Sound

By replacing the restrictive corrugated rubber hose with a smooth silicone alternative, the Mishimoto induction hose improves airflow into the engine, which can enhance throttle response and potentially unlock additional power potential. The reduction in intake turbulence helps the engine breathe more efficiently, especially at higher RPMs or when combined with supporting modifications such as cams or ECU tunes. Additionally, the retention of the factory resonator preserves the refined intake sound and powerband tuning unique to the BRZ and GR86.

Installation & Fitment:

Installation is straightforward and can be completed in under an hour using common hand tools. The hose is a direct bolt-on replacement for the stock induction hose on 2022–2024 Subaru BRZ and Toyota GR86 models equipped with the FA24D engine. No cutting, trimming, or additional modifications are required, making it an accessible upgrade for enthusiasts of all skill levels. The package includes all necessary clamps and hardware for a secure fitment.

What's Included:

• Mishimoto 3-inch silicone induction hose with stainless-steel wire reinforcement
• All required clamps and mounting hardware for installation
• Detailed installation instructions

Ideal For:

This induction hose is perfect for Subaru BRZ and Toyota GR86 owners who want to improve intake airflow and durability without sacrificing the naturally aspirated engine’s character. It is especially beneficial for those planning future performance upgrades such as camshafts, ECU tuning, or other modifications that increase airflow demand. Additionally, it suits drivers seeking a reliable, long-lasting replacement for the factory rubber hose prone to cracking and vacuum leaks over time.
