Mishimoto Silicone Induction Hose
2022–2024 Subaru BRZ / Toyota GR86 FA24D
MMHOSE-BRZ-22IHRD
Overview:
The Mishimoto Silicone Induction Hose is a direct upgrade for the naturally aspirated FA24D engine found in the 2022 and newer Subaru BRZ and Toyota GR86 models. Designed to replace the restrictive stock rubber induction hose, this high-quality silicone hose improves airflow and durability, enhancing throttle response and overall engine performance. Ideal for enthusiasts who want to maximize the potential of their FA24 engine without forced induction, this hose ensures smoother air delivery while maintaining the factory intake tuning and powerband characteristics.
By eliminating the corrugated section of the stock hose, Mishimoto’s induction hose reduces turbulence and airflow restriction, allowing the engine to breathe more efficiently. It’s a reliable, long-lasting solution that prevents vacuum leaks and check-engine lights caused by aging rubber components, making it perfect for daily drivers and track enthusiasts alike.
Key Features:
Engineered to optimize airflow and durability, the Mishimoto Silicone Induction Hose offers several key benefits:
- 3-inch inner diameter with smooth bends to reduce airflow restriction and turbulence
- 5-ply silicone construction resists cracking, brittleness, and heat degradation
- Stainless-steel wire reinforcement prevents hose collapse at high RPM or under increased airflow demands
- Maintains the factory lower resonator to preserve Subaru’s intake tuning and powerband
- Direct bolt-on replacement for the stock induction hose with no modifications required
- Compatible with stock engine tune and supports future performance upgrades such as cams and ECU tunes
- Includes all necessary hardware for a straightforward installation
- Backed by Mishimoto’s Lifetime Warranty for peace of mind
Construction & Design:
The Mishimoto induction hose is crafted from premium 5-ply silicone, chosen for its superior flexibility, heat resistance, and longevity compared to OEM rubber hoses. The smooth internal surface eliminates the corrugations found in the stock hose, which are a common source of airflow turbulence and power loss. Reinforced with a stainless-steel wire helix, the hose maintains its shape and resists collapsing under vacuum or high airflow conditions, ensuring consistent performance even at elevated RPMs or when paired with aftermarket modifications.
Its precision-engineered shape matches the factory airbox and throttle body connections with a consistent 3-inch diameter, ensuring seamless airflow and preventing pressure drops. The design also retains the factory lower resonator chamber, preserving the intake sound characteristics and tuning that contribute to the FA24D’s unique driving experience.
Performance & Sound
By replacing the restrictive stock rubber hose with a smooth silicone alternative, this induction hose improves throttle response and volumetric efficiency. The reduction in airflow turbulence allows the engine to inhale air more freely, which can translate into a more responsive and lively driving experience. Additionally, maintaining the factory resonator ensures that the signature intake sound remains intact, providing an engaging auditory feedback without unwanted drone or harshness.
Installation & Fitment:
The Mishimoto Silicone Induction Hose is designed for a direct, bolt-on installation on 2022 to 2024 Subaru BRZ and Toyota GR86 models equipped with the FA24D engine. Installation typically takes under an hour and requires no special tools or modifications. The hose comes with all necessary clamps and hardware, making it a straightforward upgrade for enthusiasts looking to enhance their vehicle’s intake system reliability and performance.
What's Included:
- 1 x Mishimoto Silicone Induction Hose (3-inch inner diameter)
- Stainless-steel clamps for secure fitment
- Installation instructions
Ideal For:
This induction hose is perfect for Subaru BRZ and Toyota GR86 owners who want to improve their naturally aspirated FA24D engine’s airflow and reliability. It suits daily drivers seeking a durable OEM replacement as well as performance enthusiasts preparing their cars for future upgrades such as camshafts, ECU tuning, or track use. The hose is also ideal for anyone looking to prevent vacuum leaks, check-engine lights, and power loss caused by aging stock rubber components.
