MST Cold Air Intake Kit – 2022-2026 GR86 / Subaru BRZ 2.4L

MST Cold Air Intake Kit — 2022-2026 Toyota GR86 / Subaru BRZ 2.4L

V2 Enclosed Airbox Intake for the FA24-Powered GR86 and BRZ
The MST GR8602 is the V2 cold air intake for the 2022-2026 Toyota GR86 and Subaru BRZ equipped with the FA24 2.4L naturally aspirated engine. MST redesigned the airbox for the V2 with an additional intake port to significantly increase the volume of incoming cold air, paired with a wide-mouth intake duct and a 152mm high-flow filter. On the dyno, MST saw approximately 8-10 hp and 12 Nm of torque over the factory intake — meaningful gains on a naturally aspirated sports car.

Additional Intake Port — More Cold Air Volume
The key design change in the V2 airbox is the additional intake port. On a naturally aspirated engine, total airflow volume is the primary factor limiting peak output — cold air enters the intake passively rather than being forced by a turbocharger. MST’s additional port increases the opening area through which cold air can enter the airbox, addressing this limitation. The result is a larger volume of cooler, denser air reaching the throttle body, which supports more complete combustion at higher RPM.

Wide-Mouth Intake Duct
The wide-mouth intake duct creates a smooth, low-restriction path between the cold air source and the airbox. On a naturally aspirated engine where every degree of intake restriction translates directly to lost potential, the duct geometry matters — MST’s wide-mouth design minimizes the pressure drop across the intake path.

8-10 HP on an NA Platform — What That Means
An 8-10 hp gain from an intake on a naturally aspirated car is significant. Turbocharged engines can often see similar gains just from a filter upgrade, but NA motors give up nothing for free — every horsepower comes from optimizing the air path. MST’s dyno data of +8-10 hp and +12 Nm is the result of the additional intake port, wide-mouth duct, and 152mm filter working together, not just the filter change alone.

Why Choose MST Performance

MST Performance is a Taiwan-based manufacturer specializing in cold air intake systems for sport compact and performance cars. Their intakes are engineered with application-specific airbox designs that prioritize heat isolation, filter access, and direct-fit installation. MST builds their kits with enclosed airbox designs, clear top covers for easy visual inspection, and high-flow 152mm filters, giving enthusiasts a meaningful upgrade over the factory intake without requiring a tune or modification to the ECU. Every kit is designed to bolt directly onto the stock airbox mounting locations and uses the factory MAF sensor and hardware for a clean, reversible installation.

The RallySport Take

The MST GR8602 is the intake for FA24 GR86 and BRZ owners who want real performance gains, not just intake noise. The additional airbox port and wide-mouth duct design do actual work on a naturally aspirated platform — 8-10 hp is a meaningful increase for a car in this category. The clear top cover and direct-fit installation make it as easy to maintain as it is to install.
