MST Toyota Supra A90/A91 B58 Cold Air Intake + Inlet | XPH
28th Aug 2026
Unlock greater airflow and a more aggressive turbocharged character from your 2020–2025 Toyota Supra A90/A91 with the B58 3.0L engine with the MST Cold Air Intake System + Turbo Inlet Pipe (TY-SUP07).
Designed as a complete intake upgrade, the MST system replaces the restrictive factory intake components with a larger, high-flow intake assembly engineered to improve airflow to the turbocharger while helping protect the intake charge from excessive engine-bay heat. The system combines a heat-resistant HDPE airbox, a 152mm reusable high-flow filter, a 6-inch intake tube, and an enlarged-diameter turbo inlet designed to support both OEM and compatible hybrid turbo applications.
Designed for the B58 3.0L Turbo
The Toyota Supra's B58 turbocharged inline-six responds well to improvements in its intake path. The MST TY-SUP07 is engineered specifically around the A90/A91 B58 3.0L platform, providing a larger and more optimized route for air traveling toward the turbocharger.
The enlarged intake design is intended to improve airflow capacity while maintaining a direct connection to the factory vehicle. MST also incorporates an inner golf-ball surface into the intake tube, which is designed to optimize airflow characteristics through the system.
The result is a more performance-oriented intake path that can contribute to improved throttle response, enhanced engine performance, and stronger turbocharger sound.
High-Flow 152mm Filter and 6-Inch Intake Tube
At the heart of the system is a 152mm reusable high-flow air filter paired with a large 6-inch intake tube.
The increased filter and intake dimensions provide additional airflow capacity compared with the factory-style system, allowing the B58 to draw air through a less restrictive intake path.
The reusable filter is also designed for long-term use and can be cleaned periodically rather than replaced after every service interval. MST recommends cleaning the filter every 20,000 km and replacing it at 60,000 km.
HDPE Airbox Helps Control Intake Temperatures
The intake system uses an HDPE airbox designed to help protect the intake from engine-bay heat and reduce heat soaking.
Managing intake temperatures is particularly important on turbocharged engines, where hot intake air can negatively affect performance consistency. By separating the filter and intake path from the surrounding engine-bay heat, the MST airbox is designed to provide a more controlled source of intake air.
The result is an intake system designed not only for increased airflow, but also for consistent operation during demanding driving conditions.
Enlarged Turbo Inlet for OEM and Hybrid Turbos
The TY-SUP07 incorporates an enlarged-diameter turbo inlet design intended to accommodate both OEM and compatible hybrid turbocharger applications.
This additional airflow capacity makes the system suitable for enthusiasts looking beyond a completely stock configuration. However, MST specifically recommends confirming the exact turbocharger specifications before ordering when using a hybrid or aftermarket turbo.
This makes the TY-SUP07 a versatile foundation for Supra builds ranging from lightly modified street cars to more extensively upgraded B58 applications.
More Aggressive Turbo Sound
Performance upgrades do not have to be purely about numbers. The MST intake also changes the acoustic character of the Supra.
The larger intake path and revised inlet design allow more of the B58's turbocharger and induction sound to be heard under acceleration. MST specifically describes the system as providing a more aggressive turbo sound, giving the Supra a more pronounced performance character every time you get into the throttle.
Direct-Fit Installation with No ECU Remap Required
The MST TY-SUP07 is designed as a direct-fit upgrade for the factory vehicle and does not require an ECU remap or engine tune for installation.
This makes it an accessible upgrade for Supra owners who want to improve the intake system without immediately committing to ECU calibration changes. The system can also serve as part of a larger performance build where additional tuning and turbocharger upgrades are introduced later.
