Infinity Design Toyota Supra (A90) B58 Carbon Intake
This product was designed to be a dramatic upgrade, with a focus on delivering the maximum amount of smooth airflow. The factory airbox is undersized and houses a small air filter. By increasing the size of the inlet tube and expanding it outward, this system creates the largest venturi tube on the market, paired with a massive air filter.
The air filter housing draws its feed from the OEM duct and includes an additional opening at the lower and front sections, allowing for the maximum volume of air to be pulled in.

Air Filtration
Housed within the beautifully shaped carbon enclosure is a bespoke, short-stack, high-surface-area filter. At a generous 170mm (6 3/4″), it is larger than any cone filter design currently on the market. The filter is designed to take full advantage of the intake tube by altering the airflow’s direction toward the outer walls.
By positioning the air filters in front of the inlet tube, the design achieves the largest velocity stack ever seen for the Supra, resulting in superior laminar flow. The choice for the largest possible air filter was deliberate. A larger filter not only allows for more airflow and power but also remains efficient at its primary purpose—filtering harmful elements from the air—for a longer period without clogging.
Air Intake Temperatures & Heat Soak
Intake temperatures are engineered to match the factory system. Additionally, the system changes airflow characteristics for a smoother delivery, allowing more air to enter the plenum.
This fully developed and intelligently designed intake system isn’t just a cosmetic upgrade. It serves as an impeccable air-smoothing device, increasing available air and air speed. The system filters air more efficiently and for longer, keeps intake air temperatures low, and creates a race-car-like intake noise under load. Most importantly, it makes the engine feel more alive, responsive, and enjoyable to use in all driving conditions.
