Toyota GR Supra (A90/A91) Aluminum Closed-Box Cold Air Intake System with Turbo Inlet | B58 3.0L Turbo Engine

Maximize the performance of your A90 / A91 Toyota GR Supra with our Full Aluminum Closed-Box Cold Air Intake System, engineered for the B58 3.0L turbocharged inline-six.

This intake is crafted from lightweight, high-strength aluminum and designed as a completely sealed system to isolate your filter from engine bay heat. The top cover is reinforced with a rubber sealing strip around the lip, ensuring it sits flush against the engine wall without scratching while creating a tight seal that keeps hot air out.

Unlike traditional closed systems that suffocate airflow, this intake incorporates strategically placed slivers and inlets to introduce controlled amounts of fresh air. This balance maintains a secure closed-box design while still supplying your turbos with the excess airflow they demand under load. The result: cooler, denser, and more consistent intake temps for repeatable power and efficiency.

Performance benefits you’ll notice immediately:

1. Sharper throttle response with reduced turbo lag
2. Improved turbo spool for a smoother, more responsive drive
3. Stronger midrange torque and reliable top-end pull
4. Horsepower gains that compound with tuning

On the road, this system keeps intake temperatures under control during both spirited driving and stop-and-go heat soak conditions. It’s built to deliver OEM-level fitment with a stealthy look, while adding the audible character enthusiasts love — a refined induction tone with crisp turbo spool and controlled blow-off acoustics.
