HKS Cold Air Intake Full Kit - 2020-2021 Toyota A90 Supra

Cold Air Intake Full Kit for the 2020-2026 GR Supra

The HKS Cold Air Intake Full Kit for the 2020-2021 Toyota GR Supra replaces the factory intake path with an aluminum pipe and HKS performance filter, routing the intake pickup to a cooler location in the engine bay. The kit improves both airflow volume and intake charge temperature over the factory setup. Two variables that directly affect the density of air entering the B58's compressor. Cooler, denser air makes more power and allows more aggressive boost without detonation risk.

• Aluminum intake pipe construction
• HKS performance filter included
• Cold air routing for improved charge temperature
• Compatible with factory BOV or HKS SSQV4 upgrade
• Fitment: 2020-2026 Toyota GR Supra

80mm Pipe Diameter and Temperature Improvement

The AT002 aluminum intake pipe is 80mm inner diameter, matching the factory MAF housing bore for direct sensor compatibility without an adapter. The cold air routing positions the filter pickup approximately 250mm lower in the engine bay than the factory airbox, away from the primary heat sources. Under sustained operation, documented intake air temperature reduction versus the stock setup is approximately 10–18°C. The system also reduces the factory intake resonance noise that some A90 Supra owners find intrusive at partial throttle, replacing it with a cleaner induction note.

Why Intake Air Temperature Matters on the B58

The 2020-2021 B58 Supra responds well to intake work. The factory airbox is positioned close to several heat sources and the OEM intake tract makes a number of compromises for space and noise. The HKS cold air kit addresses both by using an aluminum pipe for thermal stability and relocating the filter pickup to a cooler region of the engine bay. The improvement in charge air temperature is more significant than the flow improvement alone.

2020-2021 Specific Fitment, Dry Carbon Also Available

This is the 2020-2021 specific kit. A separate dry carbon version is available for those prioritizing weight and thermal performance at a higher price point. Installation requires removing the factory airbox assembly and follows the included installation guide. No permanent modification to the factory system is required.

The FT Breakdown

The cold air intake is one of the highest-return bolt-on modifications for the A90 Supra. Combined with the HKS Super Turbo Muffler and the HIPERMAX S coilovers, it forms the core of the bolt-on performance foundation HKS recommends for this platform. For GR Surpa owners, this is the intake kit to get. The 80mm pipe diameter matched to the factory MAF bore means no adapter, no air leak risk, and no flow transition at the sensor — the intake tube passes cleanly through the measurement point. That detail matters on a precision fuel injection system where small leaks downstream of the MAF cause trims the ECU cannot fully correct.
