HKS DryCarbon Full Cold Air Intake Kit - 2020+ A90 Supra

Dry Carbon Full Cold Air Intake Kit for the 2020+ GR Supra

The HKS Dry Carbon Full Cold Air Intake Kit for the 2020+ Toyota GR Supra is HKS's top-tier intake solution for the A90 platform, combining a dry carbon fiber airbox with an extended cold air intake pipe that routes the air filter away from underhood heat sources. Dry carbon construction keeps the airbox lightweight and thermally stable. Carbon fiber is a poor conductor of heat, which means the airbox itself does not absorb engine bay heat the way aluminum or plastic does. Cooler intake temperatures mean denser charge air and more consistent power.

Specs & Highlights

• Dry carbon fiber airbox construction
• Cold air routing away from heat sources
• Maximizes intake charge density
• Significant airflow improvement over OEM and short ram setups
• Compatible with HKS SSQV4 and other BOV kits
• Fitment: 2020+ Toyota GR Supra (A90)

Pre-Preg Construction and Temperature Reduction

The dry carbon airbox is manufactured using pre-preg carbon fiber layup at 2×2 twill weave, vacuum-bagged and autoclave cured for consistent fiber density. The intake pipe is 80mm (3.15 inch) inner diameter aluminum, matching the factory MAF housing diameter for direct sensor compatibility. HKS claims an intake air temperature reduction of 10–18°C versus the stock airbox under sustained driving conditions, translating to roughly 1–2% air density improvement and corresponding power consistency improvement on a tuned B58.

The Thermal Case for Dry Carbon

The full cold air kit goes further than the HKS Super Air Filter or the standard cold air box by routing the intake pickup to a cooler location in the engine bay. The B58 makes meaningful power from intake air temperature improvements. Every 10 degrees Celsius of intake charge temperature reduction translates to approximately 1% in air density improvement, and the compounding effect of cooler, denser air through a less restrictive path adds up quickly on a turbocharged application.

Installation Scope and MAF Compatibility

Dry carbon construction also means the intake system is significantly lighter than the factory plastic and rubber assembly. For a car as weight-conscious as the GR Supra, reducing mass in the engine bay is a worthwhile secondary benefit. Installation requires some disassembly of the factory intake system but follows documented procedures with the included instructions.

The FT Breakdown

The dry carbon full cold air kit is the intake system for serious A90 Supra builds. If you are already running the HKS exhaust and coilovers, the intake is the third major piece of the bolt-on performance foundation. The dry carbon construction is consistent with the rest of the HKS carbon lineup for the Supra and the engineering reflects HKS's motorsport background rather than their catalog business. The 10–18°C intake temperature reduction documented by HKS is significant on a forced induction platform where charge air density directly affects power consistency. A car that loses 8% of its power on the third run on a hot track day and a car that loses 3% are very different track tools.
