What does the AMS Performance Toyota GR Supra heat exchanger do that the stock unit cannot?

The AMS Performance Toyota GR Supra heat exchanger has 54% more core volume and 122% more coolant capacity than the small OEM unit, with a dual-pass core that routes coolant through twice for faster heat dissipation. This combats the heat soak the B58's air-to-water intercooler system is prone to under demanding conditions, keeping intake temperatures and power output stable in hot climates, on the drag strip, and during high-speed runs.

Is the AMS Performance Toyota GR Supra heat exchanger a direct fit?

Yes. The AMS Performance Toyota GR Supra heat exchanger fits exactly like the stock unit with no cutting or drilling. It uses the existing factory hoses, clamps, and mounting points — the core slides in, locks into the factory mounts via OEM-style fitment features, and connects to the pre-existing factory coolant lines.

What is a dual-pass core and why does it matter on the AMS Performance Toyota GR Supra heat exchanger?

A dual-pass core routes the coolant through the heat exchanger twice rather than once, dissipating heat at an accelerated rate for better cooling performance. On the AMS Performance Toyota GR Supra heat exchanger, this is paired with a 5mm tall louvered fin design selected for the best heat transfer and coolant tube count of all designs AMS tested.

How does the extra coolant capacity of the AMS Performance Toyota GR Supra heat exchanger help?

The AMS Performance Toyota GR Supra heat exchanger adds nearly half a gallon of fluid to the system — a 122% increase in coolant capacity — effectively acting as a fluid reserve. This larger thermal mass keeps coolant temperatures lower and more stable, improving thermal stability throughout the intercooler system and resisting horsepower-reducing heat soak.

Are the end tanks on the AMS Performance Toyota GR Supra heat exchanger plastic like the OEM unit?

No. The end tanks on the AMS Performance Toyota GR Supra heat exchanger are CNC-machined from billet 6061 T6 aluminum, with OEM-style fitment features integrated directly into the tanks. This ensures a precise factory-style fit and greater durability than the stock design.

Description

AMS Performance Heat Exchanger for A90 / A91 Toyota GR Supra

Toyota GR Supra heat exchanger from AMS Performance is a direct-fit dual-pass heat exchanger upgrade for the A90 and A91 GR Supra (B58 3.0L I6 turbo, 2020-present), engineered to keep intake charge temperatures low and preserve peak power in hot climates, on the drag strip, and during extended high-speed runs. The GR Supra’s B58 engine uses an air-to-water intercooler system rather than a traditional air-to-air front mount, which makes it prone to heat soak under demanding conditions the AMS Toyota GR Supra heat exchanger addresses this directly with a 54% larger core volume, a 122% increase in coolant capacity, and a high-efficiency dual-pass core, developed by AMS’s SnailWorks Engineering Team using Solidworks CAD and validated through extensive on-track testing.

Why the AMS Performance Toyota GR Supra Heat Exchanger?

In an air-to-water intercooler system, the heat exchanger is the pivotal component; a poorly designed unit can leave an “upgraded” system performing worse than stock. The AMS Toyota GR Supra heat exchanger uses a high-efficiency dual-pass core that routes coolant through the exchanger twice for accelerated heat dissipation. AMS evaluated numerous core types before selecting a 5mm tall louvered fin design that delivered the best heat transfer and the optimal coolant tube count of all designs tested, with the louvered fins adding surface area for more efficient heat extraction. The core volume is 54% larger than the small OEM unit, reducing the time needed to pull heat from the system. The expanded design adds nearly half a gallon of fluid to the system, a 122% increase in coolant capacity over stock, turning the heat exchanger into a fluid reserve that boosts thermal capacity and keeps coolant temperatures low and stable. The end tanks are CNC-machined from billet 6061 T6 aluminum with OEM-style fitment features integrated directly into the tanks. Hence, the unit locks into the factory mounts exactly as Toyota intended.

Toyota GR Supra Heat Exchanger: Direct-Fit Installation

The AMS Toyota GR Supra heat exchanger is engineered to fit exactly like the stock unit, with no cutting or drilling required. It uses the existing factory hoses, clamps, and mounting points; the core slides into place, locks into the factory mounts, and connects to the pre-existing factory coolant lines. This plug-and-play installation can be completed by an owner or a trusted mechanic in a short time using the included instructions.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
