AMS Performance Heat Exchanger for A90 Toyota GR Supra

With an impressive track record of two decades dedicated to research and development in the realm of forced induction, AMS Performance has solidified its position as a powerhouse within the automotive aftermarket industry. Their unmatched performance systems serve as the benchmark by which all others are measured. Embrace the role of the Alpha.

Whether you reside in a hot climate region, indulge in drag racing, or relish in high-speed runs on airstrips, the AMS Performance Toyota GR Supra Heat Exchanger is designed to ensure your intake temperatures remain lower, allowing your GR Supra to sustain its maximum power output regardless of the conditions. Unlike the traditional air-to-air front mount intercoolers (FMICs) you may be accustomed to, your 3.0L turbocharged B58 engine utilizes a coolant-based system to cool the intake air charge through an air-to-water heat exchanger. While this approach may suffice for a stock vehicle under ideal circumstances, it becomes susceptible to heat soak, resulting in a loss of horsepower.

Engineered To Win

  • With the goal of creating the ultimate heat exchanger upgrade for the AMS Performance Toyota GR Supra, the dedicated SnailWorks© Engineering Team focused not only on performance but also on ease of installation. Countless hours of research and development were invested, utilizing Solidworks© Computer Aided Design (CAD) software, coupled with extensive on-track testing. Remarkably, the heat exchanger is designed to fit seamlessly, just like the stock unit, requiring no cutting or drilling. Leveraging the existing factory hoses, clamps, and mounting points, you or your trusted mechanic can effortlessly install it in no time. The core effortlessly slides into place, securely locking into the factory mounts, and can be easily connected to your pre-existing factory coolant lines. This streamlined installation process ensures a clean and straightforward experience, leaving you with a sense of satisfaction and confidence in your upgraded setup.
  • Maximizing thermal transfer efficiency relies on expanding the overall surface area of the heat exchanger. AMS Performance understands this principle, which is why they have incorporated a substantial 54% increase in core volume compared to the small OEM unit. This significant enhancement reduces the time required for heat extraction from the system, optimizing cooling performance. Furthermore, AMS has strategically augmented the fluid volume of the entire system by nearly half a gallon, effectively transforming the heat exchanger into a generous fluid reserve. This expanded fluid capacity serves to enhance thermal capacity, ensuring coolant temperatures remain consistently low and stable. With a remarkable 122% increase in coolant capacity compared to the stock setup, the AMS heat exchanger significantly bolsters thermal stability within your Supra’s intercooler system, successfully fending off the detrimental effects of horsepower-reducing heat soak.

The Difference Is In The Details

  • The heat exchanger core serves as the pivotal component in an air-to-water intercooler system. Compromising on its quality could potentially result in a “upgraded” system performing worse than the stock setup. Recognizing its paramount importance, AMS Performance has developed a high-efficiency, dual-pass core for their Toyota GR Supra Heat Exchanger. This intelligently designed core enables the coolant to traverse the heat exchanger twice, effectively dissipating heat at an accelerated rate for optimal cooling performance. The AMS Performance team meticulously evaluated numerous core types, considering various sizes and features, to ensure the highest level of performance. Ultimately, they selected a 5mm tall louvered fin design for the Toyota GR Supra Heat Exchanger. This choice proved to deliver the best heat transfer capabilities and boasted the optimal coolant tube count among all the fin designs tested. Furthermore, the louvered fin design provides additional surface area, facilitating more efficient heat transfer out of the core.
  • The significance of component design and material selection cannot be overstated when it comes to product development, which is precisely why AMS Performance has employed top-tier materials as the cornerstone of their Toyota GR Supra Heat Exchanger. The end tanks of this heat exchanger are expertly crafted from billet 6061 T6 aluminum, ensuring exceptional quality. To achieve a flawless fit, these tanks undergo precision CNC machining, guaranteeing a perfect fit every time. Leveraging the use of billet end tanks, AMS Performance has ingeniously incorporated OEM-style fitment features into the design. As a result, the heat exchanger seamlessly locks into place, precisely as intended by Toyota. These unique features are seamlessly integrated into the billet end tanks, setting our kit apart from the competition and making it difficult to replicate.

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.
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.
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 with any inquiries.
