What does the AMS Performance Toyota GR Supra intake manifold do that the factory unit cannot?

The AMS Performance Toyota GR Supra intake manifold integrates a parallel twin-core air-to-water intercooler directly into the manifold, actively cooling intake charge air as power levels rise — something the factory B58 manifold does not do. It also adds properly angled port fuel injection positions on the runners for secondary port injection alongside direct injection, enabling ethanol flex fuel and higher peak horsepower without relying on injector spacers.

How does the parallel split core design benefit the AMS Performance Toyota GR Supra intake manifold?

The parallel split core routes coolant from the centre of the unit rather than end-to-end, reducing water pressure drop and pairing the coolest coolant with the coolest air at the furthest point through the intercooler cores. This maximises heat transfer across the entire length of the cores, ensuring consistent cooling of each cylinder rather than progressively warmer air toward the ends.

Does the AMS Performance Toyota GR Supra intake manifold require any modifications to install?

No. The AMS Performance Toyota GR Supra intake manifold is a direct bolt-in installation with no modifications required to the vehicle. It is fully compatible with the factory AC system, power steering, oil filter cap, and all other OEM options, and is fully reversible.

Which injectors are compatible with the AMS Performance Toyota GR Supra intake manifold fuel rail?

The fuel rail is designed for Bosch injectors, with the Injector Dynamics 1050.34.14.14.6 as the confirmed fitment. Other Bosch injectors may be compatible with 14mm bore lower and upper o-rings and no top cap. Injectors are not included and must be sourced separately.

What power level does the AMS Performance Toyota GR Supra intake manifold support?

The AMS Performance Toyota GR Supra intake manifold is rated to 1,250+ horsepower through the parallel twin-core air-to-water intercooler system. The 135% larger core area over OEM and 1-inch ID coolant hoses ensure adequate heat transfer capacity for builds targeting these power levels.

Description

AMS Performance Intake Manifold for A90 / A91 Toyota GR Supra

Toyota GR Supra intake manifold from AMS Performance is a direct bolt-in A356 T6 cast aluminum intake manifold with integrated parallel twin-core air-to-water intercooler for the A90 and A91 GR Supra (B58 3.0L I6 turbo, 2020-present), rated to 1,250+ horsepower and featuring a flush-mounted -8AN auxiliary port fuel rail for secondary port fuel injection addressing the two key limitations of the factory B58 system as power levels rise: heat soak and the inability to run port fuel injection alongside the factory direct injection. The AMS Performance Toyota GR Supra intake manifold installs without modification to the vehicle and is fully reversible, compatible with the factory AC system, power steering, oil filter cap, and all other OEM options.

Why the AMS Performance Toyota GR Supra Intake Manifold?

As power levels increase in the B58-powered GR Supra, intake charge air temperatures rise with them. The factory intake manifold provides no active cooling of the charged air between the intercooler and the cylinder head. The AMS Performance Toyota GR Supra intake manifold solves this with a parallel split core design that routes coolant from the center of the unit rather than end-to-end, reducing water pressure drop, increasing flow rate at a given head pressure, and pairing the coolest coolant with the coolest air at the furthest point through the intercooler for maximum heat transfer across the entire length of the cores. The 135% larger core area over the OEM unit and 1-inch ID coolant hoses (148% larger than OEM) ensure the system can move heat fast enough to support builds targeting 1,250+ horsepower. The coolant port design also supports integration of a custom ice tank for time-attack or drag strip applications. On the fueling side, the factory B58 direct injection system limits ethanol flex fuel use and peak horsepower. The AMS manifold incorporates properly angled port injector positions on the runners, angled directly at the intake valve and combustion chamber to eliminate fuel pooling. The flush-mounted -8AN fuel rail and pocketed runner design give the injectors the most direct spray path possible for maximum fuel atomization and combustion efficiency. The AMS Performance Toyota GR Supra intake manifold is CFD-verified with airflow distribution to within 0.5% deviation across all six cylinder ports.

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.
