Owners of the legendary 1991-2005 Acura NSX have long faced a dwindling supply of original components, often resorting to salvage yards or aftermarket improvisations. In response, Honda has opened a dedicated channel that aims to keep as many authentic NSXs as possible cruising U.S. streets. The initiative, known as the Honda Heritage Parts program, debuted in Japan in April and reached American customers on November 2, when Acura dealerships and the Honda DreamShop began offering more than 3,000 reproduction items. By reproducing components with the same materials and manufacturing techniques used in the original production run, the program promises a factory-level restoration experience without the wait for rare donor cars.
Heritage Parts program reaches U.S. NSX owners
From Japan to American showrooms
The Heritage Parts effort started as a domestic Japanese service, aimed at preserving JDM first-generation NSXs through a full-scale restoration offering. After refining the catalog and production processes, Honda expanded the program overseas earlier this year, selecting the iconic NSX as the inaugural model for the U.S. rollout. American enthusiasts can now order parts directly from any Acura dealer nationwide or via the online Honda DreamShop. This dual-channel approach mirrors Honda’s strategy of making classic-performance support as accessible as a new-car purchase, ensuring that even out-of-state owners can obtain the exact pieces they need without lengthy cross-border shipping delays.
What’s in the catalog: genuine reproductions and compatible replacements
Engine, transmission and chassis essentials
The catalog is split into two distinct families. Genuine Honda Reproduction Parts are forged using the original dies, alloys, and tolerances, essentially providing a like-for-like swap that satisfies purists seeking numbers-matching authenticity. In contrast, Honda Compatible Parts are newly engineered solutions designed to replace items that Honda no longer manufactures; they fit correctly and perform to spec, though they may not mirror the historic production process. For a 1994 NSX equipped with a four-speed automatic, the offering includes fuel injectors, throttle bodies, exhaust manifolds, oil coolers, alternators, camshafts, timing belts and virtually any engine-side hardware a restorer could imagine.
Transmission components receive equally comprehensive coverage. Both automatic and manual gearboxes are supported with new cases, gear shafts, shift forks, shift levers, and a full suite of bolts. Exterior and under-body items such as exhaust systems, radiators, headlights, taillights, and wiring harnesses are also reproduced. Interior accessories—from gauge clusters to trim panels, windshield replacements, and even genuine spark plugs or oil filters—can be ordered online or through an Acura service desk. Wheel, brake, and shock-absorber assemblies round out the lineup, giving owners a one-stop source for a complete, factory-grade overhaul.
How to obtain the parts and why it matters
Purchasing is straightforward: customers contact their local Acura dealership, which can pull the specific part number from the online database, or they browse the DreamShop portal for direct ordering. Pricing details are not published en masse; instead, each component’s cost is disclosed during the quote process, reflecting the labor-intensive nature of exact-spec reproduction. Executive Vice President Mamadou Diallo of American Honda Motor emphasized the program’s purpose, stating, “Honda Heritage Parts was created to help our customers enjoy their classic Acura and Honda performance models, and it’s appropriate that we begin with an iconic model like the first-generation Acura NSX. By supporting our customers in preserving the legacy of the NSX, we’re celebrating our shared passion for these iconic sports cars and keeping them on the road for today’s enthusiasts and future generations.”
Beyond parts, Honda launched a parallel Honda Restoration Service in Japan, offering full-vehicle refurbishments using the same reproduced components. While that service currently remains exclusive to JDM owners, its existence signals a broader commitment to the model’s longevity. For U.S. collectors, the availability of genuine parts reduces reliance on scarce junkyard finds, potentially stabilizing the secondary-market value of the NSX and encouraging more owners to undertake comprehensive restorations rather than settle for partial fixes.
Acura’s broader brand context reinforces the significance of the Heritage Parts launch. In 2025, roughly 85 % of Acura’s U.S. sales were produced domestically, underscoring a corporate focus on high-quality engineering and supply-chain control. By extending that philosophy to a classic, Honda leverages its modern manufacturing expertise to service a vehicle that helped define the brand’s performance DNA. The result is a seamless bridge between past and present, allowing a new generation of drivers to experience the NSX’s legendary handling with the confidence that comes from truly original components.
The Heritage Parts initiative delivers a robust, dealer-backed solution for NSX owners who once faced a patchwork of aftermarket options. With over 3,000 parts spanning powertrain, chassis, electrical and interior systems, the program not only revives the practical maintainability of the first-generation supercar but also reinforces Honda’s commitment to preserving automotive history. Whether a collector seeks a meticulous, numbers-matching rebuild or simply needs to replace a worn-out headlight, the new supply chain promises factory-level quality, nationwide accessibility, and a clear path to keep the NSX alive on modern roads.
