Acura began selling more than 3,000 reproduction parts for the 1991-2005 first-generation NSX in the United States on November 2, moving the Honda Heritage Parts program from announcement to actual orders. The parts are available through Acura dealerships and Honda's DreamShop.
The catalog spans powertrain, chassis, electrical, exterior and interior systems, a deliberately broad scope for a car whose used-parts supply is notoriously thin. American Honda Motor Co., Inc. confirms the 3,000-plus figure applies specifically to the first-generation NSX.
Two tiers of parts, and an information gap
The catalog is split into two categories that matter to anyone restoring a car to original specification. Genuine Honda Reproduction Parts are made with the same materials and production methods as the factory originals, effectively correct replacements. Honda Compatible Parts are redeveloped substitutes for components Honda no longer manufactures, engineered to fit and function properly without necessarily following the original production process.
Neither Acura nor Honda has published a part-by-part breakdown showing which category each component falls under, and pricing does not appear in the launch materials. Buyers have to check the catalog directly or work with a dealer parts department to confirm whether a given piece, such as a wiring harness or bumper cover, is available and under which designation.
That gap has practical consequences during a restoration, since the category a part belongs to can affect both cost and how long a repair takes. Confirming availability before booking a repair timeline avoids a wasted dealer trip.
Why a supercar gets a parts program
Keeping a low-volume supercar supplied decades after production ends is the point of the program: it lets owners maintain and keep cars that would otherwise be parked because a single component is missing. Mack Hogan, writing on the launch, noted that supporting a supercar long after production can also strengthen the second-hand market and the broader value of the nameplate, which matters to anyone treating a first-gen NSX as an investment.
Acura had already detailed the Heritage Parts program months before the November 2 sales start, so the news is the switch from plan to order book rather than a surprise reveal.
What comes next is unnamed
Honda has said Heritage Parts will eventually extend to additional classic Acura and Honda performance cars, but it has not named which models will follow the NSX. Until that list appears, first-gen NSX owners are the only ones with a factory parts channel under this program.
