- Mugen has announced its full catalogue of parts for the new Honda Prelude.

- It is limited to 16 units and will be offered for sale through a lottery system.
Mugen is wasting no time reminding enthusiasts that its take on the new Honda Prelude isn’t just a styling exercise. Following a teaser back in September 2025, the full catalogue of upgrades from the Japanese tuner is now available. At the top of the list is the ultra-rare “Spec.III” package, complete with retro graphics and a production run limited to just 16 cars.

The Spec.III serves as a modern homage to the Spec.II kit from 1987, designed for the third-generation Prelude, the last one with pop-up headlights. The new version includes the full carbon fiber “Group A” aero kit and a sports exhaust, though the upgraded dampers, brake pads, and BBS wheels are still sold separately.
What Makes Spec.III Special?
To give the Spec.III its own identity, Mugen adds exclusive decals and a serialized badge. The graphics run along the doors and rear quarter panels, following the rising beltline of the Prelude. In red, gold, and black over a grey base, the stickers bring a vintage feel to the otherwise modern hybrid coupe. Still, most of the visual differences between this and the standard kit are fairly restrained.
For collectors and fans alike, the main draw is likely the numbered plaque, finished in the same motorsport colors and featuring the “Mugen Prelude Spec.III” script.
The Spec.III kit is priced at ¥1,650,000 ($10,510), but money alone won’t guarantee you an order. Due to the limited production, Mugen is running a lottery system. Applications are open from January 8 to February 27, 2026, with the 16 winners to be announced on March 19. Shipping for these exclusive units is scheduled to begin on June 19.
Parts for the Rest of Us
If you’re not chasing limited-edition bragging rights, the individual “Group A” parts are readily available and can be ordered separately.

Components that anyone can buy off the shelf include the two-piece front splitter for ¥242,000 ($1,540), side skirts for ¥330,000 ($2,100), and carbon fiber mirror covers for ¥110,000 ($700). Completing the exterior transformation are the rear bumper extensions for ¥253,000 ($1,610), the rear diffuser for ¥209,000 ($1,330), and the tailgate spoiler for ¥220,000 ($1,400).
For the interior, Mugen offers branded floor mats for ¥46,200 ($295), a matching luggage mat for ¥30,800 ($195), and scuff plates for ¥29,700 ($190), all tailored to the new Prelude.
Performance Parts
For those interested in more than looks, Mugen also supplies performance hardware. The stainless steel sports exhaust is priced at ¥341,000 ($2,170). A set of 19-inch forged BBS wheels will set you back ¥704,000 ($4,485). Suspension upgrades include Yamaha-tuned dampers at ¥143,000 ($910) and high-performance brake pads for ¥52,800 ($335).

Finally, Mugen offers a range of smaller accessories such as brake and clutch reservoir covers, various stickers, oil filler caps, wheel nuts and center caps, key cases, as well as a blue hydrophobic film for the external mirrors.
How Much for Everything?
If you tick every single box on the Mugen catalogue, you’ll be charged a total of ¥2,721,240 ($17,300) before labor costs. That’s on top of the price of a new Prelude, which starts from ¥6,179,800 yen ($39,400) in Japan, making it more expensive than the Nissan Z and Toyota GR Supra despite the underwhelming Civic-sourced four-cylinder hybrid powertrain. In the US, the Japanese coupe is priced from $42,000 plus a $1,195 destination fee.
