NSX-R Style Maintenance Lid
Unibody Aluminum Construction
Engineered from a single piece of 6061 Aluminum with a welded protective mesh. Unlike fiberglass alternatives that warp or bend under engine heat, our lid remains structurally rigid and aesthetically perfect.
The MITA Maintenance Lid provides the iconic NSX-R visible engine bay aesthetic while offering superior protection against debris. Designed as a premium alternative to backordered OEM pieces, it utilizes a redesigned support frame that is 100% NSX-T (Targa) friendly—fitting the Targa firewall layout perfectly without the need for spacers.
This unit is designed for seamless integration; the original factory seal and OEM installation hardware fit this lid as intended.

Engineered For Long-Term Performance
While composite materials offer excellent weight savings, the MITA Maintenance Lid was engineered around a different philosophy: maximum durability without sacrificing weight.
Constructed from a precision-formed 6061 aluminum unibody design, the MITA Maintenance Lid provides the strength, rigidity, and long-term reliability expected from a premium NSX component. Unlike composite panels that rely on a protective clear coat to preserve their finish, the aluminum structure itself remains unaffected by UV exposure, engine heat, and everyday use.
At only 3.9 kg, the MITA Maintenance Lid achieves an exceptional lightweight design while maintaining the advantages of a metal construction:
- No carbon fiber resin aging or composite degradation over time
- No dependence on a clear coat to protect the structural material
- Superior long-term UV stability in outdoor environments
- Excellent heat resistance in the NSX engine compartment
- Repairable and refinishable using conventional aluminum restoration methods
The result is a maintenance lid designed not only to look exceptional when new, but to remain structurally sound and visually impressive for decades of NSX ownership.
Construction Comparison
| Feature | MITA 6061 Aluminum | Dry Carbon Fiber | Fiberglass |
|---|---|---|---|
| Structural Rigidity | ★★★★★ Unibody aluminum construction maintains shape under load |
★★★★☆ High stiffness-to-weight ratio |
★★★☆☆ More flexible composite structure |
| Open Position Stability | ★★★★★ Maintains alignment when supported by hinges and strut |
★★★★☆ Requires proper reinforcement and layup design |
★★★☆☆ May exhibit flex or sag under uneven loading |
| Resistance to Heat Cycling | ★★★★★ Excellent stability in engine bay temperatures |
★★★★☆ Excellent when manufactured correctly |
★★★☆☆ More susceptible to long-term shape changes |
| UV Aging | ★★★★★ Metal structure unaffected by UV exposure |
★★★★☆ Depends on clear coat protection |
★★★☆☆ Requires strong UV protection to prevent fading and surface degradation |
| Long-Term Shape Retention | ★★★★★ Maintains original geometry over time |
★★★★☆ Stable with quality composite construction |
★★★☆☆ Can be more prone to flexing and deformation |
| Repairability | ★★★★★ Straightforward aluminum repair and refinishing |
★★★☆☆ Requires specialized composite repair |
★★★★☆ Can be repaired, but structural consistency varies |
Unlike lightweight composite alternatives that rely on laminate thickness and reinforcement strategies to achieve stiffness, the MITA Maintenance Lid uses a rigid 6061 aluminum unibody structure to maintain its shape and alignment throughout years of use. This provides a consistent fit, proper hinge alignment, and confidence every time the lid is opened.
Installation Requirement:
Please ensure hinges are installed onto the maintenance lid first, then mount the assembly onto the body of the NSX.

4 reviews for MITA Aluminum NSX-R Style Maintenance Engine Lid
In search of a factory engine lid, I discovered it had been discontinued, prompting me to seek alternatives. Although the fiberglass options from Scienceofspeed were suggested, I was intent on finding something that matched OEM quality. Fortunately, I found just the thing, and it fits seamlessly with the OEM hardware functioning flawlessly. The craftsmanship is truly impressive.
Very high quality! Perfect for Targas
High quality OEM reproduction.
Fit my targa perfectly. Great
