Why OEM Parts Matter for the G-63
Every Mercedes AMG G-63 deserves components engineered to the brand’s precise standards. OEM, or Original Equipment Manufacturer, means the part comes straight from Mercedes’ production line—engineered, tested, and guaranteed to fit as intended.
Moreover, using Mercedes AMG G-63 Air Vent Trim Panels Rear Window Black OEM A4638691400 and Mercedes AMG G-63 Spare Wheel Cover Magno Green OEM A4638690800 ensures both function and flawless aesthetics.
For example, Mercedes meticulously matches trim finishes and body panel paint formulas to your exact G-Class configuration.
Thus, authentic OEM parts deliver the perfect alignment, longevity, and finish that maintains both warranty and value.
Key OEM Parts Categories and Specifications
Let’s look at two critical parts for the G-63:
- Mercedes AMG G-63 Air Vent Trim Panels Rear Window Black OEM A4638691400
- Mercedes AMG G-63 Spare Wheel Cover Magno Green OEM A4638690800
The rear air vent trim panel serves both functional and cosmetic roles. It precisely directs airflow while blending into the rear cabin’s luxury look. Crafted using high-density polymers and finished in Mercedes’ gloss black, this OEM trim ensures durability and color match—even under years of sun exposure.
Meanwhile, the Magno Green spare wheel cover delivers robust protection for your spare tire, using Mercedes’ proprietary Magno matte paint and thick, high-impact composite. It’s not just about style; the cover shields the tire from harsh outdoor conditions while showcasing AMG branding perfectly matched to your vehicle’s palette.
- Exact fitment for G-63 model years supporting these part numbers.
- Engineered mounting points for effortless installation using existing OEM fasteners.
- Premium materials with a non-fade, scratch-resistant finish unique to factory parts.
- Seamless integration with other interior/exterior AMG details for cohesive luxury.
In addition, you protect your G-63’s unique character with every genuine component.
OEM vs Aftermarket: Why Original Wins
In contrast, aftermarket parts often fall short in many ways. Even well-intentioned alternatives rarely replicate the engineering precision of Mercedes-Benz. Material quality, paint finish, and physical compatibility can vary wildly. This leads to unreliable fitment, mismatched colors, and a risk of premature deterioration.
Furthermore, only OEM parts like the Mercedes AMG G-63 Air Vent Trim Panels Rear Window Black OEM A4638691400 or Mercedes AMG G-63 Spare Wheel Cover Magno Green OEM A4638690800 retain full Mercedes warranty coverage. If you use a non-genuine part and something goes wrong, there’s a risk the manufacturer may deny coverage for related claims.
Consequently, resale value also depends on maintaining a full set of OEM parts, especially for collectors and discerning buyers.
Similarly, safety factors play a role. Factory parts are crash-tested as part of the complete G-Class assembly. Aftermarket parts rarely offer this peace of mind in critical areas.
Therefore, investing in OEM means investing in safety, durability, and the lasting prestige that defines the AMG ownership experience.
Installation Tips and Maintenance Best Practices
Because both the air vent trim and spare wheel cover are direct OEM replacements, installation is straightforward.
Before you begin, verify the part number matches your Mercedes AMG G-63 model year and trim.
Here are quick steps for each:
- Remove the worn or damaged part by carefully releasing OEM clips or fasteners, preserving hardware where possible.
- Align the new Mercedes AMG G-63 Air Vent Trim Panels Rear Window Black OEM A4638691400 or Mercedes AMG G-63 Spare Wheel Cover Magno Green OEM A4638690800 in place, ensuring tabs and fittings perfectly seat.
- Secure with OEM fasteners and double-check for gap-free, flush fitment.
Meanwhile, a soft microfiber cloth and non-abrasive automotive plastic cleaner help preserve the finish of your air vent trim.
As for the Magno Green spare wheel cover, avoid wax or polish—just use gentle soap and water to maintain the distinctive matte look.
Thus, using the right techniques ensures your parts stay flawless and factory-fresh for years.
