Engine cover for G63 AMG side parts Mansory Carbon for Mercedes G-class G500 / AMG G63 W463A

This is the side-cover pair that finishes what the centre plenum cover starts on the AMG G63 W463A. Sold as a mirror-matched left-and-right set, the side parts flank the M177 4.0 V8 biturbo plenum, dressing the inner-fender intake routing and the cam-cover edges that the central piece does not reach. They are part of the wider Mansory carbon programme catalogued under Mansory Carbon Body Kit for Mercedes G-class W463A G500/G63, and most owners specify them in the same order as the centre cover so the engine-bay theme reads as one continuous carbon canvas the moment the bonnet is lifted. Smaller surface area means weave alignment is more visible, not less — which is exactly why this pair is laid up by hand against the centre piece for symmetry.

Construction & Materials

The side covers are pressed in two handed moulds (LH and RH) that were taken from the same master used for the centre cover, so the weave runs continuously across all three pieces when the bonnet is open. Each shell is a sandwich of pre-preg 3K twill skins over a thin epoxy/aramid core, autoclave-cured under vacuum, then sealed with a heat-resistant clear lacquer rated for sustained engine-bay temperatures.

Because the parts sit close to cam covers and turbo heat shielding, lacquer chemistry matters more than on an exterior trim piece. The system used here is a two-component polyurethane clear with UV inhibitors and a glass transition that comfortably exceeds the steady-state air temperature behind a heat-soaked twin-turbo V8.

• Weave: 3K twill 2/2, mirror-flipped between LH and RH so the diagonals point inward toward the centre cover
• Lay-up: pre-preg skins, autoclave cure at controlled ramp, post-bake to relieve residual stress
• Wall thickness: roughly 1.6–1.8 mm at the visible face, locally thicker around clip bosses
• Weight: about 0.55–0.7 kg per side, ~1.2 kg for the pair
• Mounting: re-uses OEM plastic-cover clips on the strut tower and inner fender bosses, no drilling
• Finish: high-gloss clear lacquer as standard, satin and matte available on request
• Hardware: a small bag of replacement push-pins is supplied with each pair
• Edges: trimmed and flame-tipped so no raw weave is visible from any bonnet-up angle

Design & Visual Function

The function of the side parts is purely visual, but the geometry is anything but lazy. They follow the contour of the inner fender and the upper edge of the cam cover, hiding the painted plastic shrouds and the various wiring and hose runs that sit between the plenum and the strut tower. From the front of the car, with the bonnet up at a service angle, the eye reads a single continuous carbon panel from inner fender to inner fender; the centre cover hands off to the side cover at a precise mould break that lines up with a casting feature on the V8.

Because the parts are smaller than the centre cover, the weave alignment is easier to see — and easier to get wrong. Mansory therefore mirror-matches the LH and RH pair so that the twill diagonals converge symmetrically toward the centreline of the engine. When all three pieces are fitted, the weave reads as a chevron pattern that frames the V8 rather than a random patchwork of carbon panels. This is the kind of detail that does not show up in a single product photo but defines the whole bay once the bonnet is open at a show or a dealer event.

Light behaviour also changes with the lacquer choice. The standard clear gives the deep wet-look that most owners expect from Mansory carbon; the satin option dulls the highlights so that the weave geometry reads more strongly than the gloss, useful on cars where the rest of the engine bay has been finished in matte black wrinkle paint or anodised hardware.

Compatibility & Fitment

This pair is built for the Mercedes-Benz G-class W463A generation (2018+, the fourth-generation platform — note that W463A is the Mercedes internal code for the new car, not the old box). Within W463A the side covers fit the AMG G63 only, because the M177 4.0 V8 biturbo has a specific plenum and cam-cover geometry that the moulds reference. Non-AMG variants — G500, G550, G350d, G400d — use the M256 inline-six or OM656 diesel and are a different shape under the bonnet, so this part is not applicable to those engines.

Pre-2018 W463 (the original "boxy" G-Wagen, 1979–2018) is mechanically and dimensionally different and is not compatible. W463A Gronos and W465 use their own engine-bay programmes. LHD and RHD G63s share the same plenum and cam-cover layout, so the side cover pair fits both steering configurations without modification. Cars with or without the AMG ceramic brake option are equally compatible.

Installation & Reversibility

Fitting the pair takes a single technician about 25–35 minutes once the centre cover is on the bench. Each side part lifts onto the existing OEM clip points; the original plastic shroud is unclipped, lifted clear, and the carbon side panel is pressed down until each clip seats with an audible click. No adhesives, no drilling, no cutting of harnesses. The fasteners are the standard Mercedes push-pins used elsewhere on the engine plenum, and a fresh set is supplied in the box in case any of the originals have aged.

Reversibility is total. To return the bay to factory you simply pull the carbon panels off the clips and re-fit the OEM plastics — there is no permanent modification. We recommend that fitment is carried out at a Mercedes-AMG service centre, a Mansory-trained installer, or any competent body shop with experience handling pre-preg carbon trim. The risk during fitment is purely cosmetic — a fingerprint on uncured wax, a clip pressed at an angle — and is fully avoidable with clean gloves and a torque-free push-down approach.

Pairing within the Mansory G-class W463A G500/G63 programme

The side covers are designed as a deliberate companion to the centre piece and to the bonnet hardware sitting directly above them. The most common pairing in this engine-bay theme is:

• Engine cover for G63 AMG (centre piece) — the matching plenum cover; this pair was made to flank it and the weave is mirror-matched to it
• Air outtake for engine bonnet — the functional vent above the engine; once the bonnet is closed, the outtake reads as the visible signature of the carbon bay underneath
• Engine bonnet III — the carbon bonnet sitting directly over the assembly; specifying it together means the bay theme continues from the engine to the closed exterior surface

This is the "completes the engine-bay theme" combination — when the bonnet is lifted at a meet or a delivery handover, the carbon canvas reads from inner fender to inner fender, and from cam cover to bonnet inner skin, as a single coordinated piece of work.

Maintenance & Durability

Engine-bay carbon lives a different life to exterior carbon. The threats are heat cycling, the occasional drip of coolant or screenwash, and contact damage during routine servicing. The lacquer used here resists all three within sensible limits, but a few habits keep the pair looking new for a decade.

Wipe the panels with a soft microfibre after any garage visit — fingerprints on warm lacquer leave shadows that take longer to remove later. For deeper cleaning use a pH-neutral interior detail spray; avoid solvent cleaners, ammonia-based glass sprays, and citrus degreasers, all of which can soften or haze the clear coat over time. A light coat of carnauba or a long-life polymer sealant once or twice a year keeps the gloss deep and the surface easy to wipe. Avoid pressure-washing the engine bay with the bonnet open; the lacquer is robust but the goal is to keep water out of the harness and the alternator, not to test the carbon.

Heat is a non-issue at idle and on the road, but during track sessions or extended high-load running the surface can reach temperatures that soften most consumer waxes. Switch to a high-temp polymer or ceramic for those use cases. Chip repair on a side cover is feasible but rarely necessary because the parts are tucked behind the bonnet line and not exposed to road debris.

Lead Time & Warranty

Standard lead time for the LH+RH pair is 2–4 weeks from order, depending on lacquer choice and current production queue. Satin and matte finishes typically add a few days because they are sprayed and flashed separately from the gloss line. The pair ships in a single carton, each side wrapped individually and pre-fitted with its replacement clip set.

Warranty is 12 months against manufacturing defects — delamination, voids, fitment issues against the centre cover, or lacquer failure under normal engine-bay conditions. The warranty does not cover impact damage during installation, exposure to non-approved chemicals, or modifications carried out after fitment.

FAQ

Q: Are the side parts sold individually or only as a pair?
A: Only as a mirror-matched pair. They are laid up together to guarantee weave symmetry across the full LH–centre–RH set, and selling singles would break that match.

Q: Will they fit a G500 or G350d?
A: No. The moulds reference the AMG M177 plenum and cam-cover geometry. Non-AMG W463A variants use a different engine and would not match.

Q: Do they require the centre engine cover to be fitted as well?
A: Strictly speaking they will fit on their own, but the visual effect is built around the mirror-matched chevron with the centre cover. Most owners specify both at the same time.

Q: What lacquer finishes are available?
A: Gloss as standard, with satin and matte available on request. The carbon weave is the same on all three; only the clear coat changes.

Q: Will the heat from the V8 yellow the lacquer over time?
A: The clear used here is a two-component polyurethane with UV stabilisers and a glass transition above sustained engine-bay temperature. Under normal road and occasional track use it stays clear for the lifetime expected from a premium carbon part.
