Engine cover Mansory for Mercedes-AMG S63E
Mansory Engine Cover for Mercedes-AMG S63E
The first thing anyone sees when the bonnet is opened on a flagship AMG saloon is the engine cover that drapes the V8. Mercedes-AMG's OEM cover is a moulded plastic acoustic shroud — competent, factory-correct, but visually inert. The Mansory carbon engine cover replaces it with a structural carbon shell that re-frames the open-bonnet view of the AMG biturbo V8 in the Mansory carbon palette. It is the part that completes the under-hood programme — the front bonnet handles the upper exterior plane, the engine cover handles what is exposed when that bonnet is opened. On a 2,510 kg long-wheelbase W223 saloon running an AMG biturbo V8 PHEV with 802 hp / 1430 Nm peak output and a 13.1 kWh HV battery integrated into the powertrain architecture, the engine bay is the most thermally complex and visually busy on any current AMG product, and a coordinated carbon plane across the V8's centre brings visual order to it. It is part of the parent Mansory Carbon Fiber Body kit set for Mercedes-AMG S63E.
Construction & Materials
The engine cover lives in a hot zone over the V8's intake plenum. Layup uses an elevated-Tg resin system rated for sustained engine-bay temperatures and a substrate prep that resists oil-mist contamination during long-term service.
- 3K 2×2 twill A-side cosmetic skin (forged-look option, 2K plain weave option)
- Inner stiffener ribs in unidirectional carbon to resist warping under heat cycling
- Pre-preg vacuum-bag autoclave cure at 145 °C peak with 80 °C dwell, multi-axial fibre orientation
- Wall thickness 1.8–2.4 mm in the show face, 3.0–3.5 mm at the OEM mount points
- Net dry weight 1.5–2.0 kg (vs ~2.0–2.5 kg for the OEM acoustic shroud)
- OEM-style ball-and-socket mounts at factory cover-stud positions, no drilling
- Heat-resistant 2K clear lacquer with high-Tg topcoat for engine-bay duty
- Substrate prep: degreaser wipe, IPA, primer; OEM acoustic foam strips transfer to the cover underside
Design & Visual Function
The cover's geometry tracks the OEM AMG cover's external silhouette so the engine bay's layout does not look interrupted; what changes is the surface finish and the embedded AMG-style branding. The 3K twill is biased so the diagonals run forward — toward the windscreen — pulling the eye out of the engine bay and toward the cabin, which is appropriate for a luxury saloon where the engine bay is admired briefly rather than staged for photography. The cover's centre carries a subtly recessed branding badge (carbon-on-carbon emboss rather than chrome) that aligns with the AMG-spec emblem position.
Functionally the cover continues the OEM acoustic role — the original under-cover foam strips transfer to the carbon piece's underside during installation, so cabin NVH at idle and at sustained motorway speed is not affected. Engine-bay heat does not soak the carbon cover the way it soaks an aluminium piece; the elevated-Tg resin is rated for sustained 110 °C surface temperature with no warp or yellowing.
For owners who specify an AMG Carbon Package interior trim line, the gloss lacquer over 3K twill matches the AMG-supplied carbon palette in the cabin. For AMG Night Package cars, a satin lacquer is the natural pairing, although the engine-bay lighting is rarely strong enough to make the satin/gloss distinction visually dominant.
Compatibility & Fitment
Engineered for Mercedes-AMG S 63 E PERFORMANCE (W223), 2023+, saloon. The OEM AMG ball-and-socket cover-stud positions are the mounting datums; no chassis modification is performed and no fastener is added. The cover does not interact with the AMG biturbo V8's intake plenum, the OEM oil-fill cap, the dipstick housing, or any sensor under the cover. The ball-and-socket interface allows for the small thermal expansion the cover undergoes between cold-start and steady-state running. The PHEV-specific HV battery sub-cover (where fitted in the engine-bay layout) is not part of this product and remains in OEM specification.
Installation & Reversibility
Plan 15–25 minutes. Required tools: torque-screwdriver if the OEM cover is held by torque-to-yield fasteners, plastic trim picks for ball-and-socket release, isopropyl alcohol for cleaning the OEM acoustic foam strips before transfer. Workflow: lift the OEM cover off its ball-and-socket mounts, transfer the OEM acoustic foam strips to the carbon cover's underside (the strips have factory adhesive that releases cleanly), drop the carbon cover onto the OEM ball-and-sockets, press home until each socket clicks. Reversibility is full — the OEM cover reseats on the same ball-and-sockets at any time. No drilling, no permanent bonding, no chassis modification.
Pairing within the Mansory Mercedes-AMG S63E programme
The engine cover pairs naturally with the Front bonnet directly above (so the open-bonnet view shows a coordinated carbon palette top and centre), with the Engine bonnet emblem on the bonnet centre, and with the Sport outtake for front fender so the carbon palette continues outward from the engine bay through the side fender vent.
Maintenance & Durability
The engine cover is reachable only when the bonnet is open, so cleaning happens during scheduled service rather than on the wash. Wipe down with an automotive interior cleaner and a soft microfibre when the engine is cold; avoid solvents (brake cleaner, panel wipe) which will dull the high-Tg topcoat over months. Oil-mist contamination from a long-running rocker-cover gasket leak should be cleaned promptly with a dilute degreaser at 1:10 followed by IPA and a final dry microfibre — letting oil mist soak into the lacquer for a season will eventually leave a visible haze. The high-Tg topcoat is rated for sustained 110 °C surface temperature; under-bonnet temperatures during normal road use are below that envelope. Lifespan: 12+ years cosmetic finish under normal service. The OEM acoustic foam strips on the underside should be inspected at every other service for compression-set or oil contamination.
Lead Time & Warranty
Production turnaround: 3–5 weeks. The high-Tg topcoat ramp adds time relative to a body-only carbon part; custom finishes (matte, satin, forged-look) extend by roughly one week. Warranty: 12 months against manufacturing defects — delamination, voids, fitment, clear blistering, heat-induced surface degradation — running from delivery date. Outside warranty: oil-mist staining, chemical degradation from solvent contact, impact damage from dropped tools. Each cover ships in a foam-lined carton with the QC photograph documenting weave alignment and high-Tg topcoat continuity under raking light.
FAQ
Q: Does the cover affect engine-bay cooling?
A: No. The cover sits at the same height and silhouette as the OEM acoustic shroud and does not change air-flow paths around the AMG biturbo V8's intake plenum or the auxiliary cooling pack at the front of the bay.
Q: Will the carbon discolour over time from engine-bay heat?
A: Not under normal road use. The high-Tg topcoat is rated for sustained 110 °C surface temperature; the open-bonnet surface temperature on an S 63 E PERFORMANCE under normal road use sits comfortably below that.
Q: Does the OEM acoustic role transfer to the carbon piece?
A: Yes. The OEM acoustic foam strips on the underside of the original cover transfer to the carbon piece during installation and continue to perform their NVH role at idle and sustained speed.
Q: Is the AMG-style branding badge included?
A: Yes — a recessed carbon-on-carbon emboss, aligned with the OEM emblem position. Owners who prefer the OEM chrome AMG badge can swap it onto the carbon cover during installation; a clean transfer protocol is documented in the supplied installation note.
Q: Will the cover fit cars with the AMG Carbon Package interior?
A: Yes — and the gloss-lacquered 3K twill on this cover is selected to coordinate visually with the AMG-supplied cabin carbon trim.
Q: Does the cover interfere with HV-battery service access?
A: No. The HV-battery service points on the W223 PHEV layout are accessed from elsewhere on the chassis and are not under the engine cover.
Q: Does the carbon cover affect engine NVH at startup?
A: No. The OEM acoustic foam strips transfer to the carbon piece's underside, so the cabin acoustic profile at cold-start, idle, and sustained motorway speed is unchanged.
Q: Is the cover compatible with aftermarket engine accessories?
A: Most aftermarket accessories that sit below the OEM cover height — strut braces in particular — are unaffected. Tall aftermarket air-filter housings or above-rocker-cover oil catch tanks may require either trimming or relocation; the production envelope of this part is the same as the OEM cover.
Q: Does the cover withstand a routine engine-bay clean?
A: Yes, with a dilute (1:10) automotive-grade interior cleaner and a soft microfibre at engine-cold conditions. Avoid steam cleaning, brake cleaner, and any aggressive solvent — they will dull the topcoat over months.
