Air outtake cover Mansory Carbon for Mercedes GLS X167
Air Outtake Cover Mansory Carbon for Mercedes GLS X167
The Mansory carbon air outtake cover is the outer surround that frames the functional rear-quarter air outlet on the Mercedes-Benz GLS X167 — the panel that turns a stamped OEM louvre into a piece of coachbuilt carbon jewellery. Within the wider Mansory programme catalogued under the Mansory Body Kit for Mercedes GLS X167, this cover is the part that signs the rear flank: it sits behind the front wheel-arch on the body side, hugging the OEM vent aperture, and reads as a small but theatrical detail when the GLS rolls past on its 4MATIC stance. Specified by owners of GLS 450, GLS 580 and AMG GLS 63 alike, it works whether the rest of the car is restrained executive or full Mansory wide-arch theatre.
Construction & Materials
The cover is laid up as a one-piece carbon shell, contoured to mirror the OEM vent’s surrounding bodywork curvature so the panel sits flush against the wing pressing rather than floating proud of it. Mansory’s standard finish is a deep-gloss UV-stable lacquer over 3K twill weave, with a forged-look or 2K plain-weave option available to match other panels already on the car.
- Layup: pre-preg twill, 3K (2K plain or forged-look on request) — weave aligned to follow the rocker line and keep the diagonal continuous with adjacent Mansory panels
- Cure: autoclave-cured at controlled ramp, post-cured for dimensional stability through the GLS’s temperature swings
- Wall thickness: ~1.6–2.0 mm with reinforced edge return where the panel wraps the vent perimeter
- Mass: ~280–340 g per side (cover only) — a non-event next to the X167’s ~2.49 t kerb weight, but the bond surface stays inside OEM body-flex tolerance
- Mounting: 3M VHB structural double-sided tape on the main bond face plus discreet OEM-style retention clips at the inner edges, so the panel cannot creep over thermal cycles
- Finish: deep-gloss Mansory lacquer with full UV-block clear, resistant to yellowing through normal SUV use
- Hardware: stainless / EPDM-gasketed clips, no exposed fasteners on the visible face
- Edge treatment: chamfered and lacquer-wrapped so weave terminations are sealed against UV, water ingress and stone-chip propagation
Design & Visual Function
The rear-quarter air outlet on the GLS X167 is a real feature, not a styling decal — it vents engine-bay and wheel-arch pressure out behind the front wheel and gives the body side a sense of motion. Mercedes’ OEM treatment is restrained chrome-and-black; Mansory replaces that surround with a sculpted carbon frame that picks up the visual rhythm of the rest of the wide-body programme. The cover is the OUTER element — the surround that rings the vent and ties it to the surrounding wing — and it is deliberately kept distinct from the air-outtake splitter, which is the INNER divider fin that bridges the opening. Together the two parts make a complete carbon air-outlet treatment; specified individually they each still upgrade the area, but most owners take the duo because the visual logic only fully reads when the surround and the inner fin are both present.
Weave alignment matters here more than on a flatter panel. The cover wraps a compound curve where the wing rolls into the door shut-line, so Mansory align the 3K twill diagonal to follow the rocker line and continue uninterrupted into the front-fender-panel and fender-extension flares. Viewed from three-quarter rear, the eye reads one continuous carbon stripe from arch flare through vent to door — the GLS’s long flank, normally interrupted by chrome trim, is unified.
Trim-level differentiation is genuine. The AMG GLS 63 vent geometry is subtly different from the standard GLS / GLS 580 — the Panamericana-grilled AMG runs a slightly more aggressive aperture profile, and Mansory’s cover is supplied tooled to the correct variant for your VIN. Specify trim at order time so the cover lands flush rather than approximately. The visual outcome on either trim is the same: the OEM vent stops looking like a parts-bin louvre and starts looking like a Mansory-bespoke detail.
Compatibility & Fitment
Designed for the Mercedes-Benz GLS X167 from 2019 onward — covering GLS 450 (3.0L inline-6 with EQ Boost mild-hybrid), GLS 580 (4.0L V8 BiTurbo, 4MATIC) and AMG GLS 63 (4.0L V8 BiTurbo, ~603 hp, four central-mounted exhausts, Panamericana grille). Both pre-facelift and post-MY2024 facelift bodies are catered for; the cover is tooled per body shape and per trim variant and the correct version is shipped against your VIN. The OEM vent’s functional opening is fully retained — airflow path is unchanged, parking-sensor cones nearby (where present) are not interrupted, and AIRMATIC self-levelling has no clearance interaction with the panel since the cover sits high on the body side.
Installation & Reversibility
This is one of the friendlier Mansory parts to install. Total time is 45–60 minutes per side for a competent home installer, longer if you want a perfect bond cure. Workflow: remove protective film from OEM surround, IPA-clean the bond face on the body, dry-fit the carbon cover and confirm gap-and-flush at all four edges, peel the 3M VHB liner, present the panel to the body with the inner clips engaging first, then press home along the bond line and hold for the manufacturer-recommended initial cure window. Final cure is reached over 24–72 h depending on ambient temperature — keep the car out of a pressure-wash for the first three days. Reversibility is straightforward: warm the bond line with a heat gun, fishing-line through the VHB, peel the cover, residue-clean the body. No paint damage if the work is done patiently. DIY is fine for owners who have done VHB-bonded trim before; otherwise any Mercedes-certified body shop or Mansory-trained installer can fit it inside an hour.
Pairing within the Mansory GLS X167 programme
The most natural sibling is, by design, the inner divider — Air Outtake Splitter Mansory Carbon for Mercedes GLS X167. The cover frames the vent; the splitter divides it. Specified individually, each part is a discrete carbon upgrade; specified together as a duo, they finish the air outlet completely and the area finally reads as a coherent Mansory detail rather than two-thirds of a treatment. We strongly recommend ordering both at the same time to ensure the lacquer batches match exactly.
From there, owners typically widen the carbon flank treatment with the Fenders Extension Mansory Carbon for Mercedes GLS X167, which carries the carbon line from the vent surround out over the wheel arches, and the Front Fender Panel Mansory Carbon for Mercedes GLS X167, which ties the front wing into the same weave-and-finish family. Together those four parts — cover, splitter, fender extension, fender panel — complete the body-side carbon programme without committing to a full wide-body conversion.
Maintenance & Durability
Lacquered carbon on a body-side panel sees road film, stone strikes from the front wheel and occasional jet-wash pressure. Keep care simple. Two-bucket wash with a pH-neutral shampoo, clean microfibre, no alkaline degreaser anywhere near the lacquer. Avoid ammonia-based glass cleaners on adjacent panels because over-spray dulls the clear over time. A high-quality ceramic coating layered over the lacquer is the right call — it gives the carbon a sacrificial barrier against the gritty water that flicks off the front tyre into the vent area. Carnauba is fine but needs more frequent renewal. PPF over the leading edge of the cover is worthwhile if the GLS sees motorway miles or gravel tracks, since the cover sits in the strike line of debris thrown back by the front tyre. Repair workflow: minor lacquer chips can be wet-sanded and re-cleared by any decent body shop; deeper weave damage is panel replacement, not field repair, and Mansory keep tooling for the X167 programme so a replacement is always available — albeit on the standard 4–8 week production cycle.
Lead Time & Warranty
Lead time is 4–8 weeks from order confirmation, in line with Mansory’s bespoke production cadence — every cover is laid up, cured and finished against your specific order rather than pulled from stock. The part carries a 12-month manufacturer warranty against material and workmanship defects. We confirm your VIN, trim (450 / 580 / AMG GLS 63) and preferred finish (gloss 3K twill, gloss 2K plain or forged-look) at order so the correct tooling and lacquer batch are scheduled.
FAQ
Q: Cover or splitter — if I can only specify one, which goes first?
A: The cover. It frames the entire vent and is the more visible element from a normal viewing distance. The splitter then completes the duo and is the upgrade we recommend within a few months — the lacquer batches age in step if both are ordered together, but ordering the splitter later is fine, just specify the same finish.
Q: Will it fit my GLS 450, my GLS 580 and my AMG GLS 63 the same way?
A: Same fitment family, but the AMG GLS 63 has slightly different vent geometry from the standard / 580 cars, so the cover is supplied tooled to the correct variant against your VIN. Confirm the trim at order; the part lands flush on whichever spec you run.
Q: What finish should I pick?
A: Gloss 3K twill is the default and matches the rest of the Mansory GLS X167 programme out of the box. Gloss 2K plain reads a touch more formal and pairs well with restrained executive specs. Forged-look is the loudest option — pick it only if other panels on the car are already forged-look.
Q: Does it block the OEM vent or interfere with airflow?
A: No. The cover is a surround — it rings the OEM aperture without restricting it. Engine-bay and wheel-arch pressure venting is unchanged. Parking sensors near the area, where fitted, are not in the bond zone and continue to operate normally.
Q: Lead time and what happens if I damage it after fitting?
A: Production runs 4–8 weeks. If a panel is chipped or stone-struck after fitting, minor lacquer damage is repairable at any decent body shop; deeper weave damage means a replacement, on the same 4–8 week cycle. The 12-month warranty covers manufacturing defects, not impact damage.
Pair the cover with the air-outtake splitter to finish the rear-quarter vent properly, and keep the carbon line continuous along the flank with the fender extensions.
