Mansory Middle Air Vent Cover — Dashboard-Centre Carbon Bezel for Mercedes-Benz G-Class W465 Gronos
The Mansory Middle Air Vent Cover is the carbon bezel that sits in the dashboard-centre position of the W465 Gronos cabin — the twin-vent stack directly above the central control display, between the driver and front passenger. It is one of the most-looked-at surfaces in the cabin: the eye is naturally drawn to it whenever the climate control is adjusted, whenever a phone is mounted on the central console, whenever the driver glances at the screen. Because of that visual prominence, Mansory treats this bezel as one of the signature interior parts of the Gronos package, and it is engineered to a level of finish that exceeds the surrounding OEM trim.
Where It Sits — Dashboard-Centre Vent Positioning
The W465 dashboard architecture places three air-vent zones across the upper trim line: the driver-side outboard, the dashboard-centre pair (this part), and the passenger-side outboard. The middle position is structurally and visually different from the outboard pairs — the centre stack carries two circular vent units mounted in a single horizontally elongated bezel, and that bezel forms the visual bridge between the upper instrument hood and the screen surround below. Mansory's middle vent cover replaces the OEM piano-black or brushed-aluminium bezel with a single piece of pre-preg carbon, with the two vent rings inset and the directional vane assemblies retained from the OEM unit (or upgraded to anodised aluminium, depending on the option chosen).
Materials — Carbon Shell, Aluminium Vanes, Optional Knurled Wheel
The bezel itself is laid up from 2x2 twill carbon pre-preg at approximately 200 g/m², with two visible plies on the outer face and additional structural plies on the back side around the mounting clips. The cure is run in an autoclave at 130°C with vacuum-bag consolidation, producing a void content well under 2% and a surface gloss that shows the twill weave deeply with no orange-peel artefact. The piece is finished with a high-build clear coat that is wet-sanded and re-polished to a true optical flat — there is no waviness across the bezel face when the cabin overhead light catches it.
The directional vanes inside each vent ring are machined from anodised aluminium rather than the OEM injection-moulded plastic. The anodising is run in a black colour-matched batch with the rest of the Gronos interior aluminium (including the door pull inserts and the steering-wheel paddle blanks if those are also fitted), so the visual tone is consistent across the cabin. The vanes are mounted on stainless pivot pins with PTFE-lined bushings, which is a meaningful upgrade over the OEM plastic-on-plastic pivot — the throw is silkier, the detent is more positive, and the vanes do not develop the slight rattle that plastic vent vanes can develop after a few thousand kilometres of dashboard vibration.
An optional knurled aluminium control wheel can be specified for the central thumb-wheel that opens and closes the vent. The OEM wheel is a smooth plastic disc; the Mansory option is a CNC-knurled aluminium puck with a tactile diamond pattern, anodised to the same tone as the vanes. It is a small detail, but it is the part of the bezel that the driver actually touches every time the climate setting changes, and the upgrade in tactile feedback is immediate.
HVAC Airflow Integrity — No Restriction, OEM Vane Throw
One of the engineering priorities for any aftermarket vent cover is that it must not compromise the HVAC system. The Mansory part is dimensioned so that the internal vent ring diameter and depth match the OEM unit to within ±0.3 mm, which means the airflow cross-section presented to the HVAC blower is unchanged. There is no measurable static-pressure penalty in the duct upstream of the bezel, and the cabin sensor that measures discharge temperature at the centre vent reads identically to a stock car of the same configuration.
The directional vanes retain the full OEM angular throw: ±35° from centre in the horizontal plane and ±28° in the vertical plane. This matches the original Mercedes vane specification exactly — the bezel is not a fashion piece that sacrifices function for form. It is engineered so that the climate system, including the auto-mode logic that biases airflow between the centre and outboard vents based on solar load and cabin temperature differentials, behaves identically to a factory car.
Fitment — W465 Gronos Centre Stack, Ambient-Light Compatibility
The bezel is dimensioned specifically for the W465 dashboard centre stack — the post-2024 G-Class architecture, not the W463A predecessor. The mounting clips are aligned to the W465 dashboard substructure, the rear-side cut-outs clear the W465 HVAC duct geometry, and the bezel face profile follows the W465 dashboard topography, which is subtly different from the W463A in the way the centre stack transitions into the screen surround.
The part is also compatible with the Mansory ambient-light upgrade kit for the W465 Gronos — there is a small light-pipe channel routed along the inboard edge of the bezel that accepts the ambient-light fibre, allowing the bezel perimeter to glow in the chosen ambient colour without disturbing the carbon weave on the outer face. If the ambient kit is not fitted, the channel is filled with a black-finished blanking strip that is invisible at normal viewing distance.
Installation — Clip-In OEM Retention, Optional VHB Backing
The standard installation method is OEM clip-in retention using the same six spring-clip locations that hold the factory bezel. The OEM bezel is removed by levering carefully along its lower edge with a plastic trim tool, the wiring harness for the central thumb-wheel illumination is unclipped, and the new Mansory bezel is presented to the dashboard and pressed home until all six clips engage. Total installation time is typically 20 to 35 minutes for a careful technician, and no special tools beyond a plastic trim-removal kit are required.
For owners who want additional retention security — usually because the vehicle is going to live on rough road surfaces, or because a previous owner has flexed the dashboard substructure and the spring clips no longer engage with full pressure — Mansory supplies an optional 3M VHB 5952 acrylic foam backing strip kit. This is a high-bond foam tape rated for automotive interior applications, applied along the back perimeter of the bezel before installation. It is reversible with careful heat-and-fishing-line removal, but it adds a substantial amount of pull-out resistance to the part. We recommend the VHB backing only when the OEM clips alone are not delivering a confident snap-fit.
Care — Microfibre and Isopropyl, No Solvents
The carbon bezel face requires no special maintenance beyond what the rest of the cabin trim receives. Dust is removed with a clean, dry microfibre cloth. Smudges from fingerprints — which appear most commonly around the central thumb-wheel area — are cleaned with a microfibre lightly dampened with isopropyl alcohol diluted to roughly 70% in distilled water. We advise strongly against any cleaning chemistry that contains acetone, MEK, ammonia, or strong solvents — these can attack the clear coat over the carbon and cause hazing. The anodised aluminium vanes are cleaned in the same way; the anodising is durable but should not be scrubbed with abrasive pads.
Position Within the Parent Mansory Gronos Kit
The middle air vent cover is one of approximately a dozen interior carbon and aluminium parts within the broader Mansory body and interior kit for the W465 Gronos. It pairs naturally with the outboard vent covers (for full vent-stack consistency across the dashboard), with the steering-wheel carbon spoke covers, with the door-pull carbon inserts, and with the centre-console armrest carbon top. It is one of the most cost-effective single-part upgrades in the catalogue because it is a high-visibility area of the cabin and the weave is constantly in the driver's field of view, so the visual impact-per-euro is very high.
For owners who are building up the interior carbon package piece by piece rather than committing to the full kit at once, this bezel is one of the parts we suggest as a first or second purchase, immediately after the steering-wheel carbon if that is being specified.
Ordering — WhatsApp and Email, VIN Verification on Request
To order or to discuss specification options — vane finish (OEM-retain or anodised aluminium upgrade), control-wheel finish (OEM or knurled aluminium), ambient-light channel preparation, and VHB backing inclusion — contact us via WhatsApp +44 7488 818 747 or [email protected]. We can verify fitment against the vehicle VIN on request, which is the recommended approach if the dashboard architecture has been updated mid-cycle by Mercedes — VIN verification eliminates any risk of receiving a part for the wrong dashboard substructure.
FAQ — Common Pre-Purchase Questions
Will this bezel interfere with the HVAC discharge-temperature sensor?
No. The HVAC sensor that reads centre-vent discharge temperature is mounted on the duct side of the vent ring, upstream of the bezel face, and is not touched during installation. Because the internal duct cross-section is preserved, the sensor reads the same temperature it read with the OEM bezel, and the auto-mode climate logic continues to balance airflow between centre and outboard vents using the unchanged sensor signal.
Does the bezel work with the Mansory ambient-light upgrade?
Yes — the bezel is designed with an internal light-pipe channel along its inboard edge that accepts the ambient-light fibre. If you are specifying both parts together, request the ambient-prepared bezel variant. If you are not running the ambient kit, the channel is closed with a black-finished blanking strip that is visually invisible.
How is the bezel removed if I need to refit the OEM part later?
The bezel removes by reversing the installation procedure — lever gently along the lower edge with a plastic trim tool, disengage the six spring clips one by one, and lift the bezel away. If the optional VHB backing has been used, removal additionally requires gently working a fishing line behind the bezel with mild heat from a hairdryer to release the acrylic foam. The OEM bezel can then be re-clipped into place using its original retention.
What is the typical lead time?
Stocked configurations (gloss 2x2 twill carbon, OEM-retain vanes, no VHB backing) typically ship within 2 to 3 weeks. Configurations with anodised aluminium vanes, knurled control wheel, or matte clear coat are made to order with a lead time of approximately 5 to 7 weeks. We confirm exact availability at quote stage.
