Air outtake cover - side skirt Mansory Carbon for Lamborghini Aventador S

Mansory Carbon Air Outtake Cover (Side Skirt) for Lamborghini Aventador S

The side-skirt outtake cover is a louvred carbon panel that sits low on the rocker line of the Aventador S, between the front wheel arch and the side-skirt-lip transition. Its job is unglamorous and important: it lets hot air leave the chassis sideways, low and downstream of the front wheel, instead of stagnating around the lower flanks of the naturally aspirated 6.5-litre V12. Within the wider Mansory Body Kit for Lamborghini Aventador S programme it is a quiet, technical specification — chosen by owners who already run the lip-and-diffuser combination and want the rocker line to read as a working surface rather than as smooth bodywork. Aventador S has no ALA, so there is no active flap logic to honour here; the cover is a passive louvre, sized for the LP740-4 S monocoque cutouts and respecting the lower-side exhaust outlets a few centimetres aft.

Construction & Materials

The piece is laid up as a multi-ply prepreg CFRP shell with an inner sub-frame that carries the louvre slats. Mansory uses a 3K twill outer skin so the diagonal weave reads cleanly against the satin of a painted skirt or the matte of a bare-carbon skirt. The louvre fins are moulded as a single carbon assembly rather than bonded individually, which keeps the gap geometry consistent across the part — a detail that matters when light catches the rocker at low angles and the fins act as a row of small shadow lines.

• Outer skin: 3K twill prepreg, lacquered or matte at order time
• Inner louvre cassette: moulded as one CFRP module, not bonded slats
• Cure: autoclave, controlled ramp, post-cure for dimensional stability
• Wall thickness: 1.6–1.9 mm on the outer panel, 1.3 mm at the louvre webs
• Mass: roughly 0.55–0.7 kg per side as a finished assembly
• Fastening: factory studs from the OEM skirt cutout, plus a strip of high-shear methacrylate adhesive
• Finish options: clear lacquer, satin lacquer, matte, or paint-break two-tone
• UV stability: cosmetic-grade lacquer system rated for prolonged sun exposure

Design & Visual Function

The Aventador S rocker is a long, mostly horizontal element that ties the front intake region to the rear-wheel-steering arch. Without a louvre break it can read as a single uninterrupted slab of paint. The Mansory outtake cover injects a measured visual rhythm — a row of carbon fins angled rearwards — which echoes the hexagonal language Lamborghini uses on the bumpers and the engine bay. The fins are pitched so that, viewed from the kerb at standing height, they read as solid carbon; viewed from a lower, photographic angle they reveal the cavity behind, which is exactly the impression most owners want.

Functionally the cover serves a thermal role. The Aventador S V12 is dry-sumped and its oil cooling, gearbox cooling and engine-bay extraction all push hot air outwards through under-skirt channels. The factory skirt area is largely closed at this point on the car, which means hot air that has done its job around the gearbox has limited route out. The Mansory louvre opens a low-pressure exit path that vents this heat sideways, downstream of the front wheel where it is dragged clear by the wake. That keeps the rocker carbon a few degrees cooler under sustained load and reduces the heat soak felt by the lower section of the side window glass and the inner door card.

The third design dimension is paint break. Because the cover sits inside the skirt cutout, owners specify it either body-coloured (so the louvre is the only carbon element on the rocker), bare-carbon to match the side-skirts-lip in a continuous carbon strip, or as a two-tone where the surround is paint and the louvre fins are clear-lacquered weave. All three work, and Mansory paint shop will book in any of them as a single line item.

Compatibility & Fitment

The cover is engineered for the Lamborghini Aventador S (LP740-4 S) in coupé and Roadster trim, build years 2017–2021. Pre-SVJ bumper geometry and lower-side exhaust outlets are respected — no fouling on the exhaust shrouding aft of the cover, and no contact with the OEM rear-wheel-steering loom that runs along the inboard side of the skirt. There is no ALA on Aventador S, so the cover does not need to be coordinated with active aero hardware. OEM parking-sensor plumbing is untouched because the cover sits forward and below of the rear sensor cluster.

Installation & Reversibility

Allowed time on a hoist is 60–90 minutes per side for a careful installer; faster on a second pair of hands. The skirt cutout uses factory studs from the OEM panel as the primary location, and a strip of methacrylate adhesive runs along the upper rail to take shear load. Methacrylate is the right chemistry here because the Aventador's CFRP monocoque uses methacrylate bonds elsewhere on body panels, and the cure characteristics match what a Lamborghini-trained body shop will already have on the bench. Reversibility is acceptable: if the cover is removed, the OEM skirt section is intact behind it because the cover is additive, not destructive — no cutting into the skirt, no enlarged apertures, no welding. We recommend a Mansory-trained installer for the bonded element, but the mechanical alignment is straightforward enough that an experienced detailer can dry-fit and verify panel gaps before the bond cures.

Pairing within the Mansory Aventador S programme

The natural sibling on the same rocker is the Mansory side skirts lip: lip below, outtake cover above, and the rocker reads as a deliberate carbon stripe that runs the full length of the door. Owners who specify both usually go bare carbon on the lip and matte black on the louvre, or the inverse, so the two pieces don't compete for attention. The other functional pairing is the side-window air intake: that part feeds the V12 airbox and oil-cooler region above the door line, the side-skirt outtake exhausts engine-bay heat below it, and together they describe a complete thermal flow path along the flank. For owners who also run the rear bumper air outtake cover, the side-skirt louvre extends the same visual grammar of fins and slots from the rocker round to the rear bumper corner — a coherent rear-three-quarter when the car is photographed.

Maintenance & Durability

The lacquer system on the outer skin is the durable surface; the louvre fins are slightly more exposed and will collect road film on the leading edges. A pH-neutral shampoo and a soft microfibre is the only correct toolkit. Alkaline degreasers, ammonia-based glass cleaners that drift over from the side window and abrasive sponges all kill clear-lacquered carbon — they cloud the lacquer first and then etch the resin underneath. Ceramic coating is appropriate, applied warm and cured indoors; carnauba wax is fine on the outer skin but pointless on the louvre fins because it loads up between the fins and gets photographed as wax residue. Stone-chip risk is concentrated on the leading edge of the cover where the front wheel throws debris; a clear paint-protection film strip along that edge, hand-cut so it doesn't extend over the louvre slots, is the recommended specification for a daily-driven car. Lifespan of the moulded louvre is decades for a garage-kept car. Any chip on the visible weave can be repaired by a carbon-trim specialist using a fill-and-flat-back lacquer technique without needing the panel removed.

Lead Time & Warranty

Lead time is typically 4–8 weeks from order confirmation, reflecting Mansory's bespoke production cadence and the fact that the louvre cassette is moulded to order in the chosen finish. The part carries a 12-month warranty against manufacturing defects on the outer skin and the louvre cassette. We coordinate paint-match against your VIN colour code for any body-coloured surround at no extra step.

FAQ

Q: Does the cover fit Aventador S Roadster as well as the coupé?
A: Yes. The skirt panel is shared between coupé and Roadster on the LP740-4 S, and the cover is identical for both bodystyles.

Q: Will it foul the lower-side exhaust on the Aventador S?
A: No. The cover sits forward of the exhaust outlet and the louvre vents air sideways, not rearwards into the exhaust path. Heat shielding inside the skirt is undisturbed.

Q: How much weight does the pair save versus the painted skirt section it replaces?
A: The cover is additive rather than a direct swap, so the headline number is small — typically 0.4–0.6 kg net once the cosmetic body-shop fill behind the cutout is removed. The point of the part is thermal and visual, not weight reduction.

Q: Bare weave or lacquered weave for the fins?
A: We recommend lacquered for any car that sees rain or salt; bare matte is gorgeous on a garage-queen but the resin oxidises faster on the leading edges of the louvre. Most owners specify a clear satin lacquer that reads as raw weave at three metres.

Q: Is the louvre angle adjustable, like a vent register?
A: No. The fin angle is moulded as part of the cassette and tuned by Mansory aero for the Aventador S rocker pressure field. There is no field adjustment, by design — fixed geometry keeps the visual rhythm consistent.

Q: Can the cover be installed alone, or must it be ordered with the side-skirts-lip?
A: It can be installed standalone. Many owners specify the cover first, drive it for a season, then add the lip when they next book the car for a wheel-off detail. Both specifications can also be ordered together for a single fitment visit.
