Spoilers redirect air upwards at the trunk's trailing edge. As air flows upwards, counterforce on the spoiler pushes it, the trunk lid, and entire rear of the vehicle downward. Racecars are all equipped with deck lid spoilers of various sizes because this downward force means more grip for rear tires around turns at high speeds. As modern vehicles have become better engineered and capable of higher speeds, trunk lid spoilers have become commonplace for both their function and for their beauty. Whether you want to replace a factory spoiler or add one, you're looking to make your vehicle a better version of itself and now CARiD lets you do that with the Trunk Lid Spoiler from Aero Function. Should you wish to match your vehicle's body color, we recommend priming and painting before installation.

Advanced computer aided design and high-tech manufacturing processes ensure all Aero Function components fit evenly against every panel and contour of your specific make and model. Once parts have been prepped and installed on your vehicle, they achieve a look that matches the quality of original equipment without the gaps, uneven edges, and poor visual continuity that plague parts from inferior competitors. Depending on vehicle application, components may be produced from carbon fiber plastics, fiberglass composites, or polyurethane polymers. Aero Function is well-respected throughout the industry for the development of each of these lightweight composite materials which feature extremely high levels of strength, rigidity, and superior impact absorption. Even under the harshest climates and conditions, Aero Function parts have proven their ability to maintain integrity without warping or cracking for long periods of time. Add-on aero pieces can be installed using any method of your choice such as double-sided tape or weather stripping adhesive, and Aero Function backs what they build with a 3-year warranty against defects.

Founded in the late 1990s in Fullerton, California, Aero Function is part of the Extreme Dimensions group of premiere automotive parts manufacturers. Drawing on a wide pool of engineering talent, Aero Function specializes in producing aerodynamic accessories for high end luxury vehicles made from advanced composite polymers they have developed in house. Aero Function is known worldwide for their carbon fiber plastics (CFP), handmade fiber glass composites, and Pur Rim polyurethane plastic composites that set industry standards for quality of fit, light weight, and durability in the toughest of climates. Aero Function offers a wide range of stylish products to customize your vehicles with add-on aero pieces such as front spoilers, lips, side skirts, roof wings, and trunk caps. They also offer light weight replacement bumpers, bumper covers, hoods, and trunk lid panels designed for the discriminating performance enthusiast that seeks increase performance while they add a high-dollar look to their vehicle.
