Disclaimer:

Aero Function diffusers are aftermarket aerodynamic accessories designed specifically for off-road and show use. As with all Aero Function products, these diffusers are not intended for use on public roads, and Aero Function disclaims any responsibility for damage or injury resulting from their use. These diffusers are not ‘direct bolt-on’ parts and often require extensive preparation, such as sanding, fitting, or custom bodywork. Common issues with diffusers include potential warping, cracking, or fitment challenges, especially if they are not handled or installed properly.

Aero Function diffusers generally fit below the rear bumper, and in many cases, the bumper may need to be modified to accommodate the diffuser. It's important to note that many diffusers are designed to fit specific bumpers, certain trims, or aftermarket styles, so careful attention should be paid to the design and compatibility when selecting and installing a diffuser.

In terms of installation, Aero Function diffusers typically require separate mounting hardware, which is not included in the package. This hardware often includes L-brackets, bolts, screws, washers, and other fasteners. L-brackets are commonly used to attach the diffuser securely to the vehicle's chassis or bumper, while bolts and screws ensure a tight fit. In some cases, additional supports or reinforcements might be necessary, depending on the design and the specific fitment of the diffuser. Since this hardware is not included, installers will need to source the appropriate materials separately, ensuring they are compatible with both the diffuser and the vehicle.

For optimal results, Aero Function recommends professional installation by a custom shop experienced with aftermarket components. Traditional auto repair shops may lack the expertise to properly handle the nuances of fitment and hardware requirements.

Important Disclaimer:
Aero Function diffusers are designed strictly for off-road and show use. Due to strict Department of Transportation (DOT) regulations, most Aero Function diffusers are not street legal. Aero Function does not endorse or recommend using these diffusers on public roads or highways.

FAQ

Why does the hood require hood pins?

Aftermarket FRP and carbon fiber hoods require auxiliary hood pins because composite material expands, contracts, and flexes differently than OEM metal. Over time, this can shift latch alignment, and at highway speeds the reduced weight of a composite hood combined with aerodynamic lift creates upward force on the leading edge. Hood pins provide a mandatory secondary safety measure that eliminates the single point of failure.


Why Aerocatch? Aerocatch latches are the industry standard because they sit nearly flush with the hood surface — no protruding pin shafts. They use a spring-loaded, quarter-turn locking mechanism that clicks into a detented, closed position, giving both visual and tactile confirmation that the hood is secure. Unlike traditional hood pins, there is no separate R-clip or lanyard to lose, and the integrated assembly is available in finishes that blend cleanly into painted or carbon-fiber hoods. Originally proven in FIA-sanctioned racing series, they carry motorsport-grade reliability onto street-driven builds.


Hood pins are typically installed at the leading edge of the hood, approximately 6–8 inches inward from each headlight corner, with a solid backing plate on the underside. Never install through unsupported laminate. Professional paint and body shop installation is strongly recommended; mount all hardware before painting to ensure proper alignment and sealant application.

When reading the product description for one of the hood designs for an BMW F32, it says “Prep Work is Required” What do you mean by this?

Fiberglass parts always require prep work before they can be primed and painted. This product is made with fiberglass material; therefore, it will exhibit chips, breaks, cracks, waves, scratches and holes which require modification. It is necessary to dry fit and drill mounting holes and perform body work before painting. Cutting and adding fiberglass may be required for proper fitment. Ships direct from the manufacturer or a distributor. Primer finished. Hand layup is the manufacturing process used for the majority of our fiberglass parts. Hoods require hood pins. We do not offer any guarantee of fitment on vehicles that have been involved in accidents and/or have body damage or customization.
