Will this scrape on steep inclines or driveway aprons?

The L Sport diffuser extends minimally below the OEM bumper line. Check your driveway angle and approach clearance before installation. If you frequently encounter steep driveways, measure the factory bumper clearance at your home first—this diffuser sits roughly in that zone.

Does the diffuser include mounting hardware?

The diffuser assembly is included. Confirm mounting point locations on your OEM bumper before ordering fasteners, as hardware spec varies by installation method (bolt-on vs. adhesive-backed clips). Reference your vehicle's service manual for the correct fastener type and torque specifications.

Is this diffuser functional or purely cosmetic?

The L Sport diffuser is a styling piece that follows the OEM bumper contour. It adds visual depth and aggression to the rear end but does not generate downforce or alter aerodynamic behavior. It's designed for clean appearance rather than performance benefit.
