Will this diffuser scrape on steep driveways or ramps?

The AF-2 profile extends modestly below the factory bumper line. Check ground clearance on your specific driveway angle before installation—if you frequently bottom out, measure the diffuser extension against your current suspension height and driveway grade to confirm fitment.

Is this diffuser functional or cosmetic?

The AF-2 features functional diffuser flaps that manage rear airflow and contribute to aerodynamic balance. You'll see real effect at sustained highway speeds; results vary depending on your suspension setup and driving conditions.

What prep work is needed before installation?

Clean and dry the bumper mounting surface thoroughly. Sand and prep the contact area to ensure solid fitment. Inspect the diffuser for any finish imperfections before mounting, and reference your vehicle's service manual for fastener specifications and torque values.
