Choosing the right rear diffusers for your Audi

Match the diffuser to the exact rear bumper and exhaust layout. Check outlet quantity, tip position, parking sensors and tow-hook access where applicable. Always review the compatibility notes on the individual product page because equipment can change within the same model year.

• Match the model, chassis or generation and production year.
• Check body style, factory trim and facelift status.
• Review installation notes, included parts and any exclusions.
• Contact us before ordering if any fitment detail is uncertain.
