Once the original diffuser has been removed, the replacement S3-style diffuser should be positioned and checked for correct alignment before being secured using the appropriate mounting points and fixings.

The diffuser should be checked carefully around the exhaust outlets and surrounding bumper areas to ensure correct clearance and alignment before installation is completed.

All fixings should be securely fastened without overtightening or damaging the ABS plastic.

Professional installation is recommended if you are not experienced with exterior body and trim components.
