Upgrade your R129 with precision-engineered ram air ducts that deliver both form and function. By directing fresh, high-velocity air into the intake path, these ducts help create a mild “ram air” effect at speed—building higher air pressure at the filters. The result is a denser air charge, improved throttle response, and greater efficiency.

Unlike the factory ducting, these performance ducts maximize airflow with smoother passages and a direct route to the intake. More oxygen means more power, and cooler intake temperatures support consistent performance run after run.

Built to integrate seamlessly with any R129, these ducts retain an OEM-plus look while offering a noticeable performance edge. Ideal for enthusiasts who want to get the most out of their Mercedes without compromising refinement.

The ducts can be installed on factory intakes and all duct orders include a discount code to use towards the future purchase of one of our intake systems! The ducts are automatically included with all intakes unless the discount code is applied.
