Audi RS3 (2021-2025) 8Y 034 Motorsport - Billet Aluminium DSG Breather Catch Can Kit

A premium billet aluminium DSG catch can for Audi 8Y A3/S3/RS3—eliminates DSG fluid spray, restores engine bay cleanliness, simple bolt-on fitment.

Key Features

• Billet 6061-T6 Aluminium Construction: CNC-machined body with durable black anodized finish ensures strength and stealthy styling. 

• Stainless Steel Baffle Inside: Traps transmission fluid effectively, preventing messy oil splatter across the engine bay. 

• Direct Replacement: Swaps in for the OE plastic vent—uses stock mounting points, no drilling or cutting required. 

• Upgraded Hose & Fittings: 8 mm silicone breather hose replaces the plastic OE line; includes billet banjo, washers, and robust mounting brackets. 

• Maintains Ventilation: Proper breathing is retained while containing escapees of DSG fluid under high-heat or launch conditions. 

Detailed Description

The 034 Motorsport Billet Aluminium DSG Breather Catch Can Kit is engineered specifically for the Audi 8Y A3, S3, and RS3. The OE DSG breather is known for allowing fluid to escape—especially during high-temperature operation or aggressive driving—leading to unsightly stains and messy engine bays. This kit replaces the plastic vent with a rugged billet aluminium can that safely collects escaped fluid and drains it back into the transmission, keeping the bay clean and looking sharp.

With meticulous attention to fit and finish, the catch can uses factory mounting points and includes premium hardware for a seamless installation. Finished in stealthy black anodized billet and incorporating a stainless steel internal baffle, this is as much a functional upgrade as it is an aesthetic enhancement.
