Our team has been developing a dedicated 034Motorsport Catch Can Kit for the B7 Audi A4 2.0T FSI, built for easy installation and smooth long-term use. The system features a fully recirculating layout with an integrated oil-return solution, meaning you’ll never need to empty the can manually. It also replaces the most failure-prone section of the factory PCV system, all while allowing the original engine covers to remain in place (minor trimming required).
Key Features
• 034Motorsport Vortex Catch Can
Designed with the same principles used in high-performance motorsport and aviation, the vortex system forces crankcase vapors into the can at an angle. Centrifugal force separates heavier oil and moisture, directing them to the walls of the can where they drain away efficiently—far more effective than traditional, basic catch can designs.
• Oil Drain Adapter Kit
Installed between the factory oil pan and the turbo oil drain line, this adapter allows the separated oil to return directly to the pan. No emptying required. An NPT plug is included if you prefer not to run the recirculating setup.
• CNC-Machined Valve Cover Breather Plate
This billet aluminum replacement for the OEM plastic breather plate features enlarged ports to match the included silicone hoses, improving flow and durability.
• Intake Manifold Plug with Boost Tap
A precision-machined aluminum plug that seals the manifold port from the stock PCV system, while providing a built-in tap for referencing boost pressure—ideal for a boost gauge or related accessories.
