The 034Motorsport B7 Audi A4 2.0T FSI Catch Can Kit! This kit was designed to offer bolt-on installation and hassle-free use, with a fully-recirculating design and oil drain system to ensure that the can never have to be emptied.

Our catch can kit is engineered to eliminate the most problematic assembly of the factory PCV system and can be installed with all engine covers in place.

The vortex catch can design is used in aircraft and motorsport applications to remove oil and water vapor from the crankcase fumes. As crankcase fumes are forced out, they enter the catch can tangentially, with centrifugal force causing heavier oil and water vapor to fling outward and drain down the walls of the can. This is a much more effective way of separating oil and water vapor than most generic "catch cans".

This bolts between the stock oil pan and turbo oil drain line without any modification and allows separated oil to drain back to the oil pan so the can never have to be emptied. An NPT plug for the drain is also included if you do not wish to recirculate.

CNC-machined from billet aluminum, this piece replaces the OEM plastic valve cover breather plate and features large-diameter connections for the supplied silicone hoses.

This CNC-machined billet aluminum provision blocks off the intake manifold port going to the factory PCV system and features a port to reference manifold pressure for a boost gauge.

Large-diameter hoses ensure restriction-free crankcase ventilation and are made from high-quality silicone for extreme durability.

Note:

Vehicles running catch cans in below-freezing temperatures are advised to remove the catch can during winter months to avoid freeze-up issues. Race cars that need to run catch cans in freezing conditions should take extra steps to prevent freeze-up, such as an electric heater or regularly cleaning the system. Take care when routing the lines and avoid drooping, as that can allow oil/water to collect and freeze.
