If you're someone who tracks your car often or if you're just fed up with having your intake manifold walnut blasted, an oil catch can is for you. 034Motorsport's Catch Can Kit is the most comprehensive PCV system solution for the 8V Audi A3 and MK7 GTI on the market.
An oil catch can is a helpful piece of hardware if you have a modern turbocharged or supercharged car. Direct-injected vehicles, especially Volkswagens, have been notorious for issues with carbon buildup. A catch can does exactly as the name implies, "catching" oil vapors before they are re-circulated back through the intake of the engine.
High-quality oil catch cans contain either a filter or a series of baffles on the inside. These filters and baffles help to contain the excess oil at the bottom of the can while the now-filtered air is recirculated back to the engine. This clean air keeps your car running more efficiently and keeps carbon buildup from forming in your intake manifold and on your intake valves.
In this Really Quick Product Review, Nate gets hands-on with the Catch Can Kit from 034Motorsport. Made entirely from machined billet aluminum, it's a serious piece of hardware that we can't recommend enough.
There aren't any downsides to installing this oil catch can on your car; even completely stock engines can benefit from the addition of one. The only potential annoyance is that you have to drain your catch can occasionally (every two to three oil changes). The 034Motorsport Catch Can Kit makes this simple with the addition of flexible lines, an oil-level dipstick, and an easy to access drain plug. The kit comes with all the parts you need for installation, and in just two or three hours you'll be good to go. You can stop worrying about carbon buildup in the future.
