Keep Your BMW Breathing Easy—Catch Can 101 If you’re serious about performance, you know that power is nothing without reliability. That’s why we always recommend a catch can to keep your BMW’s engine running clean, strong, and carbon-free. Here’s the deal—your engine isn’t perfect. Every time you drive, oil vapor and contaminants escape from the crankcase and get sucked back into the intake. Over time, that gunk builds up on your intake valves, choking airflow, killing performance, and in some cases, causing misfires.
