Is it easy to install a catch can?

SECURE THE CAN The easiest, and let’s be honest, most satisfying part of the install is securing the new catch can to the engine bay mounting bracket.

The answer is yes. While a catch can won’t stop every last particle of contaminant from entering the intake manifold and coating the valves in a direct-injection engine, the less unwanted buildup the better. So, yes, a catch can isn’t a bad idea. At a minimum, it’s not a scam.
