It depends on whether or not you believe it will do any good, prevent any harm, or just add underhood bling. It will catch some oil vapor [and possibly blow by] and keep it out of your intake manifold. You may or may not care about this.
Vehicles have been sending oil vapors/blow-by into the intake for decades and decades. People have been selling attachments to prevent some presumed harm from this for about as long.
If there is heavy blow-by, unless the engine is designed for it like an old Jag 6 banger, there may actually be an engine problem that a catch can just masks.
Opinions differ. Facts are considerably more rare.
