When oil mist from your engine breather hose sneaks into the air cleaner, it leaves a sticky film that can build up over time and make the intake area messy. A catch can stops that by collecting the oil before it gets there. The Aluminum 40-0568 Engine Breather Oil Catch Can is designed for that job, and at $44.99 it's a straightforward add-on for riders who want a cleaner intake. That can mean less grime, a cleaner air filter, and one less thing to worry about when you open up the bike.
Quick verdict
If you want a simple way to keep breather oil out of the air cleaner, this catch can gets the job done without overcomplicating things. It's a mechanical upgrade that does exactly what it's supposed to do, and the price is straightforward. It's not flashy, but it's functional. You don't need a high-tech setup to see the benefit.
Who it suits
This can is made for Harley, Indian, and BMW models, so if you ride one of those, it's a natural candidate. It's also a good fit for riders who want an easy installation-the included chrome mounting billet clamp means you don't need to source extra hardware. If you like doing your own maintenance, the simple design is easy to get your head around. If you ride in a variety of conditions, that simplicity helps.
Aluminum 40-0568 Engine Breather Oil Catch Can
The idea is simple: collect oil mist from the breather hose before it reaches the air cleaner. The body is finished in black, so it blends in on the bike. The top high-flow air filter acts as a baffle and can be cleaned, the bottom drain plug makes emptying easy, and a 90° barbed fitting connects to standard breather hoses. A chrome mounting billet clamp is included, and the unit comes with a 9-month manufacturer warranty. The main thing to keep in mind is that fitment is custom for Harley, Indian, and BMW models, so you'll want to confirm your bike's hose setup before ordering.
What stands out from the listed details
The cleanable high-flow air filter is the standout feature. Instead of replacing a filter element, you can clean it when it gets dirty, which is a nice way to keep running costs down. The 90° barbed fitting is also a thoughtful touch, because it connects directly to breather hoses without extra adapters. The black finish is subtle, so it won't draw attention if you prefer a stock look.
Meaningful trade-offs
This isn't a set-and-forget part. Like any catch can, it needs to be checked and emptied occasionally to do its job. Also, because it's designed for a range of models, it's worth making sure your particular bike's breather setup is compatible before you buy.
Bottom line
For $44.99, the Aluminum 40-0568 gives you a simple, mechanical solution for keeping oil mist out of the air cleaner. It comes with the essentials you need, and the design keeps upkeep straightforward. If you ride a Harley, Indian, or BMW, this is a reasonable option to consider. It's a small part that can help keep your bike running more neatly.
