So, if you own an Audi 8Y A3, S3, or RS3, you know how crucial it is to keep everything running smoothly, especially when you're pushing your ride to the limit. That's where the 034Motorsport Billet Aluminum DSG Breather Catch Can comes into play. This isn't just another aftermarket part; it’s a game changer. The factory plastic vent? Yeah, it’s tiny and not up to the task. When the DSG gets hot—especially when you’re launching hard—it tends to spew fluid out through the breather hose. You end up with DSG fluid coating your engine bay, which is not only messy but can lead to bigger problems down the line.
What this catch can does is pretty straightforward: it replaces that flimsy OE vent with a robust, CNC-milled 6061-T6 billet aluminum unit. This means no more fluid splatter and a cleaner engine bay. The internal stainless steel baffle plate is a nice touch, ensuring that any escaping transmission oil is kept in check and funneled back into the system where it belongs. Plus, the black anodized finish gives it a stealthy look that really complements the aesthetics of your Audi.
Installation? Easy peasy. The catch can uses all the stock mounting points, so you won’t have to break out any power tools or do any cutting. Just swap out the OEM plastic vent hose for the new 8mm I.D. silicone vent hose, which retains the OE connector at the transmission. And those powder-coated mounting brackets? They not only look good but also resist corrosion, keeping your setup looking sharp for years to come.
Here’s what you’re getting in the package:
And if you're wondering about fitment, this kit is designed specifically for the Audi RS3 8Y 2.5 TFSI (2023+). So, if you want to keep your engine bay clean and your DSG functioning at its best, this catch can is definitely worth considering. Trust me, your car will thank you for it!
