OSIAS 2.0L Oil Breather Aluminium Catch Can (2 x 12AN)

Really impressed with the quality of this OSIAS 2.0L oil catch can, especially for the price point. The aluminium construction is solid, welds are clean, and the overall finish feels well above what you’d expect for a universal setup.

The 2 x 12AN ports are ideal for high-flow applications, and the internal baffling does its job properly. After installation, blow-by control is noticeably better, and there’s been a clear reduction in oil vapour making its way back into the intake. The included breather filter is decent quality, and the drain at the base makes servicing simple without needing to remove the can.

Mounted easily in the engine bay and looks purposeful without being over the top. This is a well-thought-out, functional catch can that actually does what it’s supposed to do, not just a dress-up part.

Great option for performance builds, track cars, or anyone wanting proper crankcase ventilation without spending crazy money. Would happily use OSIAS again.
