What Is The Difference Between Different Size Oil Catch Cans For Your Barra

If you own a Barra-powered Falcon, you already know these engines are tough — but like any high-performance motor, they benefit massively from proper crankcase ventilation. One of the best upgrades you can make is fitting an oil catch can.

Why Your Barra Needs an Oil Catch Can

The Barra engine produces a noticeable amount of blow-by, especially under boost or hard driving. That blow-by carries oil vapour, fuel residue, and moisture back into the intake through the PCV system.

Without a catch can, this leads to:

  • Oil build-up in the intake and intercooler

  • Carbon deposits on intake valves

  • Reduced octane effectiveness

  • Inconsistent performance over time

A quality oil catch can captures these contaminants before they re-enter the engine, keeping your intake clean and your Barra running at its best.

What is the difference between our 3 oil catch can kits?

The answer is simple:
The oil catch can itself is the same high-quality unit — the difference between our 3 kits is the fitting size supplied.

We offer three oil catch can kits, each designed for a different Barra setup:

  • 10mm fitting kit

  • -AN8 fitting kit

  • -AN10 fitting kit

Each kit is tailored to suit different power levels and engine modifications.

What’s the Same Across All 3 Kits?

No matter which kit you choose, you get:

  • Same oil catch can body

  • Internal baffling for effective oil separation
