As combustion occurs in any engine a certain amount of the pressure makes it past the piston ring and into the crankcase of the engine. This is called "blow by"

To prevent the crankcase pressurising from the blow by a Positive Crankcase Ventilation (PCV) system is used to allow this pressure to be relieved.

The factory system traditionally vents back into the intake behind the air filters. this air is a mix of vapourised oil and fuel.

As this vapour travels into the intake it forms carbon buildup,  mostly in the intake ports and valves, particularly on Direct Injected (DI) engines, that have no fuel mix in the ports behind the valves to clean the carbon off. 

Factory systems prioritise convenience and cost over the potential performance loss and engine life compromise that a catch can system would prevent. A catch can system is costly to manufacture and needs to be maintained (emptied and cleaned). So it is easier and cheaper to vent straight back into the intake. 

The ZAC Motorsport C63 catch can system features 2 billet aluminium catch cans. These catch cans are baffled, feature a drain bung, and a level indicator stick to check the oil level.

Atop the catch can is a small washable filter that allows the air to vent to atmosphere.

The ZAC Motorsport C63 catch can system features billet anodized aluminium fittings that mount to the existing factory components. The system is completely plug and play, and easily removed if ever required. The only permanent modification is drilling 2 small holes on one side of the radiator support structure. These holes will not look out of place since there are 2 holes already the same on the other side of the support structure.

 This is a limited pre order special.

This Pre Order will close on the 15th April 2022.

ETA for the first batch of ZAC Motorsport C63 Catch Can systems is 15th May 2022.
