Crankcase Breathers - Pipercross Competition

Crankcase Breathers

Available in two different designs, all Pipercross breather filters prevent contaminated oil vapour from re-entering the engine.

"To-atmosphere" breathers are available in either a rubber or alloy neck and attach to your engine's existing crankcase hose. These filters use a crushed aluminium filtration medium which is resistant to petrochemical corrosion.

C9024/C9025 To-atmosphere Crankcase Breathers

In-line sealed unit breathers incorporate a washable reticulated foam filter that can be fitted into your existing crankcase pipework. These filters are ideal for engines where the crankcase hose is normally vented back through the air intake.

C9023 In-line Crankcase Breather

"To-atmosphere" breather filters are available in anodised red, blue or polished alloy, inline filters are available in polished alloy only
