Fits:

• Focus MK2 ST & RS

Tuning levels on the Focus RS & ST have pushed the standard Ford oil filter housing to its limit, with the fragile diaphragm inside these housings splitting and also leaking due to the clip on design, a upgraded breather system was required, the AS Performance 2 piece breather kit ticks all the boxes and more...

The AS Performance 2 piece breather kit includes the following:

• 1 x Modified & Baffled Ford oil filter housing, includes new oil filter element and oil seals for no fuss fitting
• 1 x AS Performance oil separator with billet mounting block and laser cut fitting washer that also doubles up as a template when drilling to attach separator to battery tray
• 5 x Pro-Hose oil resistant Fluorosilicone lined hoses, custom made to fit your engine bay, far superior fitting than straight hoses and available in various colours to match your engine bay. Complete with full stainless steel chunky jubilee clips, very minor trimming of hoses may be required. 
• 1 x Mini breather and alloy joiner, this attaches to bottom of AS oil separator hose which runs down back of engine and secures to the gearbox with a modified stainless 'P' clip, its positioned so any engine fumes exit underneath the floor pan
