The mountune Billet Oil Filler Cap has just been released for the Focus RS Mk3 which provides a complete replacement for the plastic OEM version, machined from billet 6061 aluminium and hard anodised in gloss black, for a long lasting, high-quality finish.
Finished with a laser etched ‘mountune’ logo, it’s the perfect addition to any mountune powered engine / engine bay.
All fitted – hefty lump probably weight of a golf ball. Needed a couple of attempts at turning as it’s metal on metal (with rubber seal) as opposed to plastic. Note the dipstick is only for RS MK3 and not compatible with ST.
