Cabin Microfilter Replacement (73094 miles)

Cabin microfilters arrived from Cotswold BMW. Fitting takes 5 mins. Just turn the locking latch through 90 degrees using a socket and remove the upper housing. Remove and replace filter in same orientation and refit. Repeat on the other side.  

Drivers side first. Note that filters are carbon impregnated hence the dirty appearance. New one is on top, old one below.

Passenger's side next.
