I replaced my pollen filter with a Crosland Cabin Filter from Euro Car Parts (about 30 quid). The replacement was slightly too wide, but a simple straight cut from top to bottom, slightly narrower than the required width, followed by sliding the right cut folds into the left cut and it slid up into the pollen filter holder in the passenger foot well (UK version right hand drive) like a glove. Keep your old original filter as a width guide for future fittings. Cheaper versions can be found on the top auction website people shop on... Best wishes, HH
