I think it about £17-20 but I bought one from my local motor factors for £12 - It's best to take the old one with you as I think there may be two different types - the system can run without it for a day or so unless you intend to travel through the Sahara. When I changed mine recently i couldn't believe the dirt and black carbon particulate it had collected. Also if you live near trees I suggest you change it once a year especially after the autumn.
