Servicing the car today. A previous owner has put a pipercross panel filter in and its breaking up. All the rubber round the edge is perishing. So I'm looking to replace it with another panel filter. Which one do I go for? K & N, BMC or green. They are all similarly priced and I have had good experiences with the K & N and BMC but never used a green one. I really don't like the pipercross ones any way, had quality issues with them in the past
