Like ballbag says . Keep your eye out on ebay for a green , k+n , bmc etc... It doesn't have to be for a clio as long as the hole is 70mm for the elbow , even if its bigger you can buy reducers . I bought a brand new k+n cone filter off ebay for £20 delivered . It wasn't advertised as being for a clio but it fits perfectly inside my custom made enclosure .
