K&N Filter Failure and Replacement

[Slayer]

Further to my earlier post about cleaning a K&N filter, I took it off at the weekend to have a look at it. I noticed that the filter was missing most (more than half) of the cotton-like material that sits inside the plastic gauze part of the cone filter. This filter has not seen unusual use (such as a particularly dirty environment) and has only now just reached 30000 miles. On their website it says that the recommended service interval is 50000-100000 miles.

I was wondering if this is a common occurence, considering the 10 year/million mile warranty they have and also whether it is possible to buy just the cone filter separately as a replacement. There is no need for me to buy the whole kit as I already have the associated pipework and bracketry.

You can buy the cones seperately, but I'd complain about the service life and see if you can get one free.

Yeah id do that too.

Ok chaps, thanks for the input. I'll give complaining a go
