I am looking for a K&N, Pipercross, ITG etc air filter. Preferably one that clamps onto some sort of tube with a max o/d of 100mm (preferably somewhere around 75mm). The filter itself needs to breathe plenty for a ZX12, and be no wider than around 120mm...

So, what have you got lurking under your workbench?!

I have a filter that's good for 250 bhp, which I've been meaning to upgrade since fitting the m3. Can let you have details when I'm back from hols next week.

That would be awesome. Enjoy your holiday!
