Anyone know what k&n model induction kit this is?

You don't want to end up using a filter that is too small, no idea on filter size differences.
If you buy a kit, it comes with the mounting bracket as well, which if you've bought a 1.6/1.8 kit it will be in the wrong place. Having the original inlet elbow will make your inlet tract longer as well which should help along with a filter that isn't too small and old and clogged.

If you want to retain the nice sound but don't want something restrictive, a universal aftermarket filter from a good brand would be acceptable if you can figure out how to mount it, or the specific K&N 57i for the gti-6 which do pop up for sale every now and then. I run one of these behind an alloy shield.

I do have a BMC CDA for sale but I'm not sure it'd meet your needs as it isn't particularly easy to mount it without moving something else/having the cold air feed from a foglight.

Thanks for the info!
Im wanting something cheap and easy enough to fit, with decent sound but not so much that it drowns over the exhaust note and also something which isnt restrictive, was thinking of the standard airbox with k&n filter in, or standard airbox with standard top end filter, or something like a pipercross induction kit etc
