Took my green cotton filter out to replace it with a cone in box project im doing and found it like this

This is about 7months old so just a warning for you all, this could of got worse and started falling apart.

I've seen worse.

Pastyboy's Green one: http://www.briskoda....cotton-filters/

You could try a pipercross one? which again falls apart http://www.briskoda....s/#entry2643955

I've got a K&N panel one and not heard any complaints about them, plus it has has a 1 million mile guarantee.

Manometer or digital differential pressure gauge (relative cheaps on eBay).

I appreciate tuned cars wolf down far more air than standard.

Comparing air pressure from the front of the car to that post MAF would be interesting.

See Autospeed article(s) for further info.

Either is best done with a passenger to note the results.

I see someone is selling a rusty old brown green filter on ebay, keeps popping up every week

My 3 year plus old K and N was sold on recently with not a trace of rust on it.

Apart from a clean needed it was as new.
