I'm really impressed with how good mine has come up - just like new!

The filter really is a top mod! Will be cleaning mine every 5k miles now... Must remember to put the OEM one back in at 39000 though...

Hmmm - am I the only one curious as to why the Green gets so filthy so quickly compared to say K&N and the OEM filter? Is it just because its so much more effective at filtering? :confused:

I put the OEM one back in while the Green dries out' date=' and so much more responsive! Man it was filthy... Looking forward to putting it back in now - Behold 4500rpm again! [/quote']

I'd be interested if you notice any difference when you put it back in clean?

The K&N site has more info on the theory behind the air filters, but I can't find any direct air flow comparisons to see if the Green is any better when clean and dirty. :confused:

I guess the cupra intakes are speeding up the dirt intake a bit, oh well...proof they work better!

We are having some ITG filters made currently, we have used ITG in the past and they can hold a massive amount of dirt and still maintain very high flow.
