I had bought the drop in Cold air Airaid intake about a year or 2 ago.
After my filter ripped at the flange, I went ahead and got a K&N air filter.
I did a little cleaning in my garage on Sunday and found my old Airaid filter.
I called airaid on Tue and they sent me our a Filter at no charge.
While I was talking with the gentlemen on the phone I had told him that I would like to purchase the Pre Filter which is a sleeve to keep the filter clean in extreme conditions.
He told me I did not need it.
Today the package comes (in 2 days) and there is both the Air filter and the Pre sleeve.

Airiad really goes out of there way and I didnt even have to send back my old ripped one.

Airaid, Big thumbs up on Customer Service.

In case no one knows what the pre filter it, here is a pic of it
