Cosworth CAI: replacement filter

To make a long story short, I crushed the original Cosworth air filter and was having issues finding a filter that was the exact size to replace it with. I found an AEM Dry flow that matches it perfectly, besides it being a non-oil filter. The Cosworth one was more or less a K&N oil style filter.

AEM Part number 21-2110DK

Its also made in the USA

Nothing on K&Ns site? Because they have everything under the sun, especially if you have the old filter to measure.

That is if you want an oiled filter again.

They didn't have an "exact" match. They have some that are close, closest being a cylindrical non tapered one. I did a lot of searching to see what us VIP Cosworth guys were using as a replacement, but got nowhere. Even called FSwerks to see if they had an idea. Figured I'd help out with what I found. Not too sure about these non oiled ones though.... First time using them.
