The filter Cobb supplies with their SF intake is just a touch to long for the air box and finding a filter with and internal diameter of 4.5 inches that is shorter than the filter that comes with the intake is almost impossible. AEM has one that is 5 inches long with a 4.5 inche diameter that most people use and crush it like my old filter was. K&N make the one Cobb supplies and it's just under 5 inches long and it gets crushed too. Finding this filter is like finding a unicorn sitting on a pile of gold and diamonds!

Bought this filter because my current KN wouldn't fit with my new FP intake and this one fits perfect clearing the ACD.

Replaced a no-name filter that came with my T1R carbon fiber intake. It is a little shorter which is nice because the original one used to hit the battery and was getting damaged because of it. This fits great and works great...now on the the other problems with the car. Great buy and a great price.
