AEM 21-200DK Universal DryFlow Clamp-On Air Filter: Round Tapered; 2.25 in (57 mm) Flange ID; 5.125 in (130 mm) Height; 6 in (152 mm) Base; 5.125 in (130 mm) Top

Great filter. I have used several of these and this version is my favorite. AEM has slightly changed the design over the years and this new version is great. They last basically forever if you clean them, I instead choose to just replace them every 30000 miles. I usually use a hydrophobic cover from a different company but this time got the AEM version. It fit great over the filter and for me is a required item to avoid getting some water in the intake. Never hydrolocked, I have a bypass, but enough to get the o2 sensor dirty.

Works as a filter should! Got rid of a poopy filter my greddy turbo kit came with on my s2000 and slipped this filter on. No issues and its good to know its filtering without sacrificing air flow.

Great product fits perfect

My first filter lasted for over 12 years, my mpg has improved, my car runs great again!

I was getting water in my intake after 60,000 miles because I changed the cold air intake filter on my 06 Scion xB to an aftermarket brand.. Big mistake. I bought this one now along with the sock that goes with it and whew no more water getting there during a light rainstorm..
