Hey... I bought an AEM Brute Force a while ago with the oiled filter... now they have a new filter element that doesn't use oil and I'm thinking of getting one... the only problem is the size... they have two sizes a length of 5" or 9". Right now AEM gave me a 9" which I think is too large but I can't do the math for how much air needs to go into the 2.2l... What do you guys think... get a smaller filter or stay with the large 9-incher? Inlet will be the same 3"

Bigger is better imo.

either will work but air is going to be pulled through the path of least resistance, so when the 5" filter is dirty, your 9" will still have the equivalent 4" of clean filter. 9" would probably be cheaper long run.
