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"
