My air filter looks a little "beaten" and want to replace it. However, I cannot find the correct size. Went on to AEM site and only found replacement filter w/ 2.75in. Can someone tell my the size of this air filter and where I can order a new one?

 

You can go to the K&N sight and they give you the exact dimensions of every filter they make. Just match it up or go bigger.

 

he can't go bigger or smaller, since the filters gotta fit the MAF adaptor plate.

most of the MAF adapter filters are 5 inches in opening, i think.
