If you’re running an aftermarket air intake system on your fuel injected motor, there’s a good chance it’ll use a conical or cylindrical air filter element.

Though most air filter elements tend to last a pretty long time, they’ll eventually wear out. And that’s doubly true if you live in a place that’s dusty, sandy, or excessively dry or damp—basically any environment that can accelerate the degradation (or clogging) of an air filter.

So if you’re looking for a replacement air filter element for your air intake kit, the fine folks at Green Filter will show you all the key measurements you need to make to ensure you get the proper size for your specific system.
