OK.. once I install this Air Intake, I got to source my own air filter element? Right? Since the standard air element is to be replaced every 3rd oil change (3rd year) or 54K (which is utterly absurd) as per CBS, what is the schedule for the "Sport" air filter element replacement? The instruction's pdf says to disregard the "standard" air filter element and use the "Sport" element that came with the unit, which appears to be darker in color. Where can I get the "Sport" air filter element replacements? Or can I use aftermarket high performance dry elements? i.e. K&N?
