Does anyone know the part number for a K&N Cone filter with a 2 1/2" flange?

2nd page, scroll down to mounting flange (F) 2 1/4 and pick the right size

The biggest KN filter that will fit onto the Alero's 2 1/2" flange is RC-5040. I just installed one on my Alero - sounds good, looks good and it improved my milage.
