I'm looking for the P/N's for both a K & N, and a UNI 2 stage Foam filters that fit the YFZ450 ESR intake. The intake is aprox a 3" O.D. I called ESR for the P/N's, but he played silly about knowing the P/N's. I got the impression he wanted the sale, and so wouldn't let on... Anyway... does anyone know what the the P/N's are?
