The only aftermarket oil filters I know of are Bike Master, HiFlo and K&N. And no one makes the extended transmission filter for the SE5 anymore. K&N did, but they discontinued manufacture of that filter earlier this year. The only vehicle on the planet that uses that filter is the SE5 Spyder. Just not enough volume to bother with.
