I have a brand spanking new, still in the box, never been opened K&N air filter for an RX300. Part number 33-2145-1. This is the updated part number according to K&N. Never had a chance to install it and it looks like I will be selling the RX so I won't need this anymore.
First $30 plus shipping gets it. Better to email me rather than PM's. Inquire at email@example.com
