Hey. I got my hotshot intake from CB performance up in Cali. I would in no way get anything directly from Hotshot. From th epast calls that I've made to them regarding the headers, they seem unknowledgeable and inpatient. Plus they might charge you more than a regular vendor would. I don't have th enumber for CB Performance but I remember it cost me around $90 bucks shipped. As far as the cone filter, you can use any regular 3" cone filter you can get your hands on. I'm sorry, I don't have a part number for you. I recently bought an APC cone filter frm carparts.com for very cheap. Hope this helps.
