I got my intake on ebay, SRI. Got a K&N filter for it. over 3 years, never looked back. Love it. Most of the intakes will run you about 30 bucks shipped (far cry for what the were 3 years ago! $$$). Anyway, get theintake, then go to Auto Zone or Advance, whatever auto store in town, and get a K&N cone filter. Will work fine.
If you want name brand, I can get you set up with Street Unit for an AEM if interested. Let me know, and I will get you a quote. Free shipping to your door.
