jamesduff.com makes headers for them, you can get a Diablo chip from motorhaven.com, intakes and exhausts are available but you'll have to do some searching. Kustomz.com has intakes for 3.0's and 4.0's, the 4.0 is based off of the 2.9 so the intake may be interchangeable, not sure though. Stay away from Throttle body spacers and Tornado air inserts.
