4.8 upgrades

  1. X5 E53 (1999 - 2006)
    Just bought an Imola Red 4.8is. Love the car, but want to make some upgrades and I am looking for suggestions. I am not looking to make any crazy changes to the car, I am thinking an intake, chip, and exhaust to start things off. Any suggestions of proven products would be greatly appreciated...
