Just picked up an 2004 X5 4.4i looking to give it some roar
quite a few maintenance Item such:
- valve stem job
- 0 Sensors
- replaced Purge Valve
- updated 4.8 Cluster (white LED's, Black face plate, mileage correction) * tb installed

some upgrades to:
- ECS Angel eyes Xenon white bulbs
- 4.8 rear exhaust setup (Piping , Mufflers, and tips)
- Under carriage guard rail
- OEM 19" in staggered wheels with run flats
- Schmeidmann front tower strut Brace tb installed

Mods in progress :

- Dinan TB upgrade
- Dinanantronics Stage 3
- AFE Cold Air intake stage 2
- front and rear Aerodynamics bumper

I am now realizing that the N62 engine has a very limited option in terms of performance mods out there. Can anyone suggest something I might not have mentioned very new to the BMW world and aside from selling this and trying to find a clean 4.8 or Dinan Modded out X5.
Any help would be greatly appreciated.
