Hi all !!! Aero tuning package bumper spoilers installation on BMW X5 E70. that package can only be installed on LCI model 2010-2013. Front and rear bumper spoilers assembly. I am doing that video, just because there is no any instructions on the internet of how to assemble all the pieces...
Thinking of installing a tuning box to up the torque and bhp.
Has anyone got one of these boxes fitted? Like to get some feedback.
Tuningbox.com shows the performance figures as:
default: 177/350 HP/Nm
upgrade: 211/410 HP/Nm
