Hi all,
Being my first I would like to say I am enjoying browsing through this forum as the X5 scene down under is not as widely recognized as it is in the US.
As my first post i would like to share my first 'performance mod' on my 2012 X5 35i. Some of you may know the LCI diesel X5s sold in Australia had a dual intake. I was able to obtain an OEM LCI diesel intake and attach it to the air-box of my 35i with a 23 degree, 220mm long, and 100mm diameter silicon hose.
Did it increase power? all i can say is the car is more eager in the mid-range i.e. the slight hesitation that occurred between 2.5krpm and 4krpm is now less evident however it has not disappeared entirely.
Now the best part THE NOISE from the N55:
The bark from the exhaust is louder on startup.
The induction sound in the mid-range in 2nd and 3rd gear is more enjoyable to listen i.e. louder
Finally the increased exhaust noise as the needle swings past 3krpm together with the exhaust flap opening is my fav.
I will upload some photos of this setup around mid next week when i fly home from work.
