Alfa 159 2.2 JTS Intake Rubber Sleeve SPLIT Part 1

Intake Rubber Sleeve replacement after 11 years since new!
An essential fix as the sleeve or hose is after the MAF.
If it is not fix, there will be unmetered air going into the engine and that will cause FC to increase and loud induction sound(that's good...LOL) but not good for the engine as unfiltered air will enter from there.

If that hose is torn, will the car receive any fault code and what code are those?
Because i get often the error codes P1172 and P1175
and my consumption is also higher

Hi Nabil,
By right, you should not get any fault codes, but you may have power issues or lean burn as the tear would be after the MAF and the extra air wouldn't be accounted for by the MAF.
In any case, just change to a silicone hose if the original is not available. ID is 80mm to 70mm.
As for P1175, you might want to look at the cam variator solenoid at the spark plug area located near the cam sockets. There are 2 of them. One for intake the other for exhaust.
If they fail, the cam adjustment would not be working and power will be poor.

Can't get this intake sleeve anymore

Hi thank you for viewing,
Unfortunately it is out of stock, but you can get a 45 degree angle silicone hose with a ID of 80mm to 70mm. Cut to right length and replace. Also works, not the best solution but better than nothing.
