The bottom air duct on my intake failed. This is the tube that goes from air intake down side of motor into turbo housing (I think it goes there).

Car started getting error codes related to idle fluctuation and the car idles very low. When getting on the throttle it sounds like the blow off was happening while still on the gas.

Poked around and discovered the plastic flange that attaches this duct to block was sheared off and I could wedge my pinky into where the two ducts attach.

So, has anyone replaced? top portion looks easy. Not certain where the tube terminates. I assume into the turbo housing. Can I get to that from under the car once shrouds are removed?

It's part number 13-71-7-599-290 for reference.



I'm going to replace the diverter valve while I'm in there with GFB’s DV+ unit. Not sure if water pump needs to be drained and removed or not though..

Any advice is appreciated. Only owned the car a couple weeks so all still new to me.

That is the turbo inlet pipe. Both Pure and VRSF make this currently. I cannot comment on the VRSF pipe as I have the pure unit. I installed my DV+ while the turbo was out of the car so I do not know what may need to be removed to install it while the turbo is on the car.

N55 motor you can access the inlet pipe from above the engine bay. You do have to remove & drain the water pump (For DV+ Job). that piece is common for breaking after being under heat for soo long. I currently have VRSF inlet and cannot speak on Pure*. Good Luck bro

Replaced the inlet pipe with an OEM unit last night. Pretty straightforward job. That resolved the issue. I ordered GFB’s DV+ and will replace that when it's not so bloody hot outside.

Thanks to all for the input!

Anybody that is changing the inlet pipe obviously is after higher power. You must make it a point to also change that accordian looking coupler between the air box and inlet pipe as well. The coupler has a tendancy to collapse under higher boost, thus offsetting any potential gains from installing an aftermarket inlet pipe.

Good to know. Thanks. This is a Houston car with 70k on it. Everything plastic under the hood seems worn out. So far charge pipe, inlet pipe and plastic part of rail pressure sensor. None of it a big deal but frustrating in the short term.

You don't need to remove water pump to do dv+ def makes it easier but its possible without. Will need a tiny bit holder for under bottom side. Remove thermostat electrical connector for bottom bolt. Top two are easy with intake and tic piping out.

robertm Did you find a youtube video to help? I need to replace the same tube. Were you able to replace it from the top, or did you need to go under the car? Thanks.
