airbox

[mbagge01]

I have a 2004 cayenne turbo and trying to find a new passenger side airbox. I have seen some for the cayenne S. Does anyone know if the airbox is the same for the turbo and cayenne S.

I'd suggest using board sponsor Sunset Porsche's online parts site ( http://www.sunsetporscheparts.com/ ) to check part numbers for both vehicles; if they are the same, the part is the same.

I am about to install the stock intakes to see if that helps but I just have the drivers side right now. If I install it and leave the evom intake on the passengers side, will the car drive fine or will it cause air fuel issues between the two banks.

Any differences in air flow should be adjusted and compensated for by the DME.

I have both air boxes and air ducts for 2004 S I will give you free. I am in Kingston Wa.

So I replaced the airboxes with the stock setup and still the surging problems that occur about 10 minutes after resetting the dme. I am suspicious for maybe a vacumn leak at one of the hoses on the back of the intake as they are the only ones I have not check. Is it possible that a vacuum leak may not manifest itself with problems driving after resetting the dme until the dme has a chance to start adjusting the seeing errors in air fuel ratio from O2 sensor

One other thing I was wondering is if there are any hidden vacuum lines under the intake manifold the could tear from heat

No vacuum hoses under the manifold that I can remember. Those crappy larger plastic vacuum pipes that Porsche uses can crack and leak almost un-noticed more so than the smaller lines. I'm sure you've checked most all of them but there are the ones running along the firewall, to the Vacuum pump as well as the ones running on top of the manifold up to the throttle body. Likely suspects that would cause an overboost are the ones that split and go to the compressor side of each Turbocharger and then on to the Boost valve mounted towards the back of the engine. A bad Boost (N75 in VAG speak) valve can cause issues. Software issue?

When I use durametric and hit the erase fault codes and reset the adaptation under the engine tab, does that perform the same thing as when I disconnect the battery to reset all the learned engine parameters

Yes.
