I have a 2004 cayenne turbo and need a replacement passenger side airbox. I have seen some for the cayenne S and wondering if anyone knows if the cayenne S and turbo use the same airbox.

 

Well it sure looks like they are the same but it shows as two different part numbers too. You might be able to call and find out if they are the same.


This is the S filter (item #1)...http://www.autoatlanta.com/porsche-p...section=106-00

And the Turbo filter (item #1)... http://www.autoatlanta.com/porsche-p...section=106-05




Unless you have a line on a used or cheap S filter housing it's only $40 more for the Turbo filter housing. At least as shown on Autoatlanta's site anyways .

 

I'd be willing to sell mine if you're interested mbagge01.

 

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.

 

that's a good question, don't know that answer.

But, from an engineers point of view:
if the volume mass differs from expected calculations, the signals won't like it, there could potentially be a issue.

 

I would think that the overall volume of air read by the MAF's that goes into the intake should remain stable, as long as there are not any intake leaks. The only variation should be the air going into each turbo since it would be expected that higher volume would come from the side with the aftermarket intake. My question would be if that would make one turbo spin differently than the other and then make the two banks of the engine act differently, or is the system set up to compensate for changes on each bank?

 

I see what you're saying, exhaust spools the turbo up though, but when there is twin anything, equal is always the best answer.

Stick to EVOMS intakes or both stock intakes, IMO. IDK.

 

Yeah until you can get a matching set stick with what you have already. At least for piece of mind.

 

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

 

I other thing I wanted to ask is if there are any hidden vacuum lines under the intake manifold that could break from the heat

 

-No-

 

Does using durametric to erase fault codes under engine setting and also do the adaptation, reset all the learned ecu maps like when the battery is disconnected
