Thanks for your help
The black induction pipes(intake system) should lead up to a shiny metal thing,that's the throttle body. You should only have to loosen up the intake tubing to get the throttle body out. Before you do that and take a couple hours I would suggest just smoke testing which takes only a couple of minutes, if there is a leak then you saved a bunch of time.

Ok Found the Throttle Body

Ok I found the throttle body, although it seems different from what you described and the pics I found on the forum. By boxster is the 2.7 with the electric accellorator actuator rather than the cable.

Get that K & N air filter out of the car. When I had one it cost me $240 for a new MAF.

First you need something that makes smoke but not fire.....I use a thick rope with a smoldering end. You can also use a cigarette or cigar if you can tolerate the smoke. With the engine running, move your smoking instrument near the various pipes and hoses in the intake system (throttle body, vac lines, air-oil seperator, etc.) and see if any of them start sucking up the emitted smoke. If so you've found your leak.

The MAF (mass airflow sensor) is mounted in the intake pipe near the air filter housing. It has an electrical connector and it measures the amount of air entering the engine so the proper amount of fuel can be measured. An over-oiled K&N filter will contaminate the sensor, ruining its readings.
