Hi guys
does anyone know where I can find a good write up for how to change a 997.1 GT3 engine air filter?
thanks

its pretty straightforward; all you have to do is *loosen* the airbox from its mounting and then removed the cover (as I recall there are 8 screws
holding it in place - 4x top and 4x bottom) pull it off, replace filter, replace cover, tighten airbox (BMC filter recommended).

Its been a while since I did this on either my .1 or .2 ... so I cant recall if you
have to disconnect the airbox completely from the throttle body or not ...

its tricky to get at the screws at the bottom edge of the airbox, but it can
be done with the correct tools ... hence loosening the box from it mounts allows you to partially "pull" the box up/out to make access to the lower screws easier ...

if you want totally stress free then you need to disconnect the airbox from the throttle body and remove the box ...


I'll try and take a photo of my engine bay to direct you... if that would help?

Per Larry, I've found this is the quickest way:

agreed, its not impossible, but its (really) tough to get at the 4x captive screws on the bottom edge of the airbox lid in order to remove the cover...

as I recall all you need to do is loosen one of the locking bands (and possibly disconnect the cable to the sensor) to remove.

Pull of the elctrical connector from the MAF, and then loosen the clamp securing the airbox to the intake.



Then just tilt the airbox slightly backwards to clear the intake and pull straight up. Airbox is out.



Release all the screws around the airbox:



Split airbox:



Put new airfilter in, make sure its flush:



Put the halves back togheter, tighten all screws. Observe the two tabs that og into the rubber mountings in the car, and the hole that locks onto the small tab in the car as well.



Here is the two rubber mountings in the car, and the tab that the airbox is locked down to.

Airbox hole mounted on the locking tab - it just slides down and the rubber is holding it in place.



Thighten the band from step one, and install the electrical connector to the MAF sensor.
