So I decided to replace the performance air filter with a standard paper filter in an effort to solve my PSM/ABS lights coming on at 4.6k revs in 6th at full throttle (this is the only time it throws the codes)

I bought the filter from my local Porsche centre but I can't get the air box out to replace it, I found the main bolt holding the airbox in and the screws on the top and 1 on the side but I can't get the thing open or out.

Can anyone give me a clue please??

 

go to renntech.org and look it up

 

great advice, thanks, took me 10 minutes after reading their guide.
