Does anyone have any pictures of the back side of the driver's side intake grill? It appears that the clips on the back are somewhat different than those of the 2002 and earlier cars. I had the 987 airbox installed when the engine was out but when I got some old parts back from the shop I see that they didn't install the snorkel on the 987 airbox and I would like to if possible. There is a lot of intake air noise over 4,000 rpm and if the snorkel will tone that down a bit I won't complain. Yesterday I tried to take the vent out but gave up due to the colder weather, as I didn't want to break it. I think it may come out when temperatures are a bit warmer and the plastic maybe a bit more flexible and I know where the clips are. I did do a search and only found these 2 threads with some relevant information.
