You're welcome. This is a time consuming Mod. The hardest part I found was getting the last bolt out of the intake plenum. I took the Plenum completely out of the way, makes installing the 987 air box easy. I didn't have a hard time at all putting the 987 air box in place. Second hardest thing, making sure you cut the silicone hose to the proper length. Tip on cutting the silicone hose itself, take one of the clamps and tighten it down on the hose were you want to cut it, then just use a box knife cutting right at the clamp, makes a nice straight cut.

Thank you, kram and all the others who have contributed to this and other threads that deal with this topic. I have already purchased the 987 airbox, TB, and Y connector. However, I am confused when you talk about the MAF housing. I understand you must use the stock 986 housing and MAF sensor but don't understand when you say you put the 986 housing into the 987 housing so you can clip it on?? I am not getting a visual? also, somewhere in these threads there is discussion regarding a e49 5 series BMW MAF housing?? Can someone explain and add pics if possible? Also, has anyone done this mod without removing the Left intake manifold? Can the airbox be removed/installed by just lowering the engine?
