Description

So, this is my first kick at this and being a bit of a BMW fan, and also being really happy with all of the other BMW related prints I found I thought I would try creating a dynamic air scoop for my 07 335xi. The scoop sits in front of the Rad and mounts under the front suction hood to help direct air up into the intake duct. Similar devices online suggest that dynamic air scoops can add a few horsepower, but that they also work very well with aftermarket cold air intakes. Installation is easy, as shown in the photos for the passenger side: -remove screws and plastic "rivets" from the front suction hood to release it from the front engine support (first pic). Be careful with the rivets as they can be brittle and may break, but they can usually be gently popped up with a flat screwdriver. -lift the front suction hood up and out (second pic) -insert (or wedge in) the dynamic air scoop at a bit of an angle. The scoop is only a couple of mm thick so it does flex. In this way you don't need to remove your kidney grills (third pic) -continue "wiggling", be sure to fit the plastic part of the front of the car between the two groves on the one side of the air scoop. This is what holds it in place on this side. (fourth pic) -get it all nice and flat and re-install front suction hood in a manner opposite to its removal. On mine, I had to trim a bit of plastic off of the front suction hood to get a nice fit, but very little, likely less than a millimeter. (fifth pic) -unit should "tuck" in nicely behind the kidney grill and in front of the rad (sixth pic) Driver side is the same process. I hope this is useful to someone and thanks again to all of those BMW ethusiasts would create and post so many useful things.
