I'm returning my car to standard spec and have obtained an airbox and two pipes which I've fitted and it works fine. However there appears to be something missing from my car- there is nothing to bolt the airbox to! I have the two bolts that go front and rear of the box but there is nothing to attach it to. The box is supported in the middle and that's it. Anyone have any idea what should be there and better yet what the part number might be?
