I installed my Stillen intake on my P11 yesterday. It souds great except it clanks into the battery bracket at times and the stock vacuum hose could be a little longer. The hose fits on the Stillen intake but it is a stretch. I set it up like they showed in the picture. I am wondering if any body has done this install and had similar concerns or questons. I moved the battery as far forward as posssible but it still clanks against it when I turn the car off. Thanks.
