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.

Thats odd, I have a stillen intake on my p10 and the mounting bracket is quite sturdy - no clanking or shaking around. Maybe the p11 one attaches differently.

There is no noise for my intake hitting the batt either. Are the bolts from the mounting bracket lose or something? As for the wires, I just left my air temp sensor in the stock ram air tube thingie so I wouldnt have to strech the wire. Works just fine w/o any engine problems.

I pushed the intake a littles farther back and seem to have curbed the prob. Thanks for the response guys.
