Those of you with cosmo racing cai’s off of ebay, did you all have to modifty the opening where the cold air extension goes. It says to use a dremel or something to grind away at it and enlarge the hole so it can fit better. I have mine sitting in there the way it is right now and havent done that. It still does the job but should I consider doing that so it can fit properly? I love this intake but thats the one thing thats bugging me. Plus can you all tell me where exactly to installl the bracket that comes with as well. TIA guys.
