if u have one make sure it doesn't rub on the low pressure AC line. I've had mine on for almost a year and this past weekend i heard a hissing sound coming from under the hood, and i thought where the line was crimped it was leaking to find out at the dealer yesterday that the filter was rubbing against the AC line and put a small hole in it and of course its not under warranty so no more AC unless i fix the line myself or just get rid of it all together.
