Hi all, Yesterday I popped a Neuspeed P-flo intake on. Firstly, didn't think it would make that much difference to the feel of the car. It pulls much more evenly in the mid-range and freer above 4k and feels much more responsive. Two issues though ... the top of my filter is black because it is sucking in fibers from the sound proofing on the underside of the bonnet. Would this be an issue? I imagine over time it will block the topside of the filter ... Second, at about 6k rpm there is a metallic "beeeeep" noise, which sounds like the aluminium resonating with the airflow or something. Anyone else experienced this? Overall though, very happy with it so far.
