Ordered this filter to fit a Procharger P1SC as I had almost zero room and could not use the included plastic intake. When installing, the opening is a tiny bit larger than the Procharger fitting so you have to just push it onto the fitting and keep it there will tightening the clamp. Took me a couple times to realize that as it would tilt off if you didn't hold it in place. Zero issues otherwise. Great option for those that think they don't have enough room for anything besides a turbo guard.

Fits my D1SC on a 2v 04 mustang gt.The sides are a little short, may starve the procharger for air. Haven’t noticed any restriction in power though. So for so good
