Review on Spectre Performance Aluminum Intake Mounting by Joseph Morris

Perfect fit for my application. I used it to add a cold air intake through the fender on my Porsche 928. Actually bought 2 and cut off part of the flange from one of them so it doesn't protrude too far into the wheel arch. I mounted their smooth plate on top of the smooth plate and sandwiched a piece of hydrophobic K&N pre-filter material that I cut from the filter film I used earlier. The purpose was to prevent critters and possibly a small amount of water from entering the 4" intake and airbox. The measurements were accurate and the flange I left intact attached easily to the 4" silicone intake pipe I was using and since it was aluminum it was easy enough to cut with my band saw.
