Review on Spectre 9973 Intake Non CARB Compliant by Jamil Fog

I would really like to give a better rating. The instructions were confusing but I know my engine well enough to figure it out. The biggest problem I haven't solved yet is the filter not staying where it should. The intake side narrows, which exacerbates the problem. There are ribs at the end of the filter to help hold it in place, but the suction side is completely smooth. I tightened the large clamp as best I could without damaging it, but the filter still slips off. I emailed the company for help so I can update this review but I'm strongly inclined to bring it back now.
