Review on Airaid 200 617 PowerAid Throttle Spacer by Tylin Meyer

Product worked great when installed correctly. I would have given five stars without the installation instructions. Only disassembly and assembly, which is not difficult. This part can be installed backwards and the part I received was stamped TBC (throttle body side) on the wrong side of the spacer. I was just mechanically inclined and things didn't look right. So I called them and asked which way the cone should go. (to the motor) I complained about 2 pages of instructions and NONE on how to set the clearance direction. Serious? A simple diagram showing the direction of taper would suffice. You can discard the remaining two sides. How many people have installed this product incorrectly and thought the part was defective? Unforgivable.
