Ok guys...I had to trim one I purchased from Lingenfelter meny years ago, it fits perfect. If you take your time and as said above trim a little, fit it, trim a little, fit it, until you get it just right you will be very happy with the results. The best way is to use the plastic air filter housing as your guide to cut it with a sharp knife-its very easy to cut. Install the new duct onto the horn then install the filter housing completly with screws (leave yourself 1/2" extra on the horn incase you cut it too short) trim it using the rounded edge of the plastic housing as your guide. If you don't want to use the housing as your guide then use the hose clamp (installed over the duct and filter housing)...after marking it with an ink pen. Using the housing as your guide will give you a perfect fit but the duct and hose clamp may be a little difficult to install onto the horn beacuse of the A/C pully. Take your time it will fit.

Using the plastic air-filter housing is what I recommend as the filter housing-horn is not a perfect match, every vehicle may be slightly different and you will find the cut end towards the filter housing will be cut on a slight angle to fit it properly.

Hope this helps.
