Yup , Mark is correct. Depending on your bombing a relatively inexpensive fix is drill a 4 inch hole in the bottom of the filter box and get a dryer vent and remove the cover and flapper. Side the tube through the cut hole, silicon seal it or use sheet metal screws to attach to air box, trim the sheet metal tube, then install some flexible dryer hose down between the bumper and the plastic inner fender, zip tie into place. You can put screen or some prefilter sleeve over the end of the hose if you wish. This will give you cool relatively clean air from behind the front bumper. If you want to buy a kit check out this web site www.psmbuick.com and they can supply a kit. Next step you can change to a foam filter from this website www.trueflow.com and you should be good for around 350+hp for less than $100 with the hardware store dryer vent mod. Good luck!
