Volant 35853 High-Performance Air Scoop for Dodge Ram - Improved Airflow & Engine Performance for Off-Road & Towing

This fit my 2003 GMC Sierra, 5.3L. I bought this as a replacement for one I had years ago, that one fell out on the highway I guess. This model seems to be updated. You remove the single tow hook bolt from the bottom with a 18mm wrench and slide the scoop in behind the tow hook and replace the bolt thru the scoop into the tow hook. I don't remember the old model having this hole for the bolt. This is a good update so the scoop can't fall out. The tube fit well, there was only a gap of 1/2" or so between the scoop tube and the tube out of the bottom of the air box. So the 3" silicon sleeve easily sealed that up. I also purchased the pre filter (Volant 51906) as recommended to stop water infiltration.
