My truck is a 1998 F150 ext. cab long bed fully loaded. Everything on the truck is stock except for the new air intake. I recieved my airforce one air intake kit today from BTG Motoring company. The instructions were very well written and made it easy to install. It took me about one hour to completely install the whole kit and the moment I started it up I knew I had more power. I took it for a test drive and WOW! it will put you back in your seat fast. I havent timed it 0-60 yet but im sure it is going to be fast. I fully recomend BTG motoring company they have excellent customer service and seemed glad to help with any questions I had.
