Want to add some precious ponies to your 5.0 in less than an hour? If so, then aFe Power's new billet throttle bodies (BTB) fit the bill. These easy-to-install products will increase your Ford's power by a dyno-proven 17 hp and 15 lbs.-ft. of torque at 6,000 rpm! How did they accomplish this? The devil is in the details increase the bore diameter without going so big that installation requires a lot of fabrication; redesign from the ground up to improve the airflow path; use materials that protect against galling (chafing); use OEM electronics and gearing mechanisms to ensure proper function and connectivity, preventing rough-idling and tripping of the check engine light. It all adds up to make aFe billet throttle bodies one of the simpler bolt-on upgrades you can do to your car or truck!
