   AFE part # 46-33020 is a throttle body spacer that fits 2015-16 Mustang GT 5.0L.  It has a Serrated/Helix Combination design for optimum airflow by increasing turbulence into the combustion chamber.  In-house Dyno testing resulted in max gains up to +14 HP and +15 lbs. x ft. of torque  (vehicle tested with drop in filter aFe Pro 5R # 30-10255).  This turbulence increases the air pressure resulting in increased horsepower, torque and improved throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other helix only designs.  This Silver Bullet throttle body spacer is made from precision machined from 6061-T6 aluminum and uses all factory mounting locations. A gasket and longer bolts are included providing stability and a hassle-free installation. This part will not work with an aftermarket intake system.
