    For a More Aggressive Engine Performance. Increase your truck’s fuel efficiency and engine performance with the new aFe Silver Bullet Throttle Body spacer. It has been specially designed to give your truck an improved combustion to increase its horsepower and torque.

    Improves Efficiency and Performance. The aFe Silver Bullet Throttle Body Spacer is one of the most effective ways to increase your truck’s fuel efficiency and performance. It’s installed between the engine’s throttle body and intake manifold. This increases the volume between the cylinder and throttle which significantly improves efficiency. It has also been designed to create turbulence inside the spacer for better combustion. The result is a significant boost in horsepower and torque.

    Durable Billet Aluminum. This throttle body spacer has been machined from industrial-grade T-6061 billet aluminum for long-lasting durability and performance. It comes with serrations at the spacer entrance to reduce whistling at idle and cruising speeds.

    Backed by Warranty. The Silver Bullet Throttle Body Spacer is covered with a limited 2-year warranty against defects in material and workmanship.

    Application. The aFe Silver Bullet Throttle Body Spacer is designed for use on the 2011-2016 Ford F-150 3.5L EcoBoost pickup trucks.

            Thrown away money

            This accessory is very hard to see or feel Gaines from. I have since removed his from my vehicle after realizing that it actually restricts air flow when placed between a BBK 73mm TB. The BBK and manifold inlet are spot in, but with the spacer in there, the path narrows significantly through the spacer. I’ll have to drive it more to see the difference in Performance. The other thing I noticed when I went in to clean my TB is that moisture and oil had accumulated in the grooves of the spacer.

            Nice little upgrade

            I'm not entirely sure it helps with anything, but if nothing else it makes under the hood look a little nicer.

            Cool product

            Super easy install, not too sure of the performance increase as i put a cold air intake in at the same time, but i do know that with both together my truck runs great.
