Ultimate Intake Upgrade for 5.4L F-Series Trucks

The aFe Silver Bullet Throttle Body Spacer is designed to improve airflow and enhance the overall performance for your 2004-2010 F150, F250, or F350 with the 5.4L engine. This simple yet effective upgrade helps improve throttle response and efficiency by altering the way air enters the intake manifold. By creating turbulence just before the air reaches the combustion chamber, the spacer promotes better atomization of fuel, leading to a more complete burn. The result is increased low-end torque, smoother acceleration, and a slight boost in overall horsepower–especially noticeable when towing, hauling, or merging onto the highway.

Serrated Design Reduces Unwanted Noise

What sets the Silver Bullet apart is its unique Serrated/Helix design. Unlike traditional helix-only spacers that often produce an annoying whistle, this combination design reduces unwanted noise while still improving airflow. The serrations help break up the air charge, preventing restrictions and promoting a more even distribution of air and fuel. This means your truck runs more efficiently, responding quicker to throttle inputs with a more immediate and predictable power delivery. What's more, the fitment is exact, ensuring a perfect seal between the throttle body and intake. Installation is straightforward, requiring only basic hand tools and utilizing factory mounting points for a hassle-free, bolt-on upgrade.
