Ultimate Intake Upgrade for 4.6L F150

The aFe Silver Bullet Throttle Body Spacer is a simple yet effective upgrade designed to improve the airflow dynamics of your 1997-2010 Ford F-150 4.6L engine. By lengthening the intake tract length and introducing a unique serrated and helix design, this spacer creates controlled turbulence in the air entering the combustion chamber. This turbulence promotes better atomization of fuel, leading to a more efficient burn, improved throttle response, and noticeable performance gains. Unlike traditional helix-only spacers that often produce an annoying whistle, the Silver Bullet’s design eliminates that unwanted noise while still delivering the airflow benefits. Once installed, drivers can expect sharper throttle response, smoother acceleration, and improved low-end torque, making everyday driving and towing feel more effortless. So, whether you're looking for a little extra punch on the highway or simply want a cost-effective way to optimize your truck’s performance, the aFe Silver Bullet Throttle Body Spacer delivers a smart and practical solution.

Precision-Engineered Aluminum Construction

Precision-machined from 6061-T6 billet aluminum, this spacer is built for strength and durability without adding unnecessary weight to your truck. The high-quality aluminum resists corrosion and withstands the harsh conditions of the engine bay, ensuring long-term reliability. Its direct-fit design makes installation quick and hassle-free, utilizing factory mounting locations for a secure and stable fit. No tuning, cutting, or modifications are required–just bolt it on and enjoy the benefits.
