04-06 Ford F150 4.6L Throttle Body Spacer

The 04-06 Ford F150 4.6L Throttle Body Spacer from AIRAID INTAKE SYSTEMS is engineered for F150 owners seeking improved throttle response and air distribution to the intake manifold. This precision spacer inserts between your factory throttle body and intake plenum, creating a tuned plenum chamber that optimizes airflow dynamics during acceleration and cruise conditions. Built for the 5th-generation F150 with the 4.6L Triton V8 engine, it addresses the inherent lag in factory intake design while maintaining OEM compatibility and reliability.

AIRAID's design philosophy centers on velocity stacking and plenum resonance tuning—the spacer increases the distance between throttle body and intake valve seats, allowing air charge to accelerate and stabilize before meeting fuel mist. The compact 5.7 x 1.55 x 9.2 inch footprint weighs only 1.17 lbs, ensuring minimal added mass while maximizing airflow volume. The machined aluminum construction resists thermal degradation from engine heat, maintaining dimensional accuracy over thousands of heat cycles that occur during normal towing and highway driving in trucks.

This throttle body spacer is ideal for F150 enthusiasts running naturally aspirated 4.6L engines who want measurable mid-range torque improvement without forced induction or major engine work. Installation is straightforward—no drilling, cutting, or modifications to existing engine bay components are required. Compatible exclusively with 2004, 2005, and 2006 Ford F150 models equipped with the 4.6L Triton engine, this spacer pairs effectively with cold air intake systems and tuning modules for cumulative gains in responsiveness and fuel economy.
