Wake Up Your Low-End Power

If you drive a 2001 to 2003 Ford with the 4.2L V6 and want a bit more punch off the line, the Airaid 400-516 Throttle Body Spacer is a simple, effective upgrade that makes a noticeable difference. Designed to improve torque from just 800 RPM up through the mid-range, this spacer uses Airaid’s patented Helix Bore technology to spin the incoming air as it enters the intake. That spinning motion helps increase air velocity and promotes better fuel atomization, leading to smoother combustion and stronger throttle response where you use it most—around town, merging onto the highway, or towing a light load.

Easy to Install, Built to Perform

This spacer is precision-engineered to bolt in between the throttle body and intake manifold with no need for tuning or complicated modifications. It’s a quick afternoon install that gives your truck a more responsive feel without sacrificing reliability or driveability. You'll notice improved part-throttle power and a bit more confidence when pulling away from a stoplight or climbing a hill. Whether you're driving your truck daily or using it for weekend projects, this spacer adds performance and efficiency in a package that’s easy to install and built to last. It’s a great way to get more out of your 4.2L V6 without digging deep into the engine.

Fits: 2001, 2002, 2003 Ford 4.2L
