The AIRAID POWERAID throttle body spacer for 2004–2006 Ford F-150 4.6L uses a patented Helix Bore to spin incoming air through the spacer, raising velocity and improving atomization for stronger mid-range power between roughly 800–3,000 rpm. The kit includes mounting hardware and installs easily with common hand tools as a true bolt-on upgrade without cutting or drilling.
