The AIRAID POWERAID throttle body spacer for 2004–2010 Ford F-150 5.4L and select F-250/2010 Raptor applications uses a patented Helix Bore to create spinning airflow that improves atomization and increases off-idle torque roughly from 800–3,000 rpm. The spacer installs as a true bolt-on with supplied hardware and common hand tools, requiring no permanent modifications.
