The AIRAID 400-619 fits some Ford Explorer, and Ford F150 models. See vehicle applications for details.
The POWERAID Throttle Body Spacer is designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm. The spacer utilizes it’s unique, patented Helix Bore design to spin the incoming air charge as it passes through the throttle body spacer. The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture as the air charge enters the combustion chamber. The end result is more part-throttle torque and improved mid-range power.

July 23, 2015 - Part 400-619
Easy install...on '97 4.3 v-6 boosted bhp and fuel mileage after installation and switch to non-ethanol fuel. Est. mileage before was 17 mpg and after is now over 21 mpg. Great product. Wish you had an application for a 2007 Ford Explorer V-8.
