The AIRAID 300-573 fits some Dodge Ram 1500 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.

May 17, 2016 - Part 300-573
Satisfied with this product. It wasn't a throw your head back in the seat kind of difference but it was a considerable improvement. I purchased both the spacer and modular intake tube and together they have improved air flow. Much better throttle response and improved power in the low to mid range, didn't do a lot for the top end but it still improved. Fuel economy is yet to be determined but it seems to be staying more or less consistent with where it was.
