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.

Product Reviews

June 24, 2016 - Part 310-510
Ok, my son bought this thing for his 2000 WJ which I helped him to install. I suppose I shouldn't call it a thing as this is an excellantly engineered part which I know as a fact has improved power gains. Our issue began the first time we had a smog check since installing it. In short, it wouldn't pass the visual inspection even though it had the California emissions apporval sicker attached. As it seems the wounderful state of California failed to add the 1999 thru 2004 WJ with 4.0L to its approval list even though all XJ, which have the exact same motor, have been approved. I just got off the phone with AIRAID who were not aware of this, but assured me that this part has California emissions approval and a short visit to a state emissions referee would clear this up. I'll close with this an oustanding 50 state legal proven performance part with excellant service.
