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.

Great product.

I love it! My mileage went up and it sounds meaner. Yes, it whistles, but I love everything about it. Mid-range torque is astonishing while towing my 10,000 pound gamer. Amazing work.

Seems to have improved low-end torque. I also notice more when cruising and I punch it to increase speed. I am thoroughly impressed with AIRAID: They overnighted this part after UPS reported that my part was missing/damaged en-route.

Makes a great combination with a cold air intake a must have, you can feel and hear the performance.

I have this on my 2010 R/T paired with Airaid CAI and (Brand Name) 87mm ported tb along with every other bolt-on, small cam and full exhaust. I can't say how much or if it helped but it definitely complimented its counterparts. It does help with throttle response, no whistling sound like I heard ppl mention and helped me put down some good numbers at the Dyno with 418.3rwhp and 495.1rwtq. Get this product if you have the CAI and tb to match or don't waste your time. It definitely gets the most out of your airflow.
