Review on Airaid 200 550 PowerAid Throttle Spacer by Jose Haskin

To all the snake oil sellers who sell shakers and flip flops, I figured this was another useless piece of equipment. Wrong answer. A 454 big block isn't known for its fuel economy. But after installing this unit and letting in cold air, fuel economy increased by nearly 5mpg, and that was me, "Mr. LEAD FOOT," driving cross country with a 2,000+ pound RV on my back. My truck mileage was still in the 12-15mpg range, suggesting something is going on outside the continental divide. Good, aesthetically clean and approved by California CARB. Good job air raid protection!
