Performance Throttle Body Spacers are very effective accessories that are mounted in your vehicle’s air/fuel intake area. Carburetor vehicles had them first through permitting extra fuel/air mix for power enhancement. These were used to "disturb" air by the fuel’s formation of smaller droplets. On the other hand, the modern fuel injected vehicles utilized the spacers that allow greater amount of air within the throttle body assembly, subsequently allowing the engine to easily let the air in. Overwhelming loud hissing and whistling noise are so prevalent with most throttle body spacers today. This is the reason why experts have brought an innovative bore design that eliminates unwanted sound, while still causing incoming airflow to smooth out and speed up. By such design, you can let performance-enhancing air charge flow through the combustion chamber without even having all the annoying noise. The optimized mixture of air and fuel can attain gains in the mid-range power band while increasing the fuel economy. Throttle Body Spacers that also incorporate a patented helix bore are designed to spin the incoming air charge to increase velocity for improved atomization. This kind of design can possibly result to improved combustion efficiency that boosts low-end torque, throttle response, and fuel efficiency.
