About Project

If you are looking for a way to improve your car’s performance and fuel efficiency, you might want to consider installing a throttle body spacer. A throttle body spacer is a device that attaches to the throttle body and creates a vortex of air that mixes with the fuel before entering the combustion chamber. This improves the atomization of the fuel and allows for more complete combustion, resulting in more power and better mileage.

One of the best materials for making throttle body spacers is aluminum alloy, which is lightweight, durable and resistant to corrosion. Aluminum alloy can be shaped into various designs using CNC milling, a process that uses computer-controlled machines to cut and drill precise patterns on metal blocks. CNC milling ensures high accuracy and consistency in producing throttle body spacers that fit perfectly on your car’s engine.
