Throttle Body Spacer
A throttle body spacer is added to a throttle body of an engine to improve a vehicle's fuel efficiency and to increase its power. If you want to know how this component works, you need to understand how a throttle body works first. Basically, the throttle body is located between the air filter and intake manifold and it functions by regulating and controlling air flow in the engine. It is also connected through the accelerator via a cable that opens the throttle's linkages to open the throttle plate and increase air flow. As a response to the increased air flow, the engine control unit orders the fuel injectors to release more fuel to maintain the correct air-fuel ratio in your system. When everything is in order, the engine's power is increased in the process. Throttle body spacers are added to provide a larger capacity for air intake every time the accelerator is pressed. So every time the valve of the throttle body is opened, a greater amount of air will pass through it and this will increase the power of your engine. Now that you know how a throttle body spacer works, here's a brief and general guide on how to install one in your ride.
Step 1: Before you can install a spacer, you need to remove the throttle body first. Begin by removing any engine shrouds that block your access to the throttle body. These are usually secured in place by bolts or clamps so make sure you have the right set of tools.
Step 2: Next, take the vacuum hoses and electrical connections out of the air intake tube and then disconnect the intake tube from the air filter box and throttle body.
Step 3: At this point, you should remove any other engine accessories that will hinder you from removing the throttle. When everything's out, remove the bolts that fasten the throttle body to the intake plenum.
Step 4: Once the bolts are gone, hold the throttle body using both hands and pull it out. Then, use a rag and some brake parts cleaner to wipe the throttle body and intake clean.
Step 5: Next, put the throttle body spacer between the intake plenum, throttle body, and gaskets. Make sure that the bolt holes on the gasket are perfectly aligned with their corresponding holes on the intake and throttle body.
Step 6: After that, secure the components by inserting and hand-tightening their mounting bolts in place. Always check if the gaskets are properly aligned and do the necessary adjustments as needed.
Step 7: When the bolts are all in, tighten them evenly by securing the bolts on the opposite side of the throttle body.
Step 8: When the bolts of the throttle body spacer are secure, you can reinstall the engine accessories that you took out earlier, including the vacuum hoses and electrical plugs. However, you could also replace them if you wish to do so.
Step 9: Then, reconnect the wires and tubes that you disconnected earlier, including the air intake tube, air filter box, vacuum lines, and electrical plugs. See to it that the air intake tube doesn't stick to moving or hot parts to prevent it from getting damaged.
Step 10: Take your ride out for a spin and observe it closely to find out if your new throttle body spacer works.
