BMW 3-Series Throttle Bodies

A throttle body is a crucial part of the air intake system in modern automobiles. Its job is controlling the amount of the air that comes into the engine. This amount depends on how strong you press the accelerator pedal. The component called the throttle position sensor determines a current position of the throttle and sends this information to the auto’s control module. The module, in turn, collects real-time data from some other sensors like the oxygen sensor and MAF, correlates total information, and gives respective commands to the fuel injection system regarding the volume of fuel that has to be injected into the engine. If the whole process in your BMW 3-Series is properly regulated, the balance of air and fuel will be adequate for optimum engine performance.

There are, however, a number of factors that can interfere with the smooth operation of a throttle body and lead to the issues with engine performance. These factors include dirt and other particles that can accumulate inside the housing, various damages, and electrical problems. Sometimes, issues can be fixed by flushing the throttle body with special liquids, but there are some cases when the replacement is necessary. If they occur, visit our store carrying aftermarket BMW 3-Series throttle bodies.
