An injector seal in a car is a small but crucial component of the fuel injection system. It is designed to create a tight seal between the fuel injector and the engine's intake manifold. The seal is typically made of rubber or silicone material, which is resistant to fuel and heat. Its primary function is to prevent fuel leakage that can occur when the engine is running or during fuel system pressure testing.

By maintaining an effective seal, the injector seal ensures that fuel is delivered accurately and efficiently to the engine cylinders. A faulty or worn seal can lead to several issues. First, it can cause fuel leakage, resulting in fuel wastage and potential engine performance problems. Second, it can disrupt the proper air-fuel ratio in the cylinders, leading to rough idling, misfires, or reduced power output. Finally, a failed seal can also allow external contaminants, such as dirt or debris, to enter the intake manifold and cause further damage to the engine.
