The 3-piece self adhesive EFI Intake Gasket Kit for Mercury (Front Injected, Laser, XRI Style) 2.4 / 2.5 Liter engines, OEM part number 167371, serves several key functions:
 
Sealing: It provides a seal between the intake manifold and the engine head. This seal prevents air, fuel, and combustion gases from leaking at the connection point, ensuring that the air-fuel mixture is delivered properly to the cylinders.
 
Insulation: The gasket also acts as a thermal insulator, helping to reduce the transfer of heat from the engine to the intake manifold. This can improve the efficiency of the air-fuel mixture by keeping the intake air cooler.Vibration
 
Dampening: It helps to dampen vibrations between the intake manifold and the engine block, which can reduce wear and tear on the engine components.Fluid
 
Passage Control: In some designs, the gasket also aids in the correct routing of coolant or other fluids through passages in the intake manifold and engine block.
 
Overall, the EFI Intake Gasket is crucial for the proper operation and efficiency of the engine, ensuring a good seal and preventing leaks that could affect performance and emissions.
