Throttle Body Gasket Ford 4R3Z-9E936-AA (Throttle Body Gasket OEM)

Throttle Body Gasket Ford 4R3Z-9E936-AA (Throttle Body Gasket OEM)

Ensuring the Sealing of the Intake Unit

The original Ford throttle body gasket with part number 4R3Z-9E936-AA (Genuine OEM) is a key element for maintaining the correct operation of the fuel injection system. This seal is installed between the throttle body and the intake manifold. Its main task is to ensure an absolute seal of the connection, completely eliminating the intake of unaccounted air. Violation of the integrity of this unit leads to unstable idle speed, power loss, increased fuel consumption, and the appearance of errors in the engine control unit related to the lean fuel-air mixture.

Premium Materials and Temperature Resistance

The product is made of a specialized high-temperature elastomer (fluoroelastomer) in brown color. This material was chosen by Ford engineers for its ability to maintain elasticity and sealing properties under conditions of constant vibrations and extreme temperature fluctuations in the engine compartment. The gasket has high chemical resistance to gasoline vapors, oil mist, and aggressive cleaning agents that may be used during throttle unit maintenance. The profiled ring shape with a specific bend precisely follows the contours of the flange, ensuring even distribution of clamping force when tightening the fasteners.

Replacement Regulation and Installation

The 4R3Z-9E936-AA seal is a disposable part that must be replaced each time the throttle body is removed for cleaning or repair. Over time, the rubber undergoes natural shrinkage, and reusing the old gasket does not guarantee a seal. Thanks to the precise geometric dimensions of the original part, installation is quick and without the need for additional sealants. Using Genuine OEM components is the only way to reliably restore the factory parameters of the intake system operation of Ford, Lincoln, and Mercury vehicles.
