Ford Intake Manifold Gasket Set 4R3Z-9439-AA (Intake Manifold Gasket OEM) 2 pcs

High Sealing of the Intake System

The set of original Ford intake manifold gaskets 4R3Z-9439-AA (Genuine OEM) is designed to ensure perfect sealing of the air intake channels. These seals are installed between the intake manifold and the cylinder head, preventing air suction and vacuum leaks. Using original Ford components guarantees an exact match to the geometric parameters of the seating areas, which is critically important for stable engine operation at idle, correct formation of the fuel-air mixture, and prevention of errors in the engine management system (Check Engine).

Premium Materials and Durability

The gaskets are made of special green fluorocarbon rubber (Viton), which is exceptionally resistant to motor oil, gasoline vapors, and high temperatures. The profiled shape of the seal allows it to maintain elasticity and resilience for many years of operation, effectively compensating for thermal expansion of metal and plastic parts of the manifold. The material is not prone to "hardening" and cracking, which is often seen in budget counterparts, providing reliable protection against intake tract leaks.

Installation Recommendations and Compatibility

The set of two gaskets (2-pack) is the optimal solution when performing scheduled maintenance or repair of the intake system. Replacing the seals is mandatory each time the intake manifold is removed to prevent repeated leaks. The gaskets have special centering protrusions that facilitate the installation process and prevent part displacement during bolt tightening. These components are widely used in Modular V8 engines with 4.6 and 5.4-liter displacement, installed in legendary American SUVs, pickups, and sports coupes.
