Fuel Injection Plenum Gasket

DNJ Fuel Injection Plenum Gasket

DNJ® Fuel Injection Plenum Gaskets are designed to provide a secure, leak-free seal between the intake plenum and the lower intake manifold or throttle body. These gaskets are essential for maintaining proper air and fuel delivery, preventing vacuum leaks, and ensuring consistent engine performance. Each application-specific set may include the plenum gasket, throttle body gasket, and any necessary O-rings or seals required for a complete plenum installation. Engineered to match OE specifications, DNJ® Fuel Injection Plenum Gaskets ensure a precise fit and optimal sealing performance.

 DNJ® Fuel Injection Plenum Gaskets are manufactured using premium materials selected for their sealing integrity and thermal durability. Common materials include rubber-coated metal for flexibility and structural stability, molded silicone for superior temperature resistance and elasticity, and high-density fiber or graphite for sealing irregular surfaces. These materials are engineered to perform under high vacuum and fluctuating temperature conditions commonly found in modern fuel-injected engines. All components are produced to meet or exceed OEM quality standards for long-term reliability.

DNJ® also offers a wide range of related components to support complete intake and engine sealing service, including intake manifold gaskets, throttle body gaskets, cylinder head gaskets, full engine gasket sets, and more. With precision engineering and top-tier materials, DNJ® Fuel Injection Plenum Gaskets deliver exceptional performance and long-lasting durability.
