Standard Ignition SK128 Fuel Injector Seal Kit

Fuel Injector Seal Kit for GDI Applications

Standard Ignition SK128 is a fuel injector seal kit built for direct injection service where reliable sealing matters. It uses high-temperature Viton O-rings and assorted seal sizes to help streamline installation on supported Ford and Lincoln applications.

Compatible with Ford Explorer, Fusion, Focus, Mustang, Taurus, and Edge, plus Lincoln MKC, MKZ, and MKT models listed below. The SK128 is designed for GDI fuel injector sealing at the rail pack interface, where heat and fuel exposure demand consistent fitment.

Key Features

• High-temp Viton O-rings for sealing in elevated engine bay temperatures
• Assorted seal sizes for easier service matching during injector repair
• GDI seal type for direct injection fuel injector applications
• Designed to match injector and fuel rail mating surfaces for proper fit
• Quality tested for durability during demanding vehicle operation
• Standard Ignition SK128 cross-references MAHLE GS33882 for the same application

Detailed Description

Standard Ignition SK128 is a fuel injector seal kit for GDI systems that require accurate sealing between the injector and fuel rail. The Viton O-rings are selected for high-temperature resistance, while the mixed seal sizes help reduce time spent sourcing individual components during injector service. This makes the SK128 a practical choice for Ford Explorer, Ford Fusion, Ford Focus, Ford Mustang, Ford Taurus, Ford Edge, Lincoln MKC, Lincoln MKZ, and Lincoln MKT rail pack fuel injector seal service.

The part number SK128 is used for applications where injector sealing integrity is critical to fuel system performance. If you are servicing a Ford Fusion fuel injector seal kit application or a Lincoln MKZ rail pack fuel injector seal kit application, this kit provides the sealing components needed for the listed fitments.

What It Helps Address

• Fuel seepage at the injector-to-rail sealing surface
• Hard starting caused by injector seal leakage
• Rough idle related to compromised injector sealing
• Fuel odor from worn or heat-damaged injector O-rings
• Service delays when matching multiple seal sizes by hand

Installation Notes and Tips

Verify the injector style and rail pack configuration against the vehicle listing before service. Clean the injector and rail mating surfaces thoroughly, and inspect the sealing grooves for wear or contamination before installing the new O-rings. Use care during assembly to avoid twisting or cutting the seals, and confirm proper seating after installation.
