Standard Ignition SK65 Fuel Injector Seal Kit

Fuel Injector Seal Kit for Nissan and INFINITI

Standard Ignition SK65 is a fuel injector seal kit for service work on select Nissan, INFINITI, and Mercury applications. It includes the O-rings needed to restore injector sealing at the fuel rail and intake side, helping maintain proper fuel delivery and reduce leaks on affected vehicles.

Key Features

• Fuel injector seal kit for one injector service point
• Black finish
• Includes 3 O-rings
• No hardware included
• No nozzle seal, pintle cap, or upper intake manifold gaskets included
• Standard Ignition SK65 cross-references 2-12316 and 800-9250 for the same application

Detailed Description

Standard Ignition SK65 is built for injector reseal service where worn or hardened seals can affect fuel system integrity. The kit is specified with three O-rings and precise seal dimensions, including a 22.352 mm inside diameter for one seal, a 10.16 mm inside diameter for another, and a 3.302 mm inside diameter for the third. This makes SK65 a direct service part for injector sealing on applications such as 1998-2004 Nissan Frontier, 2000-2004 Nissan Xterra, 1993-2002 Nissan Quest, 1990-2000 Nissan Pathfinder, 1997-2000 INFINITI QX4, and 1993-2002 Mercury Villager. Standard Ignition SK65 is also listed for 2000-2001 Nissan Altima, 1995-1997 Nissan Pickup, and 1990-1994 Nissan D21, including California emissions-equipped 1993-1994 Nissan D21 models.

What It Helps Address

• Fuel seepage around injector seals
• Hard starting caused by injector air or fuel leaks
• Rough idle from compromised injector sealing
• Fuel odor near the injector rail area
• Service replacement for aged O-rings during injector maintenance

Installation Notes and Tips

Inspect the injector body, rail, and intake sealing surfaces before installation. Clean all mating areas thoroughly and replace damaged injectors or worn sealing surfaces as needed. Lubricate the new O-rings with clean engine oil or approved fuel-system lubricant before assembly to reduce tearing during installation. Verify the injector and vehicle application before service, especially on Nissan D21 models with California emissions.

Quality Assurance

Standard Ignition SK65 is a service kit engineered to match the sealing requirements of the listed applications. Confirm fitment by year, make, model, and emissions configuration before installation.
