Standard Ignition SK127 Fuel Injector Seal Kit

Fuel Injector Seal Kit for OE-Style Sealing

Standard Ignition SK127 is a fuel injector seal kit built for direct sealing service at the injector-to-fuel rail interface. It uses high-temperature Viton material for heat resistance, along with oil- and fuel-resistant construction to help maintain a secure seal during demanding engine operation. This kit is a practical choice for Chrysler, Dodge, Jeep, Ram, Cadillac, Chevrolet, and Pontiac applications that require reliable injector O-ring service.

Key Features

• Fuel injector seal kit for MFI applications
• High-temp Viton O-rings for sealing in elevated heat conditions
• Oil- and fuel-resistant material helps resist premature breakdown
• Designed to match injector and fuel rail mating surfaces for proper fit
• Black rubber construction with a clean OE-style appearance
• Compatible with select Chrysler 300, Dodge Charger, Jeep Grand Cherokee, and Ram 1500 applications
• Standard Ignition SK127 is cross-referenced with MAHLE GS33682 for the same application

Detailed Description

Standard Ignition SK127 is engineered for fuel injector sealing service where the injector O-rings must maintain a tight seal under heat, fuel exposure, and engine vibration. The seal material is formulated for resistance to oil and fuel, while the Viton construction supports durability in high-temperature environments. The kit is designed around the mating surfaces of the injector and fuel rail to promote proper sealing and fit during service work. This makes SK127 a relevant replacement for vehicles such as the 2011-2019 Chrysler 300, 2011-2019 Dodge Charger, 2011-2019 Jeep Grand Cherokee, and 2013-2018 Ram 1500. Standard Ignition SK127 also serves other listed Chrysler, Dodge, Jeep, Ram, Cadillac, Chevrolet, and Pontiac applications where an MFI fuel injector seal kit is specified.

Common Problems This Part Can Help Address

• Fuel odor around the injector area caused by worn injector O-rings
• Hard starting or rough idle related to injector seal leakage
• Fuel seepage at the injector-to-rail connection
• Vacuum leaks from deteriorated injector seals
• Heat-related cracking or hardening of old injector O-rings

Installation Notes and Tips

Inspect the injector and fuel rail sealing surfaces before installation and clean away any residue that could affect the seal. Replace damaged or flattened O-rings rather than reusing them. Lightly lubricating the seals with clean engine oil or an approved lubricant can help during assembly and reduce the chance of pinching. Verify the application by year, make, and model before service; SK127 is listed for vehicles including 2011-2019 Chrysler 300, 2011-2019 Dodge Charger, and 2012-2019 Jeep Wrangler.
