Standard Ignition SK129 Fuel Injector Seal Kit

Fuel Injector Seal Kit for Toyota and Lexus

Standard Ignition SK129 is a fuel injector seal kit built for direct sealing at the injector-to-fuel-rail interface. It uses high-temperature Viton O-rings to maintain a secure seal in heat-heavy engine environments, with oil- and fuel-resistant construction for dependable service on Toyota and Lexus applications.

• High-temp Viton O-rings for sealing under extreme heat
• Oil- and fuel-resistant material to help resist premature breakdown
• Designed to match injector and fuel rail mating surfaces
• Seal type: MFI
• Assorted sizes for application-specific fitment
• Compatible with Lexus ES350, RX350, and RX450h applications

Detailed Description

Standard Ignition SK129 is engineered for fuel injector sealing service on a wide range of Toyota and Lexus vehicles, including Camry, Avalon, Highlander, Sienna, RAV4, ES350, RX350, and RX450h. The Viton-based O-rings are selected for high-heat environments and are built to resist exposure to fuel and oil during normal engine operation. This helps maintain the seal between the injector and fuel rail, which is critical for stable fuel delivery and leak prevention. This part cross-references 1G1366 and 2-12385 for the same application.

Common Issues This Part Can Address

• Fuel seepage at the injector-to-fuel-rail seal
• Hard starting caused by leaking injector seals
• Fuel odor from deteriorated injector O-rings
• Rough idle related to vacuum or fuel leakage at the injector
• Seal wear from heat, oil exposure, and fuel exposure

Installation Notes and Tips

Inspect the injector and fuel rail sealing surfaces before installation and replace any damaged components that could prevent a proper seal. Clean all mating surfaces thoroughly, and verify that the seal type matches the injector and rail design before reassembly. For Toyota Camry fuel injector seal kit service, Lexus RX350 injector O-ring replacement, or Toyota Avalon injector seal repair, confirm the application by year and engine configuration before installation.

Quality Assurance

Standard Ignition builds this seal kit with materials chosen for heat resistance and chemical resistance, and the components are quality-tested for durability during vehicle operation. SK129 is intended to provide consistent sealing performance for fuel injector service on supported Toyota and Lexus applications.
