Detailed Product Overview

Standard Ignition SK135 is built for injector sealing service where worn or damaged O-rings can affect fuel system integrity.

It is a direct service part for 2011-2015 Kia Optima, 2012-2015 Kia Sorento, 2011-2014 Hyundai Sonata, and 2013 Hyundai Santa Fe Sport.

Common Problems This Part Can Address

  • Fuel odor around the injector area from deteriorated seals
  • Visible seepage at the injector-to-rail or injector-to-manifold interface
  • Hard starting or rough idle related to injector sealing loss
  • Vacuum leaks caused by damaged injector O-rings
  • Service replacement after injector removal on Hyundai Sonata, Kia Optima, Kia Sorento, or Hyundai Santa Fe Sport

Installation Notes and Tips

Inspect the injector body, rail, and manifold sealing surfaces before installation. Clean all mating areas thoroughly and replace any hardened or cut O-rings during service. Confirm the seal profile and size match the injector being serviced, since this kit uses assorted O-ring dimensions for MFI applications.

Quality Assurance
