  • Seal type: GDI
  • Standard Ignition SK203 service part

Product Details

Standard Ignition SK203 is used to restore the sealing interface at the fuel injector during direct injection service. It is listed for 2017-2022 Subaru Impreza, 2018-2022 Subaru Crosstrek, 2019-2022 Subaru Forester, 2020-2022 Subaru Legacy, 2020-2022 Subaru Outback, and 2022 Subaru BRZ. This part cross-references 16608JB000 and 274925 for the same application. When replacing injector seals on Subaru BRZ, Crosstrek, Forester, Impreza, Legacy, or Outback models, SK203 provides the correct GDI seal format for service work.

What It Helps Address

  • Fuel seepage around the injector seal area
  • Hard starting caused by injector sealing wear
  • Rough idle related to injector air leakage
  • Fuel odor from a compromised injector seal
  • Service replacement during direct injection maintenance

Installation Notes and Tips

Confirm injector style and engine application before installation. Clean the injector bore and sealing surfaces thoroughly, and inspect the injector and surrounding components for wear or contamination before reassembly. Use the correct service procedure for GDI injector sealing to avoid damaging the new seal or the injector body.
