Fuel Injector Clinic Low-Z DSM / Evo Injector Seal Kit SLK-125-6X4
Service compatible Fuel Injector Clinic low-impedance DSM and Mitsubishi Evo injectors with the correct replacement seals using the FIC SLK-125-6X4 Injector Seal Kit. Featuring a Viton lower seal, this kit is designed for specific FIC Low-Z injector families and flow ranges. Most importantly, SLK-125-6X4 is NOT the correct seal kit for injectors with a scribed part number ending in "K," so the injector markings must be checked before ordering.
Fuel Injector Clinic offers different DSM/Evo seal kits based on injector design and identification, making exact part-number verification critical. SLK-125-6X4 fits compatible FIC 125, 126, and 226 injectors from 550cc/min through 1150cc/min, along with FIC 225 and 126/226 BlueMax injectors from 1250cc/min through 1650cc/min. If the scribed number on your injector ends in "K," Fuel Injector Clinic specifies SLK-126X4-K instead.

Important K-Suffix Warning
Check the scribed number on your injector before ordering. If that number ends in "K," SLK-125-6X4 is NOT the correct seal kit. Fuel Injector Clinic specifies SLK-126X4-K for the applicable Low-Z DSM/Evo injectors with scribed part numbers ending in "K."
Do not choose a replacement seal kit based solely on the vehicle, injector flow rate, or appearance of the injector. Verify the injector family, flow size, and complete scribed identification before ordering. This is especially important with FIC DSM/Evo Low-Z injectors because the K-scribed versions require a different seal kit.

FAQs
How do I know whether SLK-125-6X4 is the correct seal kit for my FIC DSM/Evo injectors?
Verify the FIC injector family, flow size, and the complete number scribed on the injector. SLK-125-6X4 fits the specified Low-Z injector families and sizes only when the scribed injector number does not end in "K."
What seal kit do I need if my FIC injector number ends in "K"?
Do not use SLK-125-6X4. Fuel Injector Clinic specifies SLK-126X4-K for the applicable Low-Z DSM/Evo injectors with scribed part numbers ending in "K."
