Tackle direct-injection seal jobs the right way with the Oni Tools GM245 Injector Seal Installer & Sizer Set. This 4-piece kit installs and sizes the Teflon seals on SIDI injector tips so they slide into the cylinder head without snagging or leaking. It’s an alternative to EN-49245, EN-51105, and 18683AA000 and is designed for popular GM 2.0L/2.5L/3.6L/5.3L/6.2L and Subaru 2.0L/2.4L turbo applications. Two pilots guide seals into the correct grooves, the installer driver seats them, and the compression sizer brings the seal to the engineered diameter for a reliable, leak-free fit. Built from shop-grade steel for daily use, this kit is ideal for both professionals and advanced DIYers working on DI injector service, drivability complaints, or injector replacement. Use whenever injectors are removed to avoid seal damage and ensure proper tip geometry.
