4-Piece Fuel Pencil Injector Set 20671 — Complete Replacement for Case IH G188D & G207D Engines | 450, 450B, 455B, 480C, 580C, 586C, 1150, 1255, 1845 & 1845S

Give your classic Case IH equipment a complete pencil injector refresh with this full set of four brand-new fuel pencil injectors. The G188D and G207D engines powering the Case IH 450, 480C, 580C, 1150, 1255, 1845, and related models are proven workhorses — but worn pencil injectors quickly rob them of power, fuel efficiency, and reliable starting. Pencil injectors are a unique design that demands an exact match for proper spray pattern and injection pressure, and finding quality new replacements for these classic Case IH engines can be a real challenge. This matched set of four restores precise fuel atomization and consistent combustion across all cylinders, bringing your Case IH equipment back to the dependable, productive performance it was built for.
