2-Piece Fuel Injector Set 4W-7016 — Partial Replacement for Caterpillar 3208 V8 Engine | CAT 613C, 225D, 229 & 231D

The Caterpillar 3208 is a legendary V8 diesel engine that powered some of CAT’s most iconic equipment — from the 613C motor scraper and 225D excavator to the 229 and 231D. When diagnostics confirm two faulty injectors on your 3208, this pair of brand-new fuel injectors is the precise, cost-effective solution. Engineered to OEM specifications, each injector restores accurate fuel atomization and consistent combustion to the affected cylinders — recovering lost power, reducing black smoke, and improving fuel efficiency on this proven V8 powerplant.
