6-Piece Fuel Injector Set 0R-3418 — Complete Replacement for Caterpillar 3304 & 3306 Engines | CAT 215, 219, 225, 229, 235, E240 & E300 Excavators

The Caterpillar 3304 and 3306 are among the most proven and widely used diesel engines in the construction industry — powering generations of CAT excavators that have moved earth on job sites around the world. When injectors wear out on these workhorses, performance drops fast: hard starts, black smoke, sluggish digging response, and wasted fuel. This complete set of six brand-new fuel injectors restores precise fuel delivery across all cylinders, bringing your CAT excavator back to the dependable, full-power performance it was built for.
