If you own a Cummins K38 KTA38 GTA38 CM580 QSK, you'll want this Air Intake Manifold. Part number 3393154.it even replaces 3897779, 3866840, 3866023 if you need it to. It's tough, fits like a glove, and installs in no time. I've used these before they last forever and keep the engine running smooth. Great for trucks, construction equipment, or generators any heavy-duty use.
