DNJ Engine Intake Valve P/N:IV121
DNJ IV353 intake valve for the 1998-2004 Isuzu Rodeo V6 3.2L and other vehicles lets the air-fuel mixture into the combustion chamber. It opens at the intervals the camshaft sets and closes again to seal the chamber.
Rough idle, misfires or lost power can mean a worn engine intake valve, though a weak valve spring or a worn camshaft lobe can be behind the same signs, so find the cause before replacing anything.
The 1998-2004 Isuzu Rodeo V6 3.2L, the 2002-2003 Isuzu Axiom V6 3.5L and the 2001-2003 Isuzu Rodeo Sport V6 3.2L each take twelve of these valves, and many other vehicles are covered too. This listing is one valve, a direct-fit replacement made to meet or exceed OEM quality standards. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.
