Air Filter – Z-83-401FR

The Intrupa flame-retardant air filter, part 83-401, is designed as an intake element for internal-combustion forklift engines. It sits in the engine air intake and traps the dust, grit, and airborne debris a lift truck pulls in while working, keeping abrasive particles out of the cylinders and off the intake tract where they would otherwise accelerate engine wear.

Weighing about one pound, it is a wide-fitment element that replaces original air filters across the major forklift makers, which is what makes it useful across a mixed fleet rather than a single machine. It matches Nissan numbers 16546-FJ100, 16546-FJ170, and 16546-GE20A, Toyota 00591-45315-81, Yale 220028173 and 902166802, Hyster 2034117 and 8767408, Komatsu 3EB-01-38730, Clark 1805375, Crown 364200-014, and Mitsubishi 91B61-00112, and it also covers JLG and Genie aerial and telehandler intake applications that share the same element, so one filter serves counterbalanced forklifts and boom or telehandler platforms alike.

A clogged air filter chokes the engine, cutting power and raising fuel burn, which is the signal that the element has loaded up and needs replacing on the service interval. Match the filter by any of the equipment numbers above and the fit is confirmed by the reference itself.
