The FH and FX series fitted to mowers and small tractors, including FH601V through FH770D, FX651V through FX1000V, and FD731V, FD750D and FD791D.

Yes. The inner element only protects the engine while the outer one is intact, so the pair goes in together and the pack supplies both.

Description

Product Overview

Air filter set AF25552-AF25551 pairs an outer element with an inner one for Kawasaki FH and FX engines. The outer element measures 105 mm outside diameter and 61 mm inside diameter, and the two together replace 11013-7044 and 11013-7045, the numbers Kawasaki prints on the air box of these engines.

Key Features

Two elements, two stages — the outer element takes the bulk of the dust and the inner one backs it up, so a holed outer filter does not put grit straight into the engine.
105 mm outside diameter — seats on the air box spigot of the FH and FX engines without a spacer.
61 mm inside diameter — the bore that clamps over the intake throat, the same as the OEM element.
Pleated paper behind metal mesh — the mesh holds the pleats apart under suction so the media keeps its surface area.
Sold as a pair — inner and outer arrive together, which is how these engines are serviced.
