Air Filters

About Kaltreo air filters

Air filters keep abrasive dust out of the intake so it can't score cylinders, rings and turbo components. Kaltreo elements match OE dimensions and seal type, and many platforms pair a primary element with an inner safety element for high-dust sites. Service by the restriction indicator rather than a fixed calendar — a clogged element chokes airflow and raises fuel burn.

How to read a Kaltreo cross-reference

Every Kaltreo part lists the Fleetguard number it replaces plus interchange numbers from other brands (Wix, Baldwin, Donaldson, Mann and more). Find your current filter's brand and number — in a card or with the search above — and the matching Kaltreo part is the direct replacement. Confirm thread size, gasket dimensions and valve settings on the part page before ordering.

When to replace: by the restriction indicator, roughly every 500–1,000 running hours; inspect at each service. See the filter replacement schedule guide for full intervals, and always follow the engine maker's manual.
