371-1806 Air Filter C13, C15, C18 3406B, 3412, 3412C, 3512 Engine parts
371-1806 air filter is essential intake system component for CAT construction machinery and excavator diesel engines. It intercepts sand, dust, leaf scraps and airborne particulate contaminants before air enters combustion chamber, avoiding cylinder scuffing, piston wear and turbocharger damage. Replacing clogged air filter recovers engine rated power, reduces excessive fuel consumption and prolongs engine service life. OEM standard overall dimension supports direct plug-and-play installation without refitting.
