(888) 312-8812 Login SignupThe Fleetguard OptiAir Air Filter combines primary-stage intake duty with an OptiAir element format for routine engine-air service. In that role, the Fleetguard AF26103 filters incoming air before flow continues through downstream intake components. A 9.84-inch largest outside diameter and 16.10-inch overall length provide two physical housing references. Those dimensions support the fit check while primary-stage function keeps the selection tied to the correct intake position within the air-cleaner housing.
