Perkins 26510214 Air Filter – OEM Drop-In Finned Primary Element

Easy fit & seal — About 392 mm tall, with an outer diameter of 154.7 mm and inner bore of 89.4 mm, it drops right in if your housing matches and the gasket surface is clean. The finned top helps it lock into place—no trimming, no fuss.

Designed to protect — Built to OEM standards, the 26510214 keeps dust out of sensitive parts like injectors and turbos. You can’t change how dusty the environment is—but at least the engine stays clean.

Fits your engine lineup — Common on Perkins 1000 series (e.g. 1006-6T), 4.236, 6.354/T6.354, and V8.540 series—those gensets and industrial engines running long shifts.

Cross-reference savvy — Interchanges with Fleetguard AF1733KM, Baldwin LL2418-FN, Donaldson P182059, and others across aftermarket suppliers—makes stocking easier.

Installer tip — Always clean the housing before seating. Sit the filter straight, give a light twist to settle the fins, and don’t blow-clean or reuse old elements. That just lets grit sneak in.
