Baldwin Filters BT368 Air Breather

The Baldwin Filters BT368 is a spin-on automotive air breather filter designed to protect engine crankcase ventilation systems from airborne contaminants. It fits applications requiring a 3-11/16 inch outside diameter and a 3-7/32 inch height. This component suits maintenance on compatible vehicles and equipment where a direct replacement breather element is specified.

Thermals noise and power

As a passive filtration component, the BT368 generates no heat, noise or electrical draw during operation. Its spin-on design allows straightforward installation and removal without specialised tools. The filter media manages airflow while trapping particles, contributing to stable crankcase pressure under normal running conditions.

Replaces worn breather elements

This filter replaces a used or clogged spin-on breather of the same dimensions and thread specification. The upgrade is worthwhile when the existing element shows restriction, oil saturation or damage that could allow unfiltered air into the crankcase. It is not intended for applications requiring a different mounting style, flow rating or filtration efficiency.

Questions about this item

How do I install the BT368 spin-on breather filter and what step is often missed?

Thread the 3 11/16 in. diameter canister onto the mounting stud by hand until the gasket contacts the base, then tighten an additional 3/4 turn; skipping the final torque step causes leaks.

What maintenance does the BT368 breather filter need and when?

Replace the entire spin-on canister at the engine manufacturer’s recommended service interval; the element is not serviceable separately.

What limit appears first on the BT368 under sustained high-blow-by conditions?

The filter media saturates with oil mist, increasing crankcase pressure and triggering the restriction indicator before structural limits are reached.
