Automotive Spin-On Oil Filter
The Baldwin B43-S is a full-flow spin-on oil filter designed for automotive lubrication systems. It fits applications requiring an M18 x 1.5mm thread and a 3-1/2 inch overall length. The unit targets standard passenger car and light truck maintenance intervals.
18 Micron Filtration Capacity
Rated at 18 micron, the element captures fine contaminants while maintaining adequate oil flow for full-flow lubrication circuits. The attached G449-B gasket and integrated anti-drainback valve support consistent priming and prevent dry starts. Headroom diminishes in heavily modified engines producing excessive debris loads.
Anti-Drainback Valve And Gasket
The factory-fitted anti-drainback valve retains oil in the filter after shutdown, reducing wear during cold starts. The pre-attached G449-B gasket eliminates separate seal installation and ensures a reliable mating surface. No additional hardware or adapters are required for the specified thread size.

Questions about this item
Will this B43-S filter fit the M18-1.50 thread on my existing AMC engine block?
Yes, the thread size is M18-1.50 and the manufacturer lists AMC among the compatible applications.
How can I verify the 18 micron full-flow filtration is working after installation?
Check for normal oil pressure at idle and operating temperature, and confirm no leaks at the G449-B gasket seal.
Does the box include the G449-B gasket or must I order it separately?
The G449-B gasket is attached to the filter, so no separate purchase is needed.
