The SM 179 oil filter (part number SCT) is a classic spin-on filter in a metal housing. It is designed for powerful gasoline engines with displacements from 2.0 to 4.6 liters, which were widely used in American and Japanese vehicles.

This filter features an increased housing capacity, which is necessary for lubrication systems with large oil volumes and high circulation rates.

Specifications
Filter Type: Spin-on (full-flow).

Housing: Thick-walled steel bowl, resistant to pressure surges and external damage.

Valve System:

Anti-Drainback (Check) Valve: Prevents oil from draining into the oil pan, preventing dry engine starts.

Bypass Valve: Set to a specific pressure to ensure oil flow even in extreme cold or when the filter is heavily clogged.

Seal: Heat-resistant rubber gasket that maintains elasticity throughout its service life.

Key Benefits
High Flow Rate: Optimal for V6 and V8 engines requiring rapid, high-volume oil flow.

Deep Cleaning: Multi-layer filter media effectively captures wear debris and carbon deposits typical of high-power engines.

Reliability in Heavy-Duty Conditions: Designed for heavy-duty operation (towing, off-road driving).
