NAPA oil filter SMTA

redFarmallboy · Mar 7, 2013

Does anyone know the NAPA oil filter number for a SMTA? It is a tall filter but my NAPA store shows 2 different filters that are about a half inch different in height. Thanks.

If it's a gas engine, and nothing's been changed, it should be 1125. Gasket is not included. Order 5070 if needed.

Housings and covers (and engines) sometimes have been swapped out over the years.

Info from NAPA's filter website:

Short narrow filter is NAPA 1172. 5070 gasket IS included.
Height: 5.594
Outer Diameter: 3.281
Inner Diameter Top: 0.480
Inner Diameter Bottom: 0.875

Tall narrow filter is NAPA 1125. 5070 gasket IS NOT included.
Height: 7.579
Outer Diameter: 3.264
Inner Diameter Top: 0.480
Inner Diameter Bottom: 0.875

Tall fat filter is NAPA 1155. 5074 gasket IS NOT included.
Height: 7.375
Outer Diameter: 4.188
Inner Diameter Top: 0.594
Inner Diameter Bottom: 1.281

Measure your old filter or housing & cover if you're unsure.
