Bosch Engine Oil Filter P/N:3976
Bosch 3401 oil filter for the 1987-1990 Jeep Wrangler 4-cylinder 2.5L or 6-cylinder 4.2L and other vehicles screens harmful contaminants out of the oil. This spin-on Bosch oil filter is made to protect the engine through the vehicle manufacturer's longest recommended oil change interval.
Oil seeping around the filter's gasket, or a filter that has run past your change interval, are reasons to replace this engine oil filter. A low oil pressure warning alone does not prove the filter is at fault, since a low oil level can cause it too.
It also works as an oil filter for the 1985-1987 Jeep Cherokee 4-cylinder 2.1L, the 1986-1990 Cherokee 4-cylinder 2.5L and the 1987-1990 Cherokee 6-cylinder 4.0L, and as an oil filter for the 1990-1995 Chevrolet Corvette V8 5.7L. Every one of these engines takes a single filter. If your own car is not named here, enter it in the "Vehicles it fits" section to see whether it takes this filter.
