"BIGGIE" Oil Filter Adapter (Buick V6)
This will allow you to use a large capacity oil filter in place of the stock oil filter.
This increases idle oil pressure, has over 3 times the amount of filter media area and will help keep oil from continually bypassing the filter through the factory bypass.
Every car needs one.
