Purolator is offering automotive service professionals its microfiber media technology within the Group 7 by Purolator brand. Microfiber technology filtration media incorporates a more complex matrix of passages that oil must navigate before reaching critical engine parts, the company said. The filter design is said to provide better filtration in a unit that is smaller and easier to install in newer cars that have limited access space. Just four part numbers now cover the same vehicles that previously required seven part numbers, reducing inventory needs, according to the company.
