Fram Extra Guard oil filters use a thick, multi-fiber media and provide a maze to trap contaminants effectively on the first pass. Fram Extra Guard oil filters also feature engineered gasket material to provide top performance in all environmental conditions, and high-strength spiral center tubes that resist internal pressure buildup, preventing collapse. Their revolutionary new SureGrip no-slip finish makes the Fram Extra Guard oil filters much easier to grip during installation and removal--even with oily hands.
