Oil Filter: The frequency you should clean your filter will depend on your
driving conditions. It is recommended to check your filter at every oil change
or 3,000 miles. If there is a buildup of dirt as thick as the wire mesh, then
it’s time to clean your filter.
To properly clean your oil filter, we recommend the S&B Precision Cleaning &
Oiling Kit (located in the Parts Sold Separately Section of our website,
www.JLTtruecoldair.com).
