Good To Know
Q: How often should I replace the LF3970 filter? A: Replace it at every oil change interval recommended by Cummins, typically every 15,000 to 25,000 miles or equivalent hours based on duty cycle.
Q: Will this filter fit my 2007-2018 Ram with a 6.7L Cummins? A: Yes, the LF3970 is the correct oil filter for 6.7L Cummins engines used in Ram trucks from 2007 onward, but always confirm with your owner's manual to be sure.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
