Part # 38-2013S K&N Heavy Duty Washable Air Filter


Designed to Lower Restriction and Improve Horsepower
These commercial grade air filters are built from a new hybrid filter medium that incorporates some of the best characteristics of both cotton and synthetic non-woven technologies. They do not require any oil treatment and use a 3-D lofted filter surface to help reduce air filter restriction. Less restriction means more power and better engine efficiency. As air filter restriction goes up, an engine needs to expend energy "pulling" air through the filter. This is wasted energy that is no longer available for power at the wheels. Another air flow benefit with K&N HD air filters is that each time the air filter is washed, restriction is reduced whereas disposable air filters slowly increase in restriction throughout their service life.

This air filter appears to be a replacement for my current which I think is a NAPA 546664 the dimensions are close.
I have a Cummins 8.3L in a Monaco Diplomat 2003. Unfortunately I do not have Cummins ESN.

Yes according to your information and checking with the Monaco VIN the 38-2013S is the correct replacement air filter.
