NWP Air Filter (Heavy Duty Felt) for Husqvarna 371, 372XP Chainsaws (Replaces 503818001)

Replacement air filters from NWP. Heavy duty air filters give you the highest performance for your Husqvarna chainsaws, due to their large surface area. These filters have a non woven felt material (also known as flocked or fleece) around the pleated width of the filter that picks up fine particles of dust. The pleated material gives greater filter surface area, which gives your carburetor better airflow. They filter very well (which is a good thing), but tend to ice up in sub freezing conditions. We recommend using a nylon mesh filter air filter when sawing in frozen conditions. These air filters are oil-less. Filters can load up quickly, so be sure to have a couple of spares handy.
