Rugged Ridge pre-filter is designed to work with both the 3.6L and 3.8L XHD Modular Snorkel. The pre-filter
extends the engine filter life even in the dustiest environments. The pre-filter forces the air into a turbulence
which collects the heavier dust and moisture on the outside of the pre-filter bowl, where it is deposited. The
remaining clean air is drawn into the engine via the engine’s air filter.
