Bully Dog RFI Pre-Filter
(1994 - 2005 Ford Powerstroke)

Our Price: $29.21

A prefilter repels water and large particles which helps maintain horspower levels between cleanings because it keeps the filter cleaner. Using a Prefilter also makes cleaning much easier; bugs, twigs, and dirt that make their way into the filter housing no longer get caught in the filter ribs.
