K&N Air Filter E-3033 for Ford F-250 and F-350 K&N Air Filter E-3033 for Ford F-250 and F-350
K&N Engineering has been designing, manufacturing, and enhancing High-Flow Air Filters for the automotive and motorcycle enthusiast since 1969. K&N's replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration.

The E-3033 was engineered specifically as a replacement air filter for K&N’s replacement air filter system, E-0780, designed for the 2003 to 2007 Ford F-250 and F-350 with a 6 liter engine. If you drive in extremely harsh conditions and just don’t have time to clean your air filter right away, having a spare might be the answer. Simply swap K&N air filters then clean and re-oil the filter with K&N’s cleaning kit when it is convenient for you.

The E-3033, replacement air filter, is made of cotton gauze layered between two epoxy-coated aluminum wire screens.  The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton’s microscopic strands. This allows virtually unrestricted airflow to your engine while providing excellent filtration to protect your Ford pickup.
