What This Air Filter Helps Address

• Restricted airflow from a dirty or clogged factory air filter
• Routine replacement needs on classic Ford, Mercury, and Lincoln engines
• Frequent filter replacement costs on reusable-filter applications
• Loss of intake efficiency caused by aged paper media
• Maintenance demands on vehicles that use a round drop-in air filter

Installation Notes and Tips

Install the E-1570 in the factory air box after confirming the round filter dimensions match your housing. Because this filter is pre-oiled, avoid adding oil before installation. After cleaning, re-oil with 1.39 oz (41 ml) as specified by K&N. Verify fitment carefully on vehicles with special notes such as police package, ram air, Rochester carburetor, or 4-barrel carburetor configurations.
