Detailed Description

The K&N E-1250 engine air filter uses a layered oiled cotton media design to balance airflow and contaminant capture. Its round shape, open top style, and flexible frame support a factory-style drop-in fit, while the 3.5-inch height, 11-inch outside diameter, and 9.25-inch inside diameter help define the application-specific sizing. This filter is washable and reusable, making it a serviceable replacement for owners maintaining older Dodge and Plymouth vehicles with compatible air box dimensions. The E-1250 is a practical upgrade for drivers seeking a reusable intake filter with K&N filtration technology.

This part cross-references Baldwin PA2052 and Dorman - HELP 42049 for the same application.

What It Is Used For

• Replacing a clogged or restricted engine air filter
• Restoring normal intake airflow in the air box

• Maintaining filtration in classic Dodge and Plymouth intake systems
• Supporting routine air intake service on vintage trucks and vans

Installation Notes and Tips

Install the E-1250 in the factory air box after confirming the filter shape and dimensions match the housing. Because this filter is pre-oiled, handle it carefully during installation to avoid transferring excess oil to surrounding components. Re-oiling is required during service using the specified amount listed for this filter.
