Baldwin PA2518 Automotive Air Filter

This Baldwin Filters PA2518 is a round outer engine air filter designed for automotive applications. It serves as a direct replacement element for compatible filter housings. The unit is supplied new and ready for installation in vehicles that specify this part number.

Round design with 12 1/8 inch outside diameter

The filter features a round profile with an outside diameter of 12 1/8 inches and a height of 20 3/8 inches. These dimensions determine fitment inside the factory air cleaner assembly. Verify the housing measurements and part reference before purchase to ensure correct sealing and airflow.

Low restriction media supports engine breathing

The pleated media is engineered to capture contaminants while maintaining steady airflow to the engine under normal driving conditions. A clean element reduces intake restriction, helping the engine operate efficiently without adding audible noise or parasitic load. Regular inspection and replacement protect downstream components.

Questions about this item

What does the 20 3/8 inch height mean for installation clearance?

The filter stands 20 3/8 inches tall, so the housing must provide at least that much vertical space for the element to seat and seal correctly.

How does the 12 1/8 inch outside diameter determine fitment?

The 12 1/8 inch outer diameter must match the housing bore exactly; a mismatch will prevent the radial seal from forming and allow unfiltered air to bypass the element.

What physical space is needed to mount the round PA2518 element?

A cylindrical opening of 12 1/8 inch diameter and 20 3/8 inch depth is required, with no obstructions that would interfere with the round filter body or its sealing surfaces.
