Outer Inner Air Filter for John Deere
This two-stage air filter set protects John Deere Industrial engines by removing abrasive contaminants from the intake air stream. The outer element handles bulk filtration while the inner element serves as a safety backup for critical engine protection. Cross-referenced for several 4.5L diesel models, this kit ensures consistent air flow for maintained combustion.
Overview
This Outer Inner Air Filter is a dual-element service kit built for John Deere diesel engines to ensure clean airflow under heavy loads. The outer filter captures up to 99% of incoming particles while the inner filter acts as a fail-safe barrier. Suitable for a range of 4-cylinder and 4.5L power units, this Outer Inner Air Filter delivers reliable performance for agricultural and industrial equipment.

Good To Know
Q: What is the purpose of the inner filter? A: The inner filter acts as a safety element to protect the engine in case the outer filter is damaged during service. It also catches any fine dust that may pass through the primary element.
Q: Is the filter washable? A: No, this is a dry disposable filter. Do not attempt to clean or reuse it, as washing will damage the media and reduce filtration efficiency.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
