Air Filter Oil Gallon

Walker Engineering Air Filter Oil Gallon is a specialized lubricant formulated for pre-oiling foam air filter media in high-performance automotive applications. Whether you're building a race engine, maintaining a heavily modified street car, or servicing aftermarket air intake systems, this blue-tinted oil is essential for ensuring optimal filter performance and engine protection. The 1-gallon bottle provides ample supply for multiple filter treatments, making it a cost-effective choice for serious enthusiasts and professional shops alike.

This air filter oil is engineered to coat foam filter elements uniformly, trapping airborne contaminants while maintaining excellent airflow characteristics critical for engine breathing and power delivery. The proprietary blue formulation indicates a premium-grade synthetic or semi-synthetic base that resists breakdown under high intake temperatures and extended service intervals. Walker Engineering's design ensures the oil adheres permanently to filter foam without migrating into the intake manifold, preventing fuel mixture contamination and combustion chamber deposits—concerns that plague inferior filter oils in modified engines running elevated boost or extended RPM ranges.

Track competitors, drift builders, and street enthusiasts using reusable foam air filters depend on Walker Engineering Air Filter Oil Gallon to maintain peak filtration efficiency across repeated clean-and-oil cycles. The product integrates seamlessly with all major foam filter platforms—K&N, BMC, Green Filter, and OEM reusable designs—making it universally compatible for turbocharged, supercharged, and naturally aspirated builds. At 7.46 lbs per gallon container, this bottle delivers professional-grade protection for engines demanding reliable air quality without compromising intake flow.
