Air Filter Oil Blue 12oz

Walker Engineering Air Filter Oil Blue 12oz is a specialized lubricant designed for foam air filter elements used in performance intake systems, off-road vehicles, and high-flow applications. This blue-colored filter oil coats foam media to trap dust, pollen, and debris while maintaining optimal airflow to your engine. Whether you're maintaining a lifted truck, a track-prepped race car, or an adventure vehicle, this 12-ounce bottle provides the right viscosity and adhesion to keep reusable foam filters performing at peak efficiency.

The blue formula is engineered to evenly distribute across foam surfaces, creating a consistent trap layer that captures contaminants without restricting air density or creating excessive backpressure on intake sensors. Unlike disposable paper filters, foam elements demand regular re-oiling to restore their filtration properties after cleaning. Walker Engineering's proprietary blend balances tackiness with low volatility, meaning the oil won't drain excessively during highway driving or high-RPM operation, yet releases trapped particles when the filter is submerged and agitated during the cleaning cycle.

This product is ideal for enthusiasts running aftermarket intake kits, vehicle owners maintaining oiled-foam cold-air intakes, and mechanics servicing off-road or motorsport machines where washable filters extend service intervals and reduce replacement costs. A single 12-ounce bottle treats multiple filter elements, making it economical for routine maintenance schedules. Compatible with all standard foam air filter designs, this Walker Engineering oil works across automotive, light truck, and recreational vehicle applications where performance and durability matter.
