Air Filter Cleaner Gallon

The Walker Engineering Air Filter Cleaner Gallon is a professional-grade solvent engineered for mechanics and automotive enthusiasts who demand clean, efficient air filtration systems. Whether you're maintaining stock OEM filters or running high-flow performance units on modified vehicles, this gallon-sized cleaner delivers the cleaning power needed to restore filter media to optimal condition. Air filters accumulate dirt, dust, and contaminants over time—especially in high-performance or off-road applications—and regular cleaning extends service life while maintaining proper engine breathing and fuel economy.

This cleaner works by dissolving accumulated particulate buildup without damaging filter media or gasket seals, restoring airflow comparable to a new filter at a fraction of the replacement cost. The solvent formulation is compatible with both pleated paper and foam filter designs, making it versatile across cotton intake filters, engine air filters, and cabin air applications. The 1-gallon bottle format (8.75 lbs net weight) provides ample cleaner for multiple filter service cycles, reducing the per-application cost and making it ideal for shops, fleet maintenance, or dedicated enthusiasts who service filters regularly.

Technicians and DIY builders benefit most from keeping Walker Engineering Air Filter Cleaner on hand during routine maintenance intervals or when troubleshooting airflow restrictions on turbocharged or naturally aspirated builds. The cleaner is particularly valuable when paired with performance modifications—fuel system tuning, engine breathing upgrades, and custom intake manifolds all rely on unobstructed air delivery, and filter cleaning ensures no unnecessary restriction undermines those investments. Safe handling and proper ventilation are recommended during application; refer to product guidelines for detailed mixing ratios and soak times based on filter condition and type.
