Air Fltr Oil 8oz. Bottle

K&N Engineering Air Filter Oil 8oz. Bottle (Part No. 99-0533) is a specialized lubricant formulated to maintain and restore the performance of high-flow air filtration systems. This red-colored squeeze bottle delivers the precise viscosity and tackiness required to keep reusable cotton-gauge filter media properly lubricated, ensuring consistent airflow while protecting engine components from dust ingestion.

The 8-ounce format provides sufficient coverage for multiple filter applications or maintenance cycles. K&N air filter oil is engineered to resist breakdown under high temperatures and sustained airflow conditions, maintaining uniform oil distribution across the filter's cotton-gauge surface. The squeeze bottle design allows controlled application without oversaturation, preventing excessive oil carryover into the intake manifold or mass airflow sensor—a critical consideration for vehicles with electronic engine management systems that rely on accurate airflow measurement.

This product is essential for owners maintaining K&N reusable air filters or comparable high-flow filtration systems that require periodic re-oiling. Whether you're supporting a street vehicle modification, truck off-road upgrade, or performance engine build, keeping filter media properly conditioned extends service life and preserves the airflow gains these systems deliver. The 8oz. bottle is a convenient maintenance staple for shops, enthusiasts, and fleet operators who rely on washable filter technology.

Reusable air filters represent a long-term investment in both performance and sustainability; proper oiling keeps that investment performing as designed. K&N's formulation balances filter media protection with intake system reliability—critical where OEM air quality sensors are present.
