Had a little trouble finding the exact item via searching the K&N website, but once found, ordered, delivered, no problem.

This is the best way to buy air filter oil. It is cheaper than buying aerosol cans.

We have 4 vehicles with K&N filters, so having the oil in a larger container is more practical for my needs.

Order shipped fast. I will use a cheap Harbor Freight paint sprayer to apply. Works like a charm.
