How much oil do you put on a nitro RC air filter?

For a nitro RC air filter, you typically apply a few drops of air filter oil evenly across the foam, ensuring it is well-saturated but not dripping. It's important to avoid over-oiling, as excess oil can trap dirt and debris rather than filtering it effectively. Allow the oil to soak in for a few minutes before reassembling the filter. Always refer to the manufacturer's guidelines for specific recommendations.
