There is no charcoal impregnated engine air filter. The OEM air filter is dry paper, the Performance Air Intake is oil impregnated. K/N also makes one that is oil impregnated cloth filter. The air filter size is still OEM, since you are retaining the original air box where the filter is mounted on.
