3.2.2) What is a K&N filter and what will it do for my RAV4?
A K&N air filter is a replacement made of layers of cotton gauze
between a wire mesh to hold its shape and covered (saturated) with an
oil. It passes more air than a paper filter, and due to the oil,
filters better than a paper element. It can give you more power at
higher RPMs and increase your MPG slightly (~1MPG).
The filter is pre-oiled and ready to install. Eventually you will need
the cleaning and re-oiling kit, which costs about US$20 and comes with
spray cans of cleaner and oil. K&N warranties their filters for 1
million miles when properly cared for, so the overall cost can be
dramatically lower when compared to disposable paper air filters.
Filter # 33-2030 is the same size as the stock RAV4 air filter.
Installing this is the same as installing a Toyota filter.
