More About Air Filters

An air filter determines how clean and easily air enters the engine. For standard engines, it's mainly about maintenance and fit, while for modified engines, flow and intake temperature are also important.

Pay attention to the filter type, diameter, connection, placement in the engine compartment, and protection against hot air. An open filter often sounds sportier, but works best with a good supply of cool air.

Brands like K&N and similar filter brands are often chosen for replacement or a sportier intake setup.
