The engine air filter is a rectangular pleated filter situated near the front of the engine compartment. Its purpose is to filter out particles like dust, dirt, bugs, etc. and only allow clean air into the engine.

The air filter is an important part because the engine needs clean air. Since the engine sucks in substantial amount of air, it's exposed to a lot of dust and debris if there's no air filter. The dust and debris will damage the internal engine components and wear out the engine faster. The engine air filter is an inexpensive way to prolong your engine's life.

  1. Filter material surface area

This guide covers each factor in more detail and will help you reach an educated decision.
