There are two main air filters at work in your vehicle. The first and foremost is the combustion air filter.

This air filter is situated in the engine compartment’s air intake, where it is responsible for cleaning the air brought in from the outside before it reaches and enters the engine itself. Why is this important? Simple. Your internal combustion engine relies on the presence of air to operate. The “combustions” inherent in the title are dependant on the interaction of fuel and air – which is why your vehicle is filled with components that help provide your engine with the correct amounts of air in order to function smoothly. If your engine is sucking in dirty air, however, its delicate mechanical components can quickly become clogged with dust and grime. For this reason, you need a great combustion Toyota 4Runner Air Filter in place at all times – because without it, you cannot provide your engine with the clean, debris-free air it needs and deserves. The second major air filter in your vehicle is the cabin air filter – which, not surprisingly, is responsible for the quality of air that enters the passenger cabin of your vehicle.Any way you slice it, you need to replace your Toyota 4Runner Air Filter every time you change your oil – no questions asked.
