What is a Engine Air Filter?
The air filter stops impurities from the air sucked in by the engine and helps maintain the appropriate engine power, torque, and low fuel consumption.

If not for the filter, polluted air - full of pollen and street dust - would go straight into the combustion chamber. Engine impurities act like abrasive paper and cause damage to piston rings, bushes, and cylinders.

You should change the air filters at least once a year or every 12,000-15,000 miles, whichever comes first. If you drive in dusty/dirty conditions, you may be required to change your filter more often. Some filters are marked with a service life indicator that changes color when it's time to be replaced.

Signs You Need a New Car Air Filter
  • It Looks Dirty.
  • Your Car Doesn't Have as Much Power. 
  • You're Paying More at the Pump.
  • You Smell Gas When You Start Your Car.

What can happen if you dont change your air filter in your car?
When the air filter gets too dirty, it will get clogged and the engine won't be able to suck up enough air to the combustion chamber. When this happens, the engine will use more gas and less air, which will result in poorer performance and a drop in fuel efficiency
What is a Cabin Air Filter?
​
What does a cabin air filter do? Located on most vehicles behind the glove compartment, the cabin air filter is responsible for filtering the air that enters the cabin of the vehicle through the heating and AC system. This piece of equipment is critical to keeping air quality healthy inside your vehicle, as it filters out things like:
  • Dust
  • Mold spores
  • Pollution
  • Pollen
Over time, a clogged cabin air filter will become inevitable, which will affect your vehicle’s interior air quality.
Unfortunately, many people don’t even realize they have a cabin air filter, much less that it needs to be replaced! It’s essential to keeping your cabin’s air quality high, though, so it’s something you’ll want to stay on top of.
The time period for replacing your cabin air filter is dependent on the make, model, and year of your vehicle, so you’ll want to check your owner’s manual for verification. In general, though, most cabin air filters should be replaced somewhere between every 15,000 and 30,000 miles. You may also notice any of the following signs:
  • Reduced air flow when climate control systems are on
  • Lingering unpleasant odors
  • Increasing dust settling on vehicle surfaces
What is fuel filter?

A fuel filter acts as a permeable barrier that cleans the fuel of impurities, sediment, contaminants, and rust before they have a chance to get inside the fuel injection system and ultimately inside the engine of your vehicle. The fuel filter can be a cartridge with filtering material composed of paper inside.

Generally, it's a good idea to replace your fuel filter every two years or 30,000 miles. There are also diagnostics your technician can perform, such as fuel pressure tests, that can indicate whether or not the fuel filter is in good shape.

​What are the symptoms of a fuel filter being clogged?
A clogged fuel filter causes low fuel pressure that results in a lean fuel condition and engine misfire. This can result in poor fuel mileage, rough idling and possibly cause the check engine light to come on.
