How to Change Your Car's Air Filter

A car is similar to a human in the way it breathes, burns energy and expels waste. Changing an air filter on your car is a vital necessity and one which if left for too long, restricts the car's breathing and can cause major problems. Having new and regularly replaced air filters, ensures your car's engine has fresh, unimpeded air flowing through it.
Here is how to change your car's air filter:

  1. Purchase the correct air filter for your car, model and engine size. Consult your owner's handbook to retrieve the part number. Have the correct tools for the job at hand before you start, which are: a flat-blade screwdriver, a Phillips screwdriver and an air hose compressor.
  2. Secure the car by placing the the gear lever into Park and by applying the parking brake. Open the bonnet (hood) using the in-car bonnet release and secure it with the prop rod.
  3. The air filter is usually shrouded with plastic tubing on the top of the engine. Older cars usually have large, circular compartments, while new, fuel injected cars have a square air filter housing. To make sure, check the owner's handbook for reference.
  4. Loosen the air filter housing, hose clamps and screws (making sure you remember or number them in there respective place). Take out the paper, gauze or cotton based air filter.
  5. Clean out the filter's housing, using an air compressor or a dry cloth if this is not an option. Vacuum out any loose dirt and dust, ensuring there are no particles left.
  6. Install the new filter, ensuring it is in the same direction and it is exactly the same as the old filter unit.
  7. Replace the air filter housing and all of the retaining screws and clamps. Make sure the housing is on straight and is secured. If it is not, then it could cause poor fuel efficiency.
  8. Double check all of the screws, clamps and housing parts are replaced properly, shut the bonnet and start the engine to ensure there are no strange noises.
  9. Check the filter after 200kms to ensure all of the fixtures are still tight. Re-tighten if necessary. Remember to change you filter every 15,000km or once a year.

Loss of mpg on 2006 legacy Subaru


A dirty air filter will prevent adequate air from entering the engine thus reducing gas mileage. Worn spark plugs or a weak spark (defective spark coils) can do the same. A defective "upstream" oxygen sensor (in the exhasut system) can lower fuel mileage. It forces the engine computer to guess at combustion efficiency without feedback from the sensor. It will err on the "rich" side to save the engine, which means it wastes gas. A "check engine" light will be "on" if that is the problem.

In winter, more alcohol is added to gasoline in cold climates to due to the lack of photosynthesis in the region (to make oxygen for us to breath.) Reduced fuel mileage results. Alcohol burns cleaner (and cooler) but it contains less energy (BTU) per gallon than "straight" gasoline. For example, E85 won't take you as far as a tank of regular gasoline.

If your car is designed to use 87 octane fuel, there is no need to use higher octane fuel. Higher octane fuels are for "high performance" engines with increased compression ratios. High octane fuel burns "slower" in the cylinder (to help avoid "detonation") so that the engine can take advantage is its greater compression ratio and advanced igntion timing to make more power. If your Legacy has a turbo, it will likely require the use of premium gasoline to avoid "detonation" under boost. Otherwise, "cheap", 87 octane gas is fine.

Burning oil....


ge, not eenough oil changes through it's life. A often overlooked problem, is a clogged air filter, or the air ram leading to it. Kinda like running a marathon, without sucking in air, you collapse. The car,if it can't breathe...........you will BURN oil, gas, MPG.

Check engine light and spottering


I think you should start by changing the fuel filter, and changing plugs and wires, air filter and just go from there. If you don't have an engine light on, don't waste your time and money. You should also check the timing, and the timing belt. If it jumps a cog, it'll cause all of the above symptoms. The mass air flow either works or it doesn't, and when it doesn't... you're walking.

2003 Cavalier maintenance schedule


I would change oil, oil filter, rotate and possibly balance tires, flush transmission (if fluid is not dark brown or black), change fuel filter, pcv valve, air filter, wiper blades. If near 100k I would add Plugs and wires, and check into a coolant flush and possibly changing out theremostat. Its all dependant upon how much money you want to spend on your car. That list is pretty heavy on the ole wallet. However, I have listed the items to be done in order from greatest necessity to smallest necessity for you.
