Replacement Air Filters Reviews:For all of you that have ever gone to get the oil changed in your car, you know how it can be when the service guy starts asking about your air filter. Like many people, you may not have a clue what it even does let alone where it's located under the hood. We often say "go ahead and replace it" and it costs another $15 bucks or so. Many times they could be cleaned and used again, but the salesguy doesn't tell you that part. I started replacing the air filters in my cars years ago since I found out how easy it is. With the advent of websites like Youtube, you can watch a video of 'how to put in a replacement air filter' and be done with it in about 10 minutes of your time. You can also buy a better quality air filter that will last the entire time you own your car - with proper cleaning of course. Replacement air filters are fairly cheap and on some cars you will find that the overall miles per gallon you are getting increases. I buy all my air filters online at Amazon.com because they have an easy to use "parts finder" section of their automotive directory that lets you search by your vehicles make and model.
Choosing a Replacement Air Filter - The air filter is part of the intake system in your car and is crucial to the fuel/air mixture that your engines needs to run at the highest level. Air filters tend to get dirty overtime as they do their job of filtering out dirt and debris. Many are cheap enough that you can simply replace them while others (see below) are better quality and can be cleaned and used for years. Car buffs tend to buy the more expensive air filters from companies like K&N because they are looking for superior performance (things like acceleration and MPG improvement). The higher quality replacement air filters will cost more and potentially save you a few bucks down the road. The theory goes that the high flow air filters from K&N work better on cars with lots of HP (horsepower) therefore delivering more power when the driver needs it. There have been dozens of reviews done on air filter performance in cars - the ones from Bobistheoilguy.com and Autoblog are worth a look and websites like About.com and Carreview.com go over all the details on the latest car air filters for intake systems. The good news for consumers is that the price for these products is not that expensive and considering it's purpose, it's not a bad idea to replace your air filter with a better quality product every few years. Most car supply stores like Napa Auto Parts and AutoZone tend to carry all the leading brands. You can browse the best selling replacement air filters here.
