Most vehicles depend upon filters to screen out impurities for the proper functioning of the vehicle. Let's talk first about Air Filters, because your engine operates on an air to fuel ratio of about 15 to 1 a defective or clogged air filter is a thief of your car's performance capability.

You can check the condition of your filter by removing it and gently tapping on a flat surface to remove surface dirt. Then hold up your air filter to the light, if little or no light comes through it's time to replace your filter. If it is torn or punctured, even with a pinhole, your engine will be receiving unfiltered air which in time will take its toll. The replacement rule of thumb is every 15,000 miles. 

Your car's oil filter is also important to the smooth functioning of its engine, because it keeps solid particles or foreign materials from reaching your engine's moving parts to create wear. Follow your car's manufacturer's recommendation for replacement intervals bearing in mind that severe driving conditions will require more frequent replacements. 

  • Last but by no means least, don't neglect your gas filter.
  • Clogging will show up in starting, stalling, and sluggish performance, plus a noticeable reduction in top speed.
