OEM INFINITI Air Filters Online

What Car Air Filters Do

Your INFINITI has two: a cabin air filter and an engine air filter. They help keep airborne contaminants from accumulating in your heater and AC system and on engine parts.

If your car or SUV didn't have an engine filter, for example, pollutants would build up in its air intake, on its fuel injectors, and even on its spark plugs. If it didn't have a cabin filter, dirt, dust, and allergens would pile up along its many ducts and on its vents, quickly clogging both.

In short, air filters help your car HVAC and engine work as well as they can. Unfortunately, filters can wear out -- that is, if they don't choke with debris. When they do, other problems follow. Luckily, there are signs it may be time to change them. Keep an eye out for the following.

Signs Car Air Filters Need Replacing

• A lit Check Engine light on your dash
• A dirty or degraded filter
• Congested filter fibers
• Unclean smells in your cabin
• Unusual engine noise
• A stressed engine
• Engine misfires
• A reduction in fuel efficiency
• Significantly increased emissions
• Heating and air conditioning malfunctions

When to Change a Car Air Filter

To help prevent these sorts of problems, replace both your air filters regularly, approximately every 12,000 to 15,000 miles. If you're seeing any of the symptoms listed, however, it's more than likely replacement time. Luckily, you can buy new air filters from INFINITI online, right here at our auto parts department.
