There are many maintenance parts on your Infiniti that you should be paying attention to and replacing on a regular basis. The air filter is one of them. These parts help to remove pollutants from the air your car uses and keeps your engine running smoothly. According to most vehicle manufacturers, you should replace the air filter of your car every ten to fifteen thousand miles. Still, if you live in a dusty, rural area or cannot avoid driving on gravel roads, you might want to change the air filters more frequently. You can consult your car's manual for the recommended time frame. A clogged air filter prevents clean air from entering the car engine, causing a whole host of problems including inefficient combustion. There are a range of signs you can look for that indicate you need an air filter replacement. One includes reduced fuel economy, because your engine is compensating for a lack of clean air by using more fuel. When looking to buy a new filter, it's important to get it straight from the manufacturer. Only an OEM air filter is going to install in your vehicle correctly and last a long time.
