Your Infiniti is a precisely engineered, fine running machine, but to keep it that way, performing the basic and scheduled routine maintenance and repairs, such as replacing the Infiniti air filter, must be done consistently. Many of those basic tasks take just a short time to complete, and changing your Infiniti air filter is one of the quickest and simplest of the routine maintenance that your vehicle needs, usually taking just minutes to perform. However, don't let those few minutes distract you from just how important a clean, good quality Infiniti air filter can be to your vehicle. The function of your combustion system relies on a steady flow of clean air, supplied through your Infiniti air filter. When your Infiniti air filter becomes dirty or clogged, your combustion system doesn't get the air it needs to maintain the delicate air-to-fuel ratio that leads to an efficient burn and a properly performing vehicle. Some of the symptoms that you'll be likely to notice when your Infiniti air filter isn't functioning as it should are related directly to the relationship between the air filter and the combustion system, including hesitation, rough idling and running, a sense of decreased power, increased fuel usage and decreased fuel mileage. We carry an excellent selection of Infiniti air filter replacements, ranging from standard, stock replacement options of a quality that can be depended upon to perform as well, if not better, than the one you'll be replacing and also we offer some higher performing choices.
