Those of you who live down south can testify as to what a mess pollen season is. And if you think it's bad for you, consider how your Nissan air filter feels about all that dust floating around. Pollen and airborne debris can clog a stock paper Nissan air filter surprisingly quickly, and if bits do get past the Nissan air filter, they act just like fine sandpaper in your engine. So if you live where airborne pollutants are rampant--or you just haven't checked in a while--be sure to change your Nissan air filter frequently. Installing a new disposable paper Nissan air filter is a good choice. You'll get excellent filtration and decent flow from a plain OE style Nissan air filter, at least for a little while. The problem with a stock-style Nissan air filter is that its efficiency diminishes very quickly. A better choice is to install a high-flow gauze Nissan air filter. These cotton or foam Nissan air filters feature a reusable element so you don't have to install a new Nissan air filter every year. And a high-flow Nissan air filter will generally provide more power and filter out smaller debris without clogging. Stock or high-flow, the call is yours. We figure that installing any new Nissan air filter is a step in the right direction. That's why we're happy to supply you with all the Nissan air filter products you could ask for, at discount prices every day.
