Engine Air Filter Replacement on Nissan Altima 2021
I replaced the air filter on my Nissan Altima 2021. Typically, you want to change your air filter every 12 months or every 12 thousand miles. The purpose of the air filter is to prevent dirt and air from getting around the filter and into the air intake inside the vehicle.
