What's the 2018 Mazda 3 windshield wiper size?

Your 2018 Mazda3 is going to need to use a 24 inch driver's side blade and a 18 inch passenger blade. This will be the same for all models produced froM2014 and onward. Older models had a passenger blade that was one inch longer. The wiper blades are going to need to be changed out between every one to three years depending on how much use they get. If You live a bad weather environment it will likely need to be done every year. A replacement set will cost You between $15 and $30 but it's best to go for the higher end as they'll need to be replaced left often.
