What's the bmw e46 windshield wipers size?

The BMW E46 is the fourth generation of the BMW 3 Series, produced from 1997 until 2006. The specific wiper blade size will vary with which model within the 3 series You have, with some variations even coming between the coupe, sedan, and wagon variants. Generally, limited information is available with regards E46 wiper blade size without more information, such as configuration and body style. The best information I could find says the vehicle will typically require a 22 inch driver's side wiper blade, with a 19 inch passenger's side blade. The most important thing is that You match up the mounting method -- You'll need to ensure that the blade will be mountable on Your specific vehicle. If You have any other information about body style and year to share, I'd be glad to provide further help.
