What is the size of the BMW Z4 windshield wiper?
3 Answers
BMW Z4's left front wiper size is 22 inches, and the right front wiper size is 21 inches. The length of car wipers is expressed in inches. According to the conversion of 1 inch = 25.4 mm, you can measure the length of the wiper with a ruler and directly convert it. Here is some related information about the BMW Z4: 1. Body dimensions: The vehicle dimensions are 4239mm*790mm*1291mm, with a wheelbase of 2496mm. 2. Powertrain: It uses a 3.0-liter twin-turbocharged 6-cylinder engine from BMW, with a maximum output power of 335 horsepower and a peak torque of 332 lb·ft (momentary maximum can reach 369 lb·ft). It is paired with a 7-speed dual-clutch automatic transmission. 3. Safety features: The BMW Z4 comes standard with a tire pressure monitoring system, which can alert in time to avoid severe losses. It also features a two-stage brake signal light, where additional LEDs (light-emitting diodes) in the brake lights are activated during emergency braking to enhance the warning to vehicles behind.
Having run an auto repair shop for years, I frequently encounter BMW owners coming in for wiper blade replacements. For the BMW Z4, the wiper sizes vary by model year: For 2003-2008 E85/E86 models, the front wipers measure 24 inches (610mm) for the driver side and 18 inches (450mm) for the passenger side. For 2009-2016 E89 models, the driver side remains 24 inches, but the passenger side increases to 19 inches (480mm). It's best to measure the old wipers before removal - use a steel tape measure from the center of the mounting clip to the other end of the wiper blade. Pay special attention to the connector type when selecting new blades: older models use straight insert connectors while newer models feature hook-style attachments - getting the wrong type will prevent installation. For maintenance, regularly clean tree sap and oil film from the rubber blades to extend their lifespan.
When I last replaced the wipers on my 2012 Z4 myself, I specifically checked the original manual and confirmed it's 24 inches on the left and 19 inches on the right. Later I found that searching for 'Z4 E89 specific wipers' on Taobao gives perfect matches at 40% cheaper than physical stores. Installation is super easy: first lift the wiper arm to a vertical position, then press the connector clip and pull it off. When installing new wipers, a 'click' sound means it's properly seated. Remember to place a thick towel under the wiper arm before lowering it back onto the glass - I once accidentally cracked a friend's windshield by dropping the arm, costing me 3,000 yuan. Wiper lifespan depends heavily on parking environment, cars parked under trees may need replacement every six months.
