Wiper Blade Set Bosch Twin Spoiler 394S

Description

Bosch Twin Spoiler 394S – frame wiper blade set, 580 / 500 mm for maximum reach.
394S – an all-weather set of wipers built to handle rain, sleet, snowfall, and heat with consistent, long-lasting performance.

Bosch 394S features a driver-side spoiler. Many two-blade kits include only the driver-side blade with a spoiler, leaving the passenger blade standard. Since the driver’s side covers a larger sweep area, this cost-effective solution maximizes clarity where it matters most. The spoiler reduces lift, ensuring resilient performance at stormy weather. Ideal for urban and suburban use, it delivers robust performance.

This replacement blade delivers a sturdy steel skeleton with articulated pressure points, crafted to provide precise downforce on complex windshield shapes. The high-grade polymer wiping edge is securely bonded in a U-channel, delivering a tight seal across the arc. Easy-to-replace refills and universal compatibility make it a reliable pick for everyday vehicles. It incorporates a durable galvanized frame that resists corrosion and mechanical wear, a multi-pivot action that adapts to complex windshield curves and a simple rubber refill system that extends service life while reducing total cost of ownership. However, exposed hinges may freeze and clog with dirt during winter, at high speeds it can experience wind lift and increased noise, and natural rubber wears faster in sunlight whereas polymer composites command a higher price. Periodically clean and lubricate the hinges with a silicone spray every three to six months and replace the wiping edge every six to twelve months (or every four to six months in harsh climates). Perfect for mild weather, daily commuting and economical drivers, this blade ensures dependable performance, clear visibility and lasting value at an affordable price.
