Wiper Blade Set Bosch Twin Spoiler 400 S

Description

Bosch Twin Spoiler 400 S – frame wiper blade set, 400 mm + 400 mm for streak-free wiping.
Engineered for all-weather performance, the wiper blade set 400 S guarantees crystal-clear cleaning across both blades in any climate.

Bosch 400 S comes with 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 faces higher wind forces, this efficient solution maximizes clarity where it matters most. The spoiler boosts downforce, ensuring a clean wipe at windy conditions. Great for budget-focused drivers, it delivers clear visibility.

The replacement blade features a robust metal frame with multi-pivot joints, crafted to provide even pressure distribution on curved glass. The synthetic EPDM wiping edge is securely bonded in a precision slot, delivering a streak-free clean across the arc. Refill-compatible design and universal compatibility make it a cost-effective choice for older models. 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.
