Description

Bosch Twin Spoiler 503S – wiper blade set, 500 mm and 475 mm, featuring a frame assembly.
Engineered for year-round performance, the set of wipers Bosch Twin Spoiler 503S assures crystal-clear cleaning across both blades in any weather condition.

Bosch Twin Spoiler 503S wiper blades 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 efficient solution maximizes clarity where it matters most. The spoiler minimizes vibrations, ensuring a clean wipe at stormy weather. A smart pick for daily commuters, it delivers value-driven performance.

This replacement blade delivers a durable alloy structure with flexible rocker arms, engineered for precise downforce on curved glass. The high-grade polymer wiping edge is securely bonded in a precision slot, delivering a streak-free clean across the arc. User-friendly blade swaps and wide model coverage 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 assures dependable performance, clear visibility and lasting value at an affordable price.
