Wiper Blade Set Bosch Twin 420

Description

Bosch Twin 420 – wiper blade set built with frame assembly, lengths 425 mm & 425 mm.
Elevate exceptional visibility all year long with the Bosch Twin 420 dual windshield wipers — designed to conquer heavy rain, icy sleet, snowfall, and extreme temperatures effortlessly.

The wiper blade boasts a sturdy steel skeleton with flexible rocker arms, crafted to provide precise downforce on curved glass. The synthetic EPDM wiping edge is firmly anchored in a U-channel, delivering a tight seal across the arc. User-friendly blade swaps and broad vehicle fitment make it a budget-friendly solution for classic cars. It features 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.
