Bosch Wiper blades for Hyundai Santro

 PB helped me out with the following info:

Attached is the wiper blades size for Santro
List shows 20" on Driver side and 16" on Passenger side

TYPES OF BOSCH WIPERS
Bosch Clear Advantage — a flat-blade / beam-style wiper. Designed to give uniform pressure across the windshield, better contact, smoother wiping, and more streak-free clearing (especially good in heavy rain or at high speeds).

Bosch ECO (conventional / bracket-frame wiper) — a more traditional wiper with a metal (or mixed) frame + rubber blade. Usually more budget-friendly and covers basic everyday wiping needs.

AMAZON LINKS
Bosch Clear Advantage 16"

Bosch Clear Advantage 20"

Bosch ECO 16"

Bosch ECO 20"

I have been using Bosch ECO, and it works well. 

Will try Clear Advantage next time.

And, found that there were video guides on how to fit the blades, in the amazon listings. Also available on youtube, at Bosch ECO and Clear Advantage.

On my (new) Santro, the 20" blade seems a bit short. Perhaps I'll try the 21-inch blade next time.
