✨ Why Choose Bosch AeroTwin?

• Streak-Free Clarity – Even pressure distribution across the entire windshield

• Built for Monsoon – Weather-resistant rubber withstands heavy downpours and intense summer heat
• Plug & Play – Quick DIY installation with pre-fitted OE-style adaptors, no tools required

Worth flagging again: this A639S listing now shares the A6/A7/S6/S7/RS7 audience with your earlier A638S (3397007638) listing — both are 26"+21" but different adapters/part numbers. For SEO and to avoid customer confusion, I'd suggest putting the part number (A639S vs A638S) visibly in both product titles, and ideally add a short note on each page like "Not sure if you need A638S or A639S? Check your wiper arm connector type or WhatsApp us a photo" — this turns the ambiguity into another fitment-check touchpoint instead of a source of returns.
