Wiper Blade Replacements - Bosch 3397001472 <-- don't use this
FYI ---- I decided to replace my wiper blades and elected to pay $20 some odd dollars instead of $60 some odd dollars by purchasing Bosch-branded blades as opposed to purchasing Porsche-branded blades made by Bosch. In retrospect, that was a mistake because the Bosch-braded blades are not functionally the same. Hopefully this will help someone in the future.
Nice. You can still get the wiper blades for under 50 clams if you buy from the right Porsche dealer, but geez, the rubber buffer has shot up in price since you last bought them..... They are 4x the price now.
I’ve had multiple sets of these Bosch Twin 472 blades, there’s room for the rubber widget too. Under $30 a set IIRC, bought the most recent set from FCP Euro…so the lifetime warranty applies with these now.
Also the Bosch set 472 has a 15" and a 17" blade, better to just buy the 15" & 18" on their own at half the price, and these do have the oval holes for the buffer
If you are stuck you can retain the original wiper frame and just replace the rubber blade. Just a matter of bending the end retaining clip open remove the blade and replace with new. If the blade is too long cut the rubber and use the original metal support strips.
The correct fitment for the wiper blades is with the top blade resting against the rubber bumper on the lower blade, so the wipers form an A shape. This means they will hardly be visible from the drivers seat and will not get tangled up on fast speed. Only the Bosch wipers have the correct shaped hole to accept the buffer.

Hi @Magdaddy - Really? Your Bosch 472 wiper blade sets have a provision for mounting the rubber buffer?
This Bosch set that I bought is also Bosch 472 (full number 3397001472). See picture below. And yet ---- no provision for the rubber buffer. So strange!

Thanks, right, my goal was to replace the entire blade ---- the originals are a little sandblasted after 28 years ...... gonna try to return these Bosch 472s back to eEuroparts....

Maybe yes maybe no, but I just want it to be correct.
These are what the originals look like. One blade shorter than the other and the correct shaped holes for the rubber widget (count them nine for the top one, six for the bottom). I bought a SWF set from Rosepassion recently but they were wrong so check first!
Well! I was able to return the Bosch 472s without having to pay for return shipping --- I successfully argued that the product was designed incorrectly.
I bought original Porsche branded wiper blades from the dealer --- Taiwan manufacturing for the win!

So what is the exact length of each rubber blade on the wiper you received? I am trying to verify mine.
