do you buy for an SLK320?

 

I still have the original OEM Wiper Blades supplied by Valeo on my Crossfire. So I just order a replacement Wiper Blade Refill. Here are the one's I get from Amazon for the Crossfire: You can purchase the Valeo Wiper Blade Assembly complete at Amazon and I believe BatteriesPlus stores handle the Valeo product line. More an issue of how much you are willing to spend. Most Auto Part Stores carry a pretty wide product line. (Note: If you want to purchase the original Valeo Wiper Blade that has the spoiler attached to the wiper arm, you can purchase the Driver' Side for a 2003-2004 MB SLK 320, which is the same wiper blade. Don't ask me how I know this!)

I sometimes use these universal 'break to fit' wiper blade refills. I only have to shorten one of these to fit the Driver's Side. I typically change wiper blades every year and just about anyone's wiper blade will last that long.

 

I just replaced mine with Rain-X wiper blades.

 

I use RainX wipers on both of my XFire and Santa Fe and change twice a year. I have been very satisfied. Run about $15 each. Good luck.

 

I buy mine from Tirerack every five years or so...
20" Valeo Ultimate Beam Hook - driver
21" Valeo Ultimate Beam Hook - passenger

I did save the original wiper arms, just because.

 

Tried them all starting with BOSCH because they are known for quality but expensive, the original Valeo, RainEx etc.

To be honest, they are just that...windshield wipers. Not a science experiment. Went to my local Sams Club and took a look at theirs. They have them for $11 and they are fantastic. Universal fit and so far have been lasting the longest out of all of them. There is also a color indicator on them, when time to switch the blade. Check it out, they will install if you want for free.

 

Are you missing the driver's side windshield wiper grommet ? Needwings.com sells them

 

I used Otto brand they’re good and look good.
I found out on my trip to Eureka Springs and ran into 2 big rain storms.

 

BOSCH. While not the cheapest option, Bosch wiper blades are generally considered to offer a good balance of price and performance,
