5WK9-605 and 5WK9-608 Siemens's part # for the BMW MAF sensor 13621432356.

I am wondering if they are same.

My car is 2002 325ci (production date: 06/02). On the original MAF sensor, Siemens 5WK9-605 is printed.

Can my car use 5WK9-608???

The reason I am asking is because several websites I checked don't give okay for 5WK9-608 to be used on my car. It specifically advises 5WK9-605 model which tells me that there is some difference. The housing is identical, both are 3-pin MAF connectors.

Believe me I spent over an hour online to find the answer. I couldn't.

Are 5WK9-605 and 5WK9-608 same?

Confirmed, or at least we know it's successfully been done. Your Google-Fu needs some work! Found these in 5 minutes. Threads here and here.

Hi fanatics

As many have heard, the 2000 Hyundai Sonata 2.5 L shares the same SIEMENS VDO mass airflow sensor ( MAF ) as certain e46s. Researching the issue, there was generally a lot of skepticism, but after ordering one, it is in fact the exact same part for much, much cheaper. the Siemens catalog actually lists the same part for both cars too.

I went to the Hyundai forums, (promise i will never again lol) and asked what the equivalent of Pelican Parts , Tischer, etc (oem parts for cheaper) was for hyundai and actually got good responses leading me to http://www.fourgreen.com I ordered the part from that site with good reviews. Fast shipping and oem parts. it was $150. while bmw had them at $400 and for a more savvy buyer from autohas etc, minimum $300. I was surprised this hadn't been more formally addressed and just wanted to let people know :) now. one comment i did have is if you are ordering from this site please double check your order as they do not offer cash returns and I am guessing most of us wouldn't want store credit lol.

I have been running it on my car and definitely noticed improvement from the original. The car idles way smooth and I get much better mpg :)

The final thing I want to add, - while I am fairly confident in the list above, the main final check I suggest, is to make sure your car has the same MAF as e46 323i models. If this is the case, then it is 100% and you are good to go.

Here is the exact part i recieved from hyundai, identical in every way to the original i removed from my car:

Thanks for all that info. I really had no idea that Hyundai Sonata is using the same MAF. That's probably why I didn't hit any of those threads.
I was strictly searching for the parts # I posted above. I was given a brandnew MAF sensor to try on my car and it had the 5WK9 608 printed on it.
Just 5WK9 608 and the >PBT-GF30< which shows the type of material used for the housing. It doesn't say Siemens nor does it have any barcode as seen in the picture. And it has that aftermarket feel when you hold it in your hands.
Well, I tried the sensor today. I will share the result on another thread dedicated to it...

Hello guys, this is my first post here.

Just got a new MAF from a local store for my 2001 325i, they said it was a SIEMENS 5WK9605, instead they shipped a SIEMENS VDO 5WK9607. I called them as I wanted to get the correct part and they told me that they don't have the 9605 anymore so they shipped the 9607 as it is functionally identical. I didn't trust them so I asked to get my money back, they refused to do it......next step, pass the problem to my wife (lawyer), she will get my money back for sure.

Anyway, I get back home with the new MAF and I gave it a try, as soon as I installed I noticed that the idle was smoother than before, also my LTFT went down from +7.8 (same in both banks) to +3.1. Now I started to guess that maybe 9605 and 9607 are really the same device with different codes. Did someone already try to replace the 5WK9605 with the 5WK9607?

Update!..

Hi,

I finished the test on these two MAF sensors, and I can conclude that they are NOT the same sensors.
My advice is do NOT use the MAF ending in 608 in your car to save a few bucks if your original is ending in 605.
You may read more in the thread posted right in the above...
