I put one in my W123 diesel. I didnt really notice too much.

I put one in my brothers w124 diesel, and you notice a little bit. See with turbo cars, it doesnt really matter what kind of airfilter it is as long as its clean because the turbo will pull the air through it anyway.

You can get them from www.************************ cheaper, and sometimes they have good sales on K&N, but I dont know how it works in holland for shipping and all.

The K&Ns are a lot easier to clean and they trap more particles.
