1990 to 2002 R129 SL Convertible Cabin Air Filter
Fits all models 300SL 500SL 600SL SL320 SL500 and SL600
In 1990 the R129 was the first Mercedes to have a cabin air filter. In fact, it may have been one of the first cars that even thought about the idea. I love cabin air filters and I find they hardly ever get changed. Located under the hood back by the firewall.
