My lower engine splash guard on my E420 is just about shot and I was thinking about permanently removing it. Has anyone experienced any problems running without the guard? I know some have mentioned that it will enhance the cooling, but I was wondering if there are any major down sides to this, like the alternator getting wet when it rains. I was also wondering if it was designed to enhance air flow and cooling, like some of the lower cowlings on other vehicles. Thanks.
