if you could design a w202 hood what would it look like?

ideally, please suggest things which will increase heat scavenging from the back center of the engine compartment and using vents/scoops which can be purchased online (so as to be possible to mold into an existing hood)...






otherwise- got any links to hood vents or louvers such as what i'm looking for?

got the part number for the vents used on the slk55 or similar?
