Carbon fiber radiator cooling shroud fitted in a BMW M5 engine bay

Carbon Fiber Engine Bay

The one upgrade that changes the car with the hood up rather than down.

Radiator cooling shrouds and engine covers span the widest, most-looked-at surface in the bay, and on a stock car it is the one surface nobody finished. These are full replacements for the factory pieces, fitted to the factory mounting points, for BMW M2, M3/M4 and M5, the Ford Mustang S650 and the RAM 1500 TRX.

An engine bay is hot, bright and close quarters — this part gets looked at from eighteen inches away rather than across a parking lot, which is where surface quality actually shows.
