The factory valve covers are made of Magnesium and although it makes them light, it makes them prone to failure. They can't stand the sustained heat and overtime they warp leading to oil leaks. Replace them with an Aluminum over that won't warp.
Aluminum is not microporous and will not oxidize or corrode.
Aluminum is a proven material for valve covers used by many manufactures across many different models for decades. In fact, the BMW S85 V10 valve covers are aluminum. (And do not leak)
1:1 design means the NRW Design valve covers is an identical copy of the original S65 valve cover. All ancillary parts like gaskets, bolts, oil cap, cam sensors, plug tubes, oil separators, and coil packs work just like the original.
