On a BMW V8 M62 from the mid 90s, is the BLACK INTAKE MANIFOLD made from Aluminum or Plastic?
More then likely it is something similar to RDX since it leaves no smoke trail a solid rocket fuel made from ammonium perchlorate, synthetic rubber and aluminum powder would leave a huge white trail behindRDX is less powerful, but is more easily concealed when fired.
Use any jackknife or Safety Stanley utility knife and srape a surfaceIf it's plastic all you'll see is black comming off If it's black painted aluminum you will see ut immediatelyI'm 99% sure it's a weight saving cheap black plastic that will eventually warp and leak because it does not have the same expansion and contraction rates as does aluminumYou're not alone many car engine manufactires are doing thisIt's probably easier to blow a perfect ideal smooth rounded cymetrical intake manifold than an as-cast aluminum one.
