Issues with Police BMWs

[Mactech]

Plastic manifolds have been used for years. A 104 engine from the 90's (6cyl straight six) had one. Its more of a composite really.

Yes, in racing we were using composite inlets and plenums back in the '80s. Lighter, stronger, faster

Ah, but you did not have EGR coolers to ignite them though.
