in my opinion the plastic intake manifold is the main reason for hearing the noises of the otto cycle at work, if it was a solid cast piece it would be a much quieter engine.

Hey, Plastic is Fantastic. less heat soak, smooth and dimensionally accurate runner cross section. This is an all AL motor - they are a bit noisier. The change to MOTUL 8100 eco-nergy AECA A5 made ALL the difference in the world. You will stop worrying about oil after using this stuff ( in the vinter). It is very superior on the road.
