We use aluminum and ABS plastic for our vents. Good for resisting tear or puncture from tree branches, knees, ice, etc.
We changed some of our vents recently from aluminum to ABS plastic. The snow doesn't stick to them and clog it up. all forward facing clutch side vents are now ABS; exhaust side is still aluminum to prevent melting.
