Automaker BMW has expanded on the practice of using nylon for the air-intake manifold by including a nylon air-filter housing and engine cover, creating an all-plastic air-intake manifold module. The module appears on BMW’s 1999, 2-litre turbo diesel engine. All components are injection molded of BASF Ultramid nylon resin.

In the past, BMW has used plastic manifolds manufactured by lost core molding. This is the first time the company has used standard molding and vibration welding. According to BASF, this technique yields significant cost savings compared with lost-core molding.

The air-intake manifold is manufactured of Ultramid A3HG7-BlackQ17 20560, a nylon 6/6 commonly used to mold manifolds. The air-filter housing cover is molded of Ultramid B3GM24, a nylon 6 containing 10 percent glass fibre and 20 percent mineral filler. The material provides good dimensional stability at high temperatures, good impact strength and good surface quality.
