MANN+HUMMEL is a long-standing and established development partner and series supplier for customized plastic intake manifolds for passenger car applications. Intake manifolds have the main task of evenly supplying all cylinders of an engine with air to enable an optimum combustion process. They help to reduce CO2 emissions and thus the consumption of engines. MANN+HUMMEL offers a wide range of technical solutions - from passive intake manifolds and intake manifolds with intelligent flap systems to intake manifold systems with fully integrated charge air cooling.


Passive intake manifold with fully integrated charge air cooler

Active intake manifold with robust tumble flap system

Active intake manifold for three-cylinder diesel engines

Active intake manifold with crimped charge air cooler

Passive intake manifold for four-cylinder gasoline engines
