MWM Air & Exhaust

Genuine & OEM Air & Exhaust Parts

MWM Air & Exhaust Parts

The air and exhaust systems deliver clean combustion air to the cylinders and carry exhaust gas away, and restriction on either side costs power and raises operating temperature. This group covers air filters and housings, mixture and intake manifolds, charge air coolers, throttle bodies, exhaust manifolds, bellows and silencers. On gas engines the intake side carries an air and gas mixture rather than air alone, which changes the function of components between the mixer and the cylinder head. Exhaust temperatures on gas engines are typically higher and more sustained than on diesels, so manifolds, bellows and turbine housings work in a harsher thermal environment and are routine inspection points.

AMS Parts supplies a wide range of air & exhaust components for MWM engines used in power generation, marine, and industrial applications. Browse the full range below, or contact us for specific requirements.

Frequently Asked Questions

How does a gas engine intake differ from a diesel one?

Downstream of the mixer the intake carries a combustible air and gas mixture rather than air alone, which affects component specification and makes leak integrity a safety matter.

Why do gas engine exhaust components run hotter?

Gas combustion produces higher and more sustained exhaust temperatures than diesel at comparable output, working manifolds, bellows and turbine housings harder.

What causes exhaust manifold cracking?

Thermal cycling, restrained expansion and incorrect bolt torque or sequence. On gas engines the higher sustained temperatures make this a more frequent finding.
