Silver resonator cover plate for the 2011-2016 Duramax LML
This cover replaces the intake resonator at the matching two-bolt opening on a 6.6L Duramax LML intake. The kit contains one silver-colored plate and two socket-head bolts. The plate has a solid top, rounded corners and a recessed bolt seat at each end.
Its underside has a raised circular section. That profile and the two mounting holes need to match the opening on your existing intake. The installed photo shows the cover on an intake housing; the surrounding pipework, hoses and engine components are not supplied.
Check the engine code and intake opening
The listed application is the 2011-2016 Chevrolet/GMC 6.6L Duramax LML. Check the engine code and actual intake arrangement on your Silverado or Sierra before ordering. A shared displacement or model year does not establish that the resonator opening is the same.
The gallery also lists Express and Savana vans. Those names do not confirm compatibility with an LGH engine or a different intake housing. Confirm those applications separately, as well as any aftermarket intake elbow or pipe already fitted to the vehicle.

Inspect the seal and mounting face
Compare the hole spacing, circular underside diameter and surrounding clearance with the existing intake before removing the resonator. The overall span is not a bolt-center measurement. Plate thickness, hole spacing and bolt thread size and length are not specified.
Follow the service information for your intake arrangement to check the sealing face and any required seal. Keep debris out of the opening while it is exposed, and use the appropriate fastener tightening requirement. After fitting, check that the cover seats correctly and the intake connection remains sealed. No measured horsepower, airflow or sound change is supplied for this plate.
