Upgrade the intake airflow on your 2011-2016 Chevrolet or GMC 6.6L Duramax LML with the Sinister Diesel SD-INTEL-LML Intake Bridge. Designed to replace restrictive factory piping after the throttle valve and heater, this intake bridge uses larger-diameter aluminum tubing and smooth-radius bends to help reduce airflow restriction, improve turbo spool, and support increased horsepower and torque. It is engineered for a direct-fit installation while retaining factory emissions equipment.
The Sinister Diesel Intake Bridge is constructed from precision mandrel-bent 6061 aluminum tubing and fully TIG-welded to CNC-machined billet aluminum flanges. The durable Sinister Blue high-gloss powder coat provides added protection and a clean appearance, while the included blue anodized aluminum resonator block-off plate completes the installation. This combination delivers a stronger, more efficient alternative to the stock cast-aluminum intake component.
The Sinister Diesel SD-INTEL-LML fits 2011-2016 GM Duramax LML applications, including Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD models equipped with the 6.6L diesel engine. The kit includes the intake bridge, resonator block-off plate, and required installation hardware. This product is not CARB approved; verify emissions requirements and vehicle compatibility before installation.
