Sinister Diesel SD-INTEL-LML Intake Bridge for Chevy Duramax LML (11-15)

The Sinister Diesel SD-INTEL-LML Intake Bridge is a high-performance upgrade designed for the 2011–2016 GM 6.6L Duramax Diesel engines. Crafted from CNC mandrel bent 6061 aluminum tubing, this intake bridge replaces the restrictive stock piping to improve airflow after the throttle valve and heater. Its larger diameter and large radius bends help reduce intake restriction, resulting in increased horsepower, torque, and turbo spool. Finished with a durable high-gloss blue powder coat, it offers both enhanced performance and an eye-catching appearance. Fully TIG-welded with CNC-machined billet aluminum flanges, this component ensures a precise fit and long-lasting durability, making it an effective upgrade over the stock cast aluminum intake bridge.

Designed specifically for 2011–2016 GM Duramax LML models, this intake bridge is a direct bolt-on replacement that optimizes airflow for improved engine efficiency. It is suitable for use in street, towing, and performance applications where increased power and responsiveness are desired. The kit includes the intake bridge itself, a Sinister Diesel blue anodized aluminum resonator block-off plate, and required hardware for installation. This product is intended for enthusiasts seeking to upgrade their Duramax diesel with a high-quality, performance-enhancing component that provides better airflow and turbo response.
