The Sinister Diesel intake bridge for 2011–2016 GM 6.6L Duramax LML replaces restrictive stock piping with precision mandrel-bent 6061 aluminum tubing to optimize airflow after the throttle valve. Fully TIG-welded with CNC-machined billet flanges and finished in high-gloss Sinister Blue, it reduces intake restriction and includes a blue anodized resonator block-off plate and required hardware for a complete upgrade.
