Sinister Diesel 2011-2015 Duramax, Intake Bridge – SD-INTEL-LML


Product Highlights:

The Sinister Diesel LML Intake Bridge replaces the restrictive stock piping on your 2011 – 2016 GM 6.6L Duramax Diesel with larger diameter CNC mandrel bent aluminum tubing that optimizes airflow after the throttle valve and heater. The increased diameter of the air path and large radius bends help decrease restriction within the intake for a noticeable increase in performance and turbo spool.

Finished within eye-catching Sinister’s high-gloss blue powder coat, the Sinister Diesel LML Duramax cold air intake bridge provides an upgrade over the stock cast aluminum.
