Description
Upgrade your 2011-2012 Duramax 6.6L LML with the Sinister Diesel Cold Air Intake (CAI) for enhanced performance, better fuel efficiency, and superior engine sound. Factory air intakes can’t compete with the Sinister Diesel CAI when it comes to delivering significantly improved throttle response and turbo spool-up. Whether you’re driving daily, towing, or racing, this intake system is a must-have for your Duramax engine.
This intake features CNC mandrel-bent aluminum tubing, which minimizes heat soak while providing smooth airflow and excellent durability. The oversized reusable cotton filter ensures maximum airflow and superior filtration. Finished in Signature Sinister Blue powder coating, this intake offers corrosion resistance and a bold, stylish look under your hood.
Why the Sinister Diesel Intake Stands Out
Sinister Diesel intakes combine precision engineering with superior materials to deliver unmatched performance and durability. Here’s why our intakes are the preferred choice for diesel enthusiasts:
Optimized Airflow for Peak Performance
CNC mandrel-bent aluminum tubing minimizes airflow restrictions, maximizing engine performance and efficiency.
Durable and Reliable Construction
Built from high-quality materials and powder-coated for added corrosion resistance, this intake is designed to last.
Enhanced Turbo Sound
Enjoy an aggressive and satisfying intake sound that complements your Duramax engine’s performance.
