Chevrolet 3500 Performance Air Intake - Sinister Diesel - Duramax LLY - Sinister Blue - '04-'05. A direct-fit cold air intake that boosts airflow and sharpens response for 2004.5-2005 GM 6.6L Duramax LLY trucks.

Designed and built by Sinister Diesel, it uses CNC mandrel-bent aluminum tubing for smooth flow and long-term strength. The Signature Sinister Blue powder coat resists corrosion, and the washable cotton filter is reusable to cut service costs. Silicone couplers and required hardware are included for a straightforward drop-in install; drivers often notice crisper throttle and quicker turbo spool-up for daily use or towing.
