This Sinister Diesel LLY Duramax EGR Delete Kit for the 2004.5 & 2005 Chevrolet 2500 & 3500 HD takes the place of your stock EGR Valve and Cooler system. This kit fits the 6.6L LLY Duramax and provides your engine with improved exhaust gas flow, resulting in faster turbo spool and lower engine temperatures.
Our Sinister Diesel LLY Duramax EGR Delete is made in-house at our California manufacturing facility from strong nickel plated steel and machined billet aluminum then fully TIG welded and pressure tested to ensure unrivaled durability and leak-free service under the harshest conditions. The Sinister Diesel also improves engine reliability by recirculating your engine coolant faster than the stock EGR system for lower coolant temperatures, and also keeping your intake manifold free from power-robbing, hot, sooty air.
This LLY Duramax EGR Delete Kit with high flow intake has been competition tested to over 700hp making it an ideal upgrade for your high power drag or sled-pull truck.
