Maximized Airflow for Performance Gains – Oversized, precision mandrel–bent 6061 aluminum tubing increases diameter and smooths airflow, delivering quicker turbo spool and a noticeable boost in power. Race-Grade TIG-Welded Construction – Fully TIG-welded bends and CNC-machined billet-aluminum flanges provide a rock-solid seal that withstands higher boost levels without leakage. Direct Fit for 1998.5–2002 5.9L Cummins – Engineered as a drop-in replacement for Dodge Ram trucks, it installs easily with the included hardware—no cutting or adapters needed. Corrosion-Resistant Powder-Coat Finish – High-gloss blue coating not only looks sharp under the hood but also protects the aluminum from corrosion and engine-bay contaminants. Proven Quality & Reliability – Pressure-tested at Sinister Diesel’s California headquarters to ensure leak-free performance and consistent boost handling under all driving conditions.
