Engineered specifically for 2006 through 2010 Chevrolet Silverado and GMC Sierra 2500HD/3500 trucks powered by the 6.6L Duramax V8 turbo diesel engine (LBZ and LMM codes), the aFe BladeRunner Turbo Inlet Manifold (Part # 46-60039-1) replaces the restrictive factory plastic turbo mouthpiece. The factory inlet features sharp internal turns and a narrow cross-section that chokes airflow into the turbocharger compressor wheel.

The aFe BladeRunner solves this bottleneck by utilizing precision-engineered Multi-Directional Vane (MDV) technology inside a large, smooth-transition cast aluminum body. This internal vane design directs and stabilizes airflow smoothly through the sharp turn into the turbo inlet, reducing turbulence and pressure drop. The manifold delivers proven gains of up to 9 horsepower and 23 lbs. x ft. of torque, lowers exhaust gas temperatures (EGTs), and improves turbo spool-up time with zero core charge.

Key Features & Benefits

• Optimized Airflow Transition: Outflows the restrictive factory plastic mouthpiece by up to 7% to maximize compressor efficiency.
• Patented Multi-Directional Vane (MDV): Internal vanes guide air smoothly around the tight turn into the turbocharger inlet, eliminating destructive turbulence.
• Proven Dyno Performance: Delivers measured increases of +9 HP and +23 lbs. x ft. of torque, along with quicker turbo spool-up and lower EGTs.
• Heavy-Duty Cast Aluminum: Constructed from robust A356-T6 aluminum and finished in a durable wrinkle-black powder coat with machined accents.
• Direct Bolt-On Compatibility: Installs using factory mounting locations and works seamlessly with both factory air boxes and aftermarket cold air intakes.
• Zero Core Charge: Brand-new outright performance upgrade requiring no core deposit or core return shipping.
