K&N 20-23 Chevrolet Silverado 2500/3500 V8-6.6L Diesel Charge Pipe Kit

K&N 77-1011KC charge pipe kit replaces restrictive factory intercooler piping on 2020-2025 Chevrolet Silverado 2500 HD 3500 HD and GMC Sierra 2500 HD 3500 HD with 6.6L V8 diesel. Mandrel-bent aluminum tubes cut turbo air pressure loss and ramp up airflow from turbo to intercooler for noticeable power gains. Lightweight design with gunmetal gray powder coat adds engine bay style and pairs with K&N cold air intakes for more horsepower.

Key Features

  • Mandrel-Bent Aluminum Tubes: Free-flowing smooth bends replace stock plastic pipes to smooth out air turbulence and support higher boost levels
  • Pressure Loss Reduction: Engineered to drop turbo charged air restrictions for quicker spool and stronger throttle response across RPM range
  • High Airflow Design: Increases volume from turbo through intercooler delivering cooler denser air to engine for efficiency and power
  • Lightweight Gunmetal Finish: Durable powder coated aluminum weighs less than OEM while resisting corrosion and heat for long life
  • No-Hassle Lifetime Warranty: K&N backs every kit with lifetime limited warranty covering defects in materials and workmanship

Product Notes

  • Installs with basic hand tools in under an hour no cutting or permanent mods required
  • Combine with K&N cold air intake systems for compounded horsepower and torque increases
  • Ships in protective packaging to prevent shipping damage

Installation Notes

  • Professional installation recommended.
  • Disconnect battery and relieve turbo pressure before starting
  • Compatible with factory couplers and clamps no additional hardware needed

Forced Induction

Forced Induction

Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...

Turbo Inlets

Turbo Inlets

A turbo inlet pipe connects the air filter or airbox to the compressor inlet of the turbocharger, providing the unrestricted airflow path the compressor needs to spool efficiently. Upgrading from a corrugated OEM rubber inlet to a smooth-bore silicone or aluminum replacement reduces restriction and turbulence at the compressor inlet, which can improve spool response and reduce inlet restriction losses at high boost. Popular Turbo Inlet Pipe Options Popular turbo inlet pipe upgrades include smooth-bore silicone inlet hoses with integrally molded reducer sections for platforms with restrictive factory accordion inlets, mandrel-bent aluminum or stainless inlet pipes for custom air filter relocation, and larger-diameter reinforced silicone inlets for high-horsepower builds where the factory inlet diameter becomes a restriction. Popular platforms with well-supported turbo inlet upgrades include the Subaru WRX, Ford Focus ST and RS, Volkswagen GTI and Golf R, and BMW turbocharged inline-f...
