K&N 2017-2019 GM Heavy Duty 6.6L Diesel NextGen Dry Flow Cold Air Intake

K&N NextGen Cold Air Intake | 2017-2019 GM 6.6L Duramax Diesel

Boost your 2017-2019 Chevy/GMC 6.6L Duramax's horsepower and torque with the K&N NextGen Cold Air Intake. Features a DryFlow filter for oil-free maintenance.

The K&N NextGen Cold Air Intake is a premium performance upgrade designed specifically for the 6.6L Duramax diesel engine. It replaces the restrictive factory air box and intake tube with a high-density polyethylene (HDPE) induction system and an oversized DryFlow synthetic filter.

Unlike traditional performance filters, the DryFlow media requires no oiling, making maintenance simple while still providing exceptional filtration. By smoothing and straightening the airflow, this system allows your engine to breathe in more oxygen-rich air, resulting in guaranteed gains in horsepower and torque that you can feel during acceleration and heavy towing.

Best Uses

1. Heavy-Duty Towing: Improves uphill acceleration and throttle response when hauling heavy trailers or equipment.
2. Performance Enthusiasts: Ideal for owners looking for a "bolt-on" power increase without needing complex ECU tuning.
3. Off-Road & Work Trucks: Provides superior engine protection in dusty environments thanks to its state-of-the-art synthetic filter media.

Features

1. NextGen DryFlow Air Filter: High-performance synthetic media that provides high airflow and excellent engine protection without requiring filter oil.
2. Aerodynamic Intake Tube: A custom-molded HDPE tube designed to reduce air turbulence and maintain cooler intake temperatures.
3. High-Capacity Heat Shield: Helps isolate the air filter from engine heat, ensuring a consistent supply of cool, oxygen-rich air.
4. Direct Bolt-On Installation: Designed to fit into factory mounting points, allowing for a complete installation in under 90 minutes with basic hand tools.
5. Service Interval: The oversized conical filter can go up to 50,000 miles before cleaning is required under normal highway driving conditions.

Benefits

1. Increased Horsepower: Dyno-tested to provide a guaranteed increase in power and torque across the entire RPM range.
2. Improved Fuel Efficiency: By reducing engine restriction, your diesel can operate more efficiently, potentially improving MPG.
3. Aggressive Engine Sound: Enhances the natural sound of your Duramax diesel, giving it a deeper, more powerful growl under acceleration.
4. Simple Maintenance: The oil-free DryFlow filter can be quickly cleaned with water or K&N's cleaner, eliminating the risk of over-oiling sensors.
5. Lifetime Reliability: Backed by K&N’s 10-Year/Million Mile Limited Warranty, ensuring this is the last intake system your truck will ever need.
