K&N NextGen Cold Air Intake for 2019–2026 V8 Trucks & SUVs (50-3110) — High-Flow Filter, No Tune

The K&N NextGen Cold Air Intake 50-3110 improves airflow and adds measurable horsepower and torque for compatible 2019–2026 Cadillac, Chevrolet, and GMC V8 trucks and SUVs without requiring an ECU tune.

This engineered intake upgrades stock breathing for 5.3L and 6.2L naturally aspirated V8s by combining a rotationally molded HDPE intake tube, an oversized conical High-Flow Lifetime Air Filter, and a NextGen hybrid airbox. Tested on a dyno, the system increases intake volume and delivers real gains while maintaining factory drivability, no permanent modifications, or complicated calibration steps. The washable, reusable oiled cotton filter reduces long-term replacement cost and the airbox design helps isolate intake air from hot engine bay temperatures.

How much performance improvement can I expect from this intake?

Dyno results for the K&N 50-3110 show meaningful gains on stock vehicles: a significant boost in airflow translates to horsepower and torque increases without a required tune. Drivers notice stronger acceleration and improved throttle response, especially during full-throttle runs.

• Measured gains: approximately +19 horsepower and +19 lb-ft torque on tested platforms.
• Airflow increase: intake volume raised by roughly 30.8% versus factory tube.
• No ECU tune needed for the stated gains on compatible stock engines.

What are the key design features that make this intake effective?

The system uses a large-diameter, CAD-optimized HDPE tube with built-in air channels to increase airspeed and flow. A NextGen hybrid airbox expands the fresh air inlet and shields the filter from heat and contaminants while the oversized conical filter provides a large filtration surface for higher flow and extended service intervals.

• Rotationally molded HDPE tube for smooth, high-volume airflow.
• Hybrid airbox with enlarged fresh air inlet to lower intake temperatures.
• Oversized, radius-entry conical filter with oiled cotton media for long service life.

How often will I need to service the filter and what maintenance is required?

The included High-Flow Lifetime Air Filter is washable and reusable, engineered to provide long intervals between services under normal highway driving. Cleaning uses K&N cleaning and oil kits or equivalent follow the manufacturer’s service instructions to restore flow and protection.

• Service interval: up to 100,000 miles between cleanings under normal highway use.
• Maintenance: remove, clean, let dry, and re-oil the cotton filter when needed.
• Filter media: oiled cotton layers for a balance of filtration and high airflow.

Will installation require special tools or modifications?

Installation is designed to be straightforward and vehicle-specific, typically completed in under an hour with basic hand tools. The system mounts using supplied hardware and replaces the factory airbox and intake tube without cutting or permanent changes to the vehicle.

• Installation time: commonly under 60 minutes for experienced DIYers.
• Tools: standard hand tools—no specialty equipment or welding required.
• Fitment: vehicle-specific engineering for a finished look and secure fit.

Who this is for: Enthusiasts and owners of 2019–2026 Cadillac Escalade, Chevrolet Silverado 1500, Suburban, Tahoe, or GMC Sierra/Yukon models with 5.3L or 6.2L V8 engines who want a reliable, bolt-on performance increase without an ECU retune. It suits drivers seeking improved throttle response, a deeper intake sound under acceleration, and lower recurring filter costs thanks to a washable lifetime filter. Mechanics and DIY installers will appreciate the vehicle-specific fitment, factory-like finish under the hood, and relatively quick installation process.
