Fitment Notes

• This intake is designed specifically for GM LS-family 4.8L, 5.3L, and 6.0L V8 engines in the listed truck, SUV, and luxury SUV applications. Verify your vehicle's engine displacement and model year against the fitment list before ordering. Not all engine variants in every model year are compatible - confirm using K&N's fitment guide at knfilters.com.
• The 57-3023-1 is 50-state legal (CARB Executive Order D-269-37) and can be legally used in California and all other US states on compatible vehicles. No tune required for installation - this system is designed to work with the factory OEM engine management computer and all factory emissions controls.
• Sold as a complete kit including all components required for installation - no additional purchases required for a standard installation.
• Installation uses the vehicle's existing factory mounting points and does not require drilling, cutting, or permanent modification to the vehicle. The system can be removed and the factory air intake reinstalled if needed.

Features

• Guaranteed horsepower and torque increase - K&N guarantees this specific system produces up to +14.26 HP at 5,018 RPM and up to +15 lb-ft of torque on the covered applications, backed by K&N's published dyno testing data. The gains are delivered across the engine's full RPM range, not only at peak power, translating into improved throttle response and acceleration throughout everyday driving and towing
• Roto-molded HDPE intake tube - the high-density polyethylene tube is manufactured via rotational molding to produce a smooth, seamless interior bore that reduces turbulence and guides airflow in a straight, unobstructed path from the filter to the throttle body. The non-metallic HDPE construction insulates the intake charge from engine bay heat more effectively than aluminum tubes, helping maintain a denser, cooler air charge entering the engine
• Custom heat shield - a dedicated heat shield is included that installs directly into the space previously occupied by the factory airbox, isolating the intake filter from the elevated temperatures of the engine bay. The heat shield directs the filter toward cooler ambient air while blocking radiated heat from the engine, maintaining intake air temperature benefits throughout the full operating range of the vehicle
• Oversized conical oiled cotton gauze High-Flow Air Filter - the K&N filter uses multiple layers of oiled cotton gauze pleated between two layers of wire mesh to provide a larger filtration surface area than the factory flat-panel filter, allowing a higher volume of airflow at significantly lower restriction while maintaining effective filtration of particulates that could damage the engine
• Washable and reusable filter - unlike disposable paper factory filters that must be replaced every 15,000-30,000 miles, the K&N cotton gauze filter can be cleaned with K&N's filter care service kit and re-oiled for continued use. Under normal highway driving conditions, the filter can go up to 100,000 miles between service intervals, providing a lifetime cost benefit over repeated paper filter replacements
• OEM computer and emissions system compatibility - the intake tube is designed to accommodate the factory mass air flow (MAF) sensor in its original position, ensuring the OEM engine management system reads airflow accurately and makes appropriate fuel and ignition adjustments for the increased airflow. No ECU tune or recalibration is required
• Improved throttle response and intake sound - the reduced restriction of the K&N system allows the engine to respond more immediately to throttle inputs, and the open filter design produces a more pronounced intake induction sound under acceleration that many users find enhances the driving experience
• 50-state street legal - CARB Executive Order D-269-37 confirms this system meets California Air Resources Board standards for emissions compliance on all covered applications
• Easy installation - typically installs in 60-90 minutes using factory mounting points and common hand tools. No special tools, cutting, or drilling required

Product Description

The K&N 57-3023-1 is a 57 Series Generation II FIPK (Fuel Injection Performance Kit) cold air intake system for GM 4.8L, 5.3L, and 6.0L V8 LS-family engines in Chevrolet Silverado, Suburban, Tahoe, GMC Sierra, Yukon, and Cadillac Escalade applications from 1999 through 2007. It is a complete bolt-on kit sold as a single package including all required components. This system is 50-state legal (CARB E.O. D-269-37) and requires no ECU tune.

The 57-3023-1 replaces the factory air filter and airbox assembly with a roto-molded HDPE intake tube, oversized conical K&N cotton gauze filter, and custom heat shield - the complete intake path from filter to throttle body. The HDPE tube's smooth, seamless bore reduces turbulence and intake restriction that robs the factory system of airflow, and the non-metallic material insulates the intake charge from engine bay heat more effectively than aluminum. The heat shield installs in the factory airbox footprint, isolating the filter from engine-radiated heat while directing it toward cooler ambient air. K&N's dyno testing for this specific system confirms gains of up to +14.26 HP at 5,018 RPM and up to +15 lb-ft of torque - figures that translate into noticeably improved throttle response and acceleration throughout the RPM range, not just at peak power.

The oiled cotton gauze K&N filter is washable and reusable, serviceable up to 100,000 miles under normal driving conditions with K&N's filter care service kit. The factory MAF sensor installs into the intake tube in its original position for full OEM computer compatibility with no tune required. Installation uses factory mounting points and takes 60-90 minutes with common tools. Covered by K&N's Million Mile Limited Warranty.
