K&N 57-3070 Engine Cold Air Intake Performance Kit

Performance Intake Overview

The K&N 57-3070 cold air intake system is built for drivers who want improved airflow and a direct-fit performance upgrade. It uses a high-density polyethylene intake tube, a washable oiled cotton filter, and a heat shield to help manage underhood temperatures.

Compatible with select Cadillac Escalade, Chevrolet Silverado 1500, and GMC Sierra 1500 applications, this intake is engineered for street use where CARB-exempt fitments apply. The 57-3070 is a practical choice for owners looking for a performance intake with documented fitment and emissions-specific application notes.

Key Features

• High-density polyethylene intake tube for increased airflow volume
• Washable, reusable oiled cotton gauze air filter
• Oversized conical filter design for extended service intervals under normal highway driving
• Custom heat shield helps isolate intake air from engine bay heat
• CARB EO D-269-38/49 listed for applicable fitments
• Street legal in all U.S. states for listed applications
• Part number 57-3070 for easy identification

Detailed Description

K&N 57-3070 is a Gen II 57 Series FIPK performance intake system designed around a molded HDPE tube, a red cotton gauze filter, and application-specific hardware provisions. The system is built to increase airflow to the engine while maintaining a clean, serviceable intake path. For buyers comparing K&N intake systems for Chevrolet Silverado 1500, GMC Sierra 1500, or Cadillac Escalade applications, the 57-3070 offers a direct performance-oriented layout with fitment notes tied to CARB-exempt configurations. The part number 57-3070 is also associated with a pre-oiled filter and a replacement filter reference of RU-1042XD.

What It Helps Address

• Restricted factory intake airflow
• Heat soak from the engine bay
• Frequent disposable filter replacement
• Loss of intake efficiency from a worn or dirty filter
• Need for a documented performance intake with application-specific emissions notes

Installation Notes and Tips

Installation is typically completed in less than 90 minutes. The system includes the intake tube ports needed for the listed applications, and the mass air flow sensor adapter is included when required. Verify CARB status for your exact vehicle before installation, since emissions legality varies by application. Use the fitment notes to confirm the correct Cadillac Escalade, Chevrolet Silverado 1500, or GMC Sierra 1500 application before ordering the 57-3070.

Quality Assurance

K&N backs this intake with a 1,000,000-mile/10-year warranty. The washable filter media, reusable design, and application-specific CARB EO references support long-term serviceability and documented fitment for the listed vehicles.
