K&N 77-3077KP Engine Cold Air Intake Performance Kit

Performance Intake Kit Overview

The K&N 77-3077KP is a performance air intake system built for select Chevrolet Silverado HD and GMC Sierra HD trucks. It uses a mandrel-bent aluminum intake tube and a washable, reusable oiled cotton filter to improve airflow while maintaining street-legal status in all 50 states.

Key Features

• Polished aluminum intake tube for smoother airflow and a clean engine bay appearance
• Washable cotton gauze filter with pre-oiled media
• Oversized conical filter design for extended service intervals under normal highway driving
• CARB EO D-269-49 for approved applications
• Mass air flow sensor adapter included when required
• Mounting hardware included

Detailed Description

Part number 77-3077KP is part of K&N’s 77 Series Kits, a metal intake kit line engineered for truck and SUV applications. This system replaces the factory intake path with a polished aluminum tube and a high-flow filter assembly, and it is listed as street legal in all U.S. states for the specified applications. For buyers searching for a Chevrolet Silverado 2500 HD cold air intake or a GMC Sierra 3500 HD performance intake, this kit is built around airflow, serviceability, and emissions compliance.

The reusable filter uses cotton gauze media and is designed to be cleaned and re-oiled rather than replaced at every service interval. K&N rates this system at an estimated 12 horsepower gain at 2850 RPM, and the included CARB EO number supports California-compliant applications where listed. Part number 77-3077KP also cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Reducing intake restriction in a factory-style replacement intake path
• Improving throttle response and airflow delivery
• Replacing a restrictive stock air intake assembly
• Supporting serviceable filtration with a washable filter element
• Maintaining emissions compliance on listed applications
