Product Description

The K&N 57-3034 Performance Air Intake System is engineered to enhance the performance of select Chevrolet and GMC trucks equipped  Duramax LB7 engine. This system replaces the restrictive factory air intake with a high-flow, rotationally-molded HDPE tube and an oversized, conical High-Flow Air Filter™, resulting in improved engine breathing, enhanced throttle response, and a more aggressive engine sound.

Designed for easy installation, the system can typically be installed in less than 60 minutes using simple hand tools. The washable and reusable filter requires cleaning every 100,000 miles under normal highway driving conditions, offering long-term performance benefits. Backed by K&N's No-Hassle Lifetime Limited Warranty, this intake system is a reliable upgrade for those seeking increased horsepower and torque.
