Overview

The 4 inch cold air intake kit with heat shield is a bolt-on airflow upgrade for 1999-2007 Chevy and GMC V8 trucks.

Specs At A Glance

Good To Know

Q: Will this kit trigger a check engine light? A: Most installs run clean, but some trucks are sensitive to airflow changes at the mass airflow sensor. If a light appears, a quick ECU relearn or sensor inspection usually resolves it.

Q: Does this kit require tuning? A: No tune is required for installation, though custom tuning can help extract the most from the added airflow. It mounts using factory locations and included hardware.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
