Specs At A Glance

Good To Know

Q: Will this cold air intake system fit my 2003 Chevy Silverado 5.3L? A: The intake is designed for 1999-2007 Chevy and GMC trucks with the 4.8L, 5.3L, or 6.0L V8, so it should fit a 2003 Silverado 5.3L. Confirm your engine size and air box configuration before ordering.

Q: Does this intake require a tune after installation? A: A cold air intake system with heat shield typically does not require a tune to run on a stock engine. A tune can help maximize gains, and some trucks may benefit from a mass airflow sensor recalibration.

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