The Spectre air intake kit for 2001–2004 GM trucks with the 6.6L V8 diesel replaces the factory intake to improve airflow and help increase horsepower and torque while protecting the engine from debris. It includes a red reusable low-restriction Spectre filter, polished aluminum tubing and a black powder-coated heat shield where applicable. Complete OE-style boots, clamps and hardware are provided and it will not void the factory warranty.
