Air Intake Heater for 2003-2004 Chevrolet C4500 Kodiak & More - Standard Ignition DIH4

Support dependable cold-morning starts with the Standard Ignition Engine Air Intake Heater DIH4. It installs as a direct-fit replacement on many vehicles, among them the 2003-2004 Chevrolet C4500 Kodiak 6.6L, 2003-2004 Chevrolet C5500 Kodiak 6.6L and 2001-2004 Chevrolet Silverado 2500 HD 6.6L (see the "Vehicles it fits" section for the full application list). This intake-air heater warms the incoming air before it reaches the cylinders, helping the V8-6.6L engine light off and run smoothly during cold-weather starts.

• Warms intake air: heats the air entering the intake to support cold-start combustion in the engine.
• Direct-fit replacement: designed to replace the original air intake heater on the listed applications.
• Engine-specific: cataloged for the V8-6.6L, with one unit used per application.

If a failed or weak intake air heater is behind hard cold starting, rough cold running, or excessive startup smoke, this DIH4 replaces that component. Diagnose the cause before ordering, since those symptoms can have other sources. One heater is supplied per package.
