Spectra Premium HVAC Heater Core

The Spectra Premium HVAC Heater Core delivers a steady source of cabin warmth by cycling coolant through its aluminum tubes to distribute heat across the interior airflow path. Its dimensions—8-9/16 by 9-5/8 inches with a 5/8-inch inlet and outlet—allow it to integrate into a wide range of HVAC housings without crowding nearby components. Its fins are arranged to promote even air spread across the entire face, reducing cold spots and supporting passenger comfort. What’s more, the inlet and outlet connections accept standard heater hoses without excessive force, streamlining installation time and helping temperature control remain stable over long drives. This Spectra Premium 99445 improves interior climate management across seasonal weather cycles.
