NGK 48828 Ignition Coil

NGK HEI Ignition Coil 48828 Overview

The NGK HEI Ignition Coil 48828 is built for electronic ignition systems that require a 12-volt, threaded-terminal coil with a male connector and male terminal layout. It is engineered to meet or exceed OE standards for durability and consistent ignition performance across late-model domestic and import applications.

Compatible With Toyota Corolla, Camry, Celica, MR2, T100, Tacoma, 4Runner, Paseo, and Tercel applications, as well as Geo Prizm coverage in the listed model years, this coil supports direct replacement needs where the original unit uses an HEI-style design. The NGK 48828 is also referenced by part number U1014.
