Detailed Product Description

Delphi GN10439 is an ignition coil for coil-on-plug applications on select Suzuki Grand Vitara and Suzuki SX4 models. As a coil-on-plug unit, it mounts directly at the spark plug location to deliver high-voltage output where the ignition system needs it most. Delphi builds this part using OE experience developed through long-term supplier relationships with major automakers, bringing factory-style fit and function to the aftermarket.
