Installation Notes and Tips

Verify the connector style, terminal count, and right-side cylinder location before installation. This NGK ignition coil uses a 3-terminal blade connection and a female connector, so matching the original electrical interface is important for proper fitment. Confirm the vehicle is equipped with a distributorless ignition system and compare the original coil position to the listed fitment for Nissan Maxima and INFINITI I30 applications.

For best results, inspect the spark plug, coil boot area, and related wiring before installing the replacement coil. If one coil has failed due to age or heat, check the remaining ignition components for wear.
