NGK 49632 U5543 COP Ignition Coil, Coil-on-Plug

The NGK 49632 (U5543) ignition coil is a coil-on-plug (COP) unit. It is also called a direct ignition coil or coil pack. It converts 12V battery power into the high-voltage spark that ignites the air-fuel mixture in each cylinder. NGK builds its ignition coils to OE standards for durability and dependable operation.

Key Features:

• Coil-on-plug design for a distributorless ignition system
• Standard replacement grade with a 12V rating
• Vacuum-sealed epoxy resin and thermoplastic housing for dielectric strength and voltage insulation
• Precision coil windings and laminations, plus an NGK ASIC chipset for efficient output and component protection
• Includes the ignition control module and high-temperature coil boot
• Bolt-on mount with one mounting hole
• One female connector with 4 male blade terminals
• Black color; not oil filled; no mounting bracket included

Cross-References: OE 273103L030; also listed as NGK U5543, Delphi GN10912, Standard UF863 and IC970.

A failing ignition coil can cause engine misfires, rough running, hard starting and reduced fuel economy. Replacing it restores a strong, consistent spark.
