This ASHIKA ignition coil, part number 78-0H-H15, is designed to deliver a precise electrical charge to your vehicle's spark plugs. By converting low voltage from the battery into the high voltage required for ignition, it ensures that fuel ignites effectively within the combustion chamber. A properly functioning ignition coil is vital for smooth engine operation, fuel efficiency, and reduced emissions. When an ignition coil fails, it can lead to misfires, rough idling, poor acceleration, and ultimately, a check engine light. This ASHIKA coil is manufactured to meet stringent quality standards, aiming to provide reliable performance and durability. Replacing a faulty ignition coil with this part can restore your engine's power and responsiveness.
