These are aftermarket spark plugs and ignition coils for the Nissan Serena C25/NC25. Compatible models: Nissan Serena C25/NC25 (2005/5-2010/11) with MR20DE engines. Set includes four spark plugs and four ignition coils. OEM part numbers: Spark plugs 22401-CK81B, 22401-ED815, 22401-JA01B; Ignition coils 22448-JA00C, 22448-ED000, 22448-EN200, 22448-1KT0A.
The ignition coil is an ignition device for internal combustion engines that supplies the generated current directly to the spark plug. A distinctive feature is that the distance from the ignition coil to the spark plug is short, minimizing voltage loss. This system has better combustion efficiency than mechanical systems that use a distributor, resulting in powerful torque and improved fuel economy.
Because the ignition coil works so hard to keep the car running, we recommend replacing it with a new one around 100,000 km to avoid any problems. If the ignition coil is not working properly, the following symptoms will occur:
Symptoms include hesitation during acceleration, an inability to increase rotational speed smoothly, unstable idling and stalling, and difficulty starting the engine even though there is nothing wrong with the starter motor. In a small engine compartment, the resistance of the copper wire wound inside increases over time, making it unable to generate high voltage and causing the wire to break, which is the cause of the breakdown.
If you suspect a malfunction, we recommend replacing the entire assembly with a new one. Many people choose to purchase expensive genuine manufacturer parts for replacement, but it is possible to reduce costs by using high-quality, reasonably priced aftermarket parts. Proper maintenance will make you love your car more than ever and make you want to keep driving it for a long time.
Use these spare parts for inspections and maintenance to ensure your beloved car lasts a long time. This product is a set of spark plugs and ignition coils for one vehicle, making it a great deal. While car parts supply is somewhat unstable and delivery times can be long, stocking your garage with spare parts while they're still available will give you peace of mind in case of an emergency.

The ignition coil is an ignition device for an internal combustion engine that supplies the generated electric current directly to the spark plug.
A feature of this type is that the distance from the ignition coil to the spark plug is short, minimizing voltage loss.
This system has better combustion efficiency than mechanical systems that use a distributor, provides powerful torque, and improves fuel efficiency.
They work extremely hard to keep your car running, so we recommend replacing them with new ones when the mileage reaches 100,000 km to avoid any issues.
If the ignition coil is not working properly, the following symptoms will occur:
When accelerating, the engine may stutter or not rotate smoothly, or the engine may idle unstably and stall.
Symptoms include the engine being difficult to start even though there is nothing wrong with the starter motor.
In a narrow engine room, the resistance of the copper wire wound inside increases due to deterioration over time, making it impossible to generate high voltage, and the wire breaks, which is the cause of failure.
If you suspect a malfunction, we recommend replacing the entire assembly with a new one.
Many people purchase expensive genuine manufacturer parts to replace them, but it is possible to reduce costs by using high-quality, affordable aftermarket parts.
If you maintain your car properly, you will love it more than ever and want to keep driving it for a long time.
Please use these as replacement parts for inspection and maintenance to keep your precious car running for a long time.
This product is a set of spark plugs and ignition coils for one vehicle, making it a great value.
