Ignition Leads on the 2018 Suzuki Splash: Are They Used and What You Should Know

When looking into the ignition system of the 2018 Suzuki Splash, it becomes clear that traditional ignition leads are not part of this vehicle's setup. Unlike older vehicles that relied on ignition leads to carry high voltage from the ignition coil to the spark plugs, the 2018 Splash utilises a modern distributor-less ignition system.

The key reason ignition leads are not used on the 2018 Suzuki Splash is because the car features a Coil-On-Plug (COP) ignition design. This means each spark plug has its own ignition coil mounted directly on top of it. The coil fires the spark plug directly without the need to run high-voltage cables, or ignition leads, across the engine bay.

This setup has several benefits over the old system relying on ignition leads. By eliminating ignition leads, the risk of voltage loss, misfires, and interference is greatly reduced. This leads to a more reliable spark delivery and better overall engine performance. Also, the absence of ignition leads means less maintenance hassle and better durability since there are fewer parts exposed to heat, vibration, and wear.

Now, not having ignition leads doesn't mean there are no ignition components to look after on the 2018 Suzuki Splash. The coils and plugs themselves need regular attention, but because the coils sit right on top of the plugs, the system is simpler and often more reliable than one with traditional leads.

For vehicles that still use ignition leads, their purpose is pretty straightforward but absolutely critical. Ignition leads, also known as spark plug wires, carry the high voltage electricity generated by the ignition coil to the spark plugs. Without healthy ignition leads, the spark can be weak or inconsistent, causing rough running, poor fuel economy, and a lack of power.

When considering maintenance for ignition leads on vehicles that do use them, a few key points are important to keep in mind. Ignition leads can degrade over time, usually due to heat and general wear and tear. This degradation can cause the leads to crack, lose insulation, or develop internal resistance, all of which reduce their ability to deliver a strong spark.

For those who have traditional ignition leads on their car, it makes sense to check them regularly during servicing. Some signs that ignition leads might need replacing include engine misfires, rough idling, difficulty starting the engine, and even a noticeable drop in fuel efficiency. Pretty much any kind of electrical interference or poor running can be traced back to faulty ignition leads on older systems.

Replacing ignition leads is generally straightforward, but it's always best to use high-quality leads that match the vehicle's specifications. Using cheap or incorrect ignition leads can sometimes cause more harm than good by causing weak sparks or electromagnetic interference affecting other systems.

When changing ignition leads, a few practical tips come in handy:

• Replace all ignition leads at the same time rather than just the faulty ones to maintain consistent performance across the cylinders.
• Check boots and connectors for signs of wear or corrosion, as these can also affect spark delivery.
• Handle leads carefully to avoid damaging their insulation or connectors during removal and fitting.
• Apply dielectric grease to the inside of the boots to help prevent moisture ingress and ease future removal.
• Refer to the vehicle's manual for the correct firing order and connecting leads to the correct plugs and coil terminals.

Since the 2018 Suzuki Splash does away with ignition leads altogether, owners can benefit from a more modern and low-maintenance ignition system. Instead of worrying about leads, the focus shifts to ensuring spark plugs and ignition coils are in good condition and replaced as recommended by Suzuki service schedules.

So if you own a 2018 Suzuki Splash, it's worth remembering that the absence of ignition leads means fewer worries about loose connections or broken wires under the bonnet. That said, keeping an eye on coil and plug health remains vital for smooth running and maximised fuel efficiency.

To wrap it up, the ignition system of the 2018 Suzuki Splash is a step ahead of older designs. It excludes traditional ignition leads in favour of coil-on-plug technology that provides a cleaner, more reliable spark with less maintenance hassle. While ignition leads have a critical role in older vehicles, Suzuki has made life easier for Splash drivers by cutting them out completely and focusing on modern ignition technology.
