Parts for your 2018 Suzuki Splash-Spark plugs

2018 Suzuki Splash spark plugs

According to Suzuki factory service information for the K10B (1.0-litre) and K12B (1.2-litre) petrol engines used in the Splash, together with NGK and Denso application catalogues and Bosch Automotive Handbook guidance on spark-ignition engines, the Splash petrol variants are fitted with spark plugs. Only the 1.3 DDiS diesel (Fiat/Suzuki D13A) uses glow plugs instead of spark plugs, as noted in Suzuki and Magneti Marelli/Fiat service literature. For most 2018-registered Splash vehicles seen in Australia and New Zealand—typically petrol imports—spark plugs are relevant and part of routine servicing.

The spark plug is the small but crucial component that lights the air–fuel mix inside the Splash’s cylinders, keeping the K10B or K12B running crisp, efficient and reliable. A healthy set helps with easy cold starts, smooth idle and clean acceleration, while also supporting good fuel economy and lower emissions. Heat-resistant ceramics, a precise electrode gap and the correct heat range allow the plug to fire consistently across town trips and open-road kilometres alike.

For servicing, owners benefit when spark plugs are inspected at regular service intervals and replaced on schedule. Iridium or platinum plugs typically last longer than standard nickel types, Suzuki service data and major plug makers suggest inspection around every 20,000 km or 12 months, with replacement often between 60,000 and 100,000 km depending on plug type, fuel quality and driving conditions. Sticking with OE-specification heat range and reach is important for the Splash’s combustion chamber design.

When replacing, technicians generally remove the engine cover, unplug the coil-on-plug units, and use a spark plug socket to extract the plugs from the alloy head. Best practice includes blowing out plug wells before removal, checking for oil or coolant traces that hint at other issues, and installing new plugs by hand first to avoid cross-threading. Modern plated plugs usually do not require anti-seize, torque should be set to the figure specified in Suzuki’s service manual to protect the aluminium threads and ensure proper heat transfer.

• Tell-tale signs it’s time: rough idle, misfires under load, sluggish take-off, increased fuel use, hard starts or a flashing check engine light.
• Good habits: use top-tier petrol, keep to the service schedule, and replace ignition coils or boots if cracked or oil-soaked to prevent repeat misfires.

Choosing quality plugs matched to the Splash’s engine code—and having them fitted correctly—keeps the little Suzuki feeling spry, economical and ready for everyday duty.

Does a 2018 Suzuki Splash have spark plugs or glow plugs?

Most 2018-registered Splash vehicles in ANZ are petrol and use spark plugs. Only the less common 1.3 DDiS diesel variant uses glow plugs. A quick check of the engine code (K10B/K12B for petrol, D13A for diesel) or the fuel type on the rego label confirms which system is fitted.

How often should spark plugs be changed on a 2018 Suzuki Splash?

With routine inspections every 20,000 km or 12 months, many Splash petrol engines run 60,000–100,000 km on long-life iridium/platinum plugs. Shorter intervals can apply with standard nickel plugs or heavy city use. Sticking to Suzuki’s schedule and using OE-spec plugs keeps starts clean and fuel use down.

What spark plug type is best for a 2018 Suzuki Splash?

OE-equivalent iridium or platinum plugs in the correct heat range and reach for the K10B or K12B engines are recommended by major plug makers and align with Suzuki service guidance. They offer strong ignition performance and longer life, which suits mixed urban and highway driving common in Australia and New Zealand.
