Parts for your 2024 Suzuki Splash-Ignition coils

Ignition coils for the 2024 Suzuki Splash

Based on factory literature, ignition coils are fitted to petrol-powered Suzuki Splash models and are not used on the diesel variant. The Suzuki service manuals for the K10B (1.0L) and K12B (1.2L) petrol engines specify a coil-on-plug (COP) ignition system, with one pencil-style coil per cylinder. Suzuki’s electronic parts catalogues for Splash/Agila list individual ignition coils for these engines. By contrast, the 1.3 DDiS diesel (Fiat Multijet) described in OEM workshop documentation uses compression ignition with glow plugs rather than spark plugs, so no ignition coils are fitted.

For petrol 2024 Suzuki Splash owners (including ongoing-registered vehicles), ignition coils do an unsung but vital job. They take the 12V from the battery/alternator and step it up to tens of thousands of volts, firing the spark plugs right when the engine control unit calls for it. With coil-on-plug layout, each cylinder gets its own coil, which improves spark energy and reliability, and keeps leads short so there’s less electrical loss.

They’re not a scheduled replacement item, but they do wear from heat cycling, vibration and moisture. Typical warning signs include a rough idle, sluggish take-off, higher fuel use, a flashing check engine light under load, or OBD2 codes like P0300–P0304. A quick driveway check is to swap the suspect coil to another cylinder and see if the misfire code follows it. If one coil’s failed on a high‑kilometre Splash, many workshops will fit a quality replacement to the bad cylinder and inspect the others, replacing the full set can be smart if the rest are the same age and symptoms are recurring.

Good servicing habits help coils live longer:

• Change spark plugs on time (typically 60,000–100,000 km depending on plug type). A worn plug raises coil workload.
• Keep water and engine degreaser away from coil tops and connectors. Moisture causes tracking and corrosion.
• When refitting, seat coils fully, apply a dab of dielectric grease to the boot, and tighten hold‑down bolts to spec (usually around hand-tight plus a nip, check the workshop manual for exact torque).
• Fix oil leaks into the plug tubes promptly—oil weakens boots and insulators.

Using decent aftermarket or genuine coils and scanning for codes after installation helps ensure a smooth idle and crisp throttle response. For diesel Splash owners (1.3 DDiS), there are no ignition coils to service, attention instead goes to glow plugs and the fuel system.

Popular questions about 2024 Suzuki Splash ignition coils

How can someone tell if a Splash ignition coil is failing?
Common clues are a rough idle, stumble under load, poor fuel economy and a check engine light with a cylinder‑specific misfire code. If moving the coil to another cylinder makes the misfire follow, the coil is the likely culprit. Inspect the boot for cracking and the connector for greenish corrosion.

Should ignition coils be replaced as a full set?
It’s fine to replace a single failed coil on a lower‑kilometre car. On higher‑kilometre Splash models where coils are the same age, replacing the set can prevent repeat visits. Always pair new coils with healthy plugs and check plug gaps and tube seals.

Do diesel Splash models have ignition coils?
No. The 1.3 DDiS diesel uses compression ignition with glow plugs. There are no spark plugs or ignition coils on that engine.
