Parts for your 2014 Suzuki Splash-Spark plugs

2014 Suzuki Splash spark plugs: what they do and when to change them

Technical sources show that spark plugs are used on the 2014 Suzuki Splash when it’s fitted with the petrol engines (K10B 1.0-litre or K12B 1.2-litre). The Suzuki Splash Owner’s Manual and Suzuki service data specify spark plug inspection and replacement for these petrol variants. By contrast, the 1.3 DDiS turbo‑diesel (Fiat Multijet) Splash doesn’t use spark plugs at all, it uses glow plugs because diesel engines ignite fuel by compression rather than a spark.

For owners of a petrol 2014 Splash, spark plugs are a small part that make a big difference. They create the high‑energy spark that lights the air‑fuel mix in the cylinders, helping the engine start cleanly, idle smoothly and pull well through the revs. Fresh, correctly gapped plugs help the Splash run more efficiently, keep emissions in check and can even sharpen throttle response. Leave them too long and you’ll cop rough starts, a lumpy idle, flat spots, higher fuel use and sometimes a glowing check‑engine light.

As part of routine servicing, it’s smart to stick to the interval in the owner’s manual. Many Splash trims run long‑life iridium or platinum plugs that typically last far longer than old copper types. In real‑world terms, that often means inspection around the mid‑service mark and replacement roughly every 60,000–100,000 km for long‑life plugs, or earlier if wear, fouling or misfire symptoms show up. If your Splash spends its life on short trips or sees dusty conditions, check them a bit sooner.

• Tell‑tale signs they’re due: harder cold starts, hesitation under load, poorer fuel economy, or a misfire code.
• Best practice at change time: fit plugs of the exact spec and heat range listed for your engine code, avoid mixing brands or types across cylinders.
• Install tips: work on a cool engine, clean around the coil boots before removal, thread plugs by hand first to avoid cross‑threading, and tighten to the torque spec in the Suzuki manual. Most modern plugs are nickel‑plated, so anti‑seize is usually unnecessary.
• Finish up by refitting coils carefully and logging the odometer and date so the next service is easy to plan.

Diesel Splash owners: your car won’t have spark plugs. The 1.3 DDiS uses glow plugs for cold starts, and maintenance guidance sits under diesel pre‑heating system checks rather than ignition service items.

• Service data for 1.3 DDiS (Fiat Multijet) diesel: compression‑ignition system using glow plugs, not spark plugs.

Popular questions about 2014 Suzuki Splash spark plugs

How often should the spark plugs be replaced on a 2014 Splash?
Most petrol Splash models with long‑life plugs can comfortably reach 60,000–100,000 km before replacement, provided inspections show no fouling or wear. Always follow the interval and plug spec in the owner’s manual for your engine code.

What are the symptoms of worn spark plugs on a Splash?
Common clues include harder starting, a rough idle, hesitation when accelerating, higher fuel use and, at times, a check‑engine light with a misfire code. If you notice these, get the plugs and coils checked.

Does the 1.3 DDiS diesel Splash have spark plugs?
No. The diesel Splash uses glow plugs for cold starts and relies on high compression to ignite fuel. Spark plugs are only relevant to the petrol K10B/K12B engines.
