Parts for your 2023 Suzuki Splash-Ignition coils

2023 Suzuki Splash ignition-coils — are they used, and what to know

Based on technical references, ignition coils are not relevant to a 2023 Suzuki Splash simply because that model year doesn’t exist for this vehicle. The Suzuki Splash (also sold in India as the Maruti Ritz) ended global production in the mid‑2010s — widely documented by Suzuki’s model history and independent references such as the Suzuki Splash model overview and the Maruti Ritz discontinuation notices. In other words, there is no 2023 Splash to fit ignition coils to.

For context, earlier petrol Splash variants (K10B 1.0 and K12B 1.2) used coil‑on‑plug ignition coils, as shown in mainstream parts catalogues from NGK, Denso and Delphi for 2008–2014 production. The diesel D13A/1.3 DDiS versions did not use ignition coils because diesel engines rely on compression ignition rather than spark ignition — a principle outlined in standard texts like the Bosch Automotive Handbook and diesel engine technical summaries. So, while “Splash” and “ignition coils” do go together for petrol models up to around 2014, a 2023 Splash listing isn’t applicable.

If the intent is servicing an existing petrol Splash (2008–2014), it’s a straightforward coil‑on‑plug setup. Coils aren’t a scheduled replacement item, but they do age. Tell‑tales include rough idle, misfires under load, sluggish take‑off, poor fuel economy, or a check‑engine light with misfire codes (often P0300–P0304). Swapping the coil between cylinders is a handy driveway test to see if a misfire follows the coil. Always pair coil checks with fresh plugs gapped to spec.

• Use quality coils that match the exact engine code (K10B or K12B), mixing patterns can cause fitment or connector dramas.
• When replacing, disconnect the battery, remove the engine cover, unplug the coil connector, and torque the coil hold‑down correctly to avoid cracking the housing.
• In Aussie and Kiwi conditions, coil life can be shortened by heat and moisture under the bonnet — keep the plug wells clean and the rocker cover gasket healthy to prevent oil ingress.
• If multiple coils are original and one fails at high kilometres, many workshops recommend replacing the set to restore smooth running and avoid repeat visits.

Popular questions about 2023 Suzuki Splash ignition-coils

Is there actually a 2023 Suzuki Splash, and would it have ignition coils?
No. The Splash ended production in the 2010s, so a 2023 model isn’t part of Suzuki’s line-up. If someone’s searching parts for a “2023 Splash”, they’re likely after components for an earlier petrol Splash (which does use ignition coils) or they’ve mixed up the model name.

Which Splash engines used ignition coils?
All petrol Splash engines, such as the K10B 1.0 and K12B 1.2, use coil‑on‑plug ignition coils. The diesel 1.3 DDiS (Fiat‑sourced MultiJet) doesn’t use ignition coils because it’s a compression‑ignition design.

How often should ignition coils be replaced on a petrol Splash?
There’s no fixed interval. Coils are replaced when symptoms appear or test results point to a weak unit. Many owners see well over 100,000 km, but heat, oil in plug wells, or worn plugs can shorten coil life. If one fails on a high‑kilometre car, replacing the set can save future hassles.
