Parts for your 2022 Suzuki Splash-Ignition coils

2022 Suzuki Splash ignition coils — what they do and when to replace them

Yes, ignition coils are relevant and used on 2022-registered Suzuki Splash models with petrol engines (K10B 1.0 and K12B 1.2). Technical sources including the Suzuki Splash/K-Series Engine Service Manual (Ignition System section), the Suzuki Electronic Parts Catalogue for Splash (listing individual coil-on-plug units per cylinder), and aftermarket application catalogues from Denso/NGK confirm a coil-on-plug setup on these engines. Only the D13A diesel (DDiS/Multijet) variant lacks ignition coils, as compression ignition doesn’t require spark.

On petrol Splashes, each cylinder runs its own coil-on-plug unit. The job is simple but vital: step up the 12V supply to a high-voltage spark, timed precisely to light the air–fuel mix. When a coil starts to fail, you’ll usually notice a rough idle, a flat spot on take-off, poor fuel economy, or the MIL lighting up with misfire codes (often P030x or P035x). Left too long, misfires can load up the cat and shorten its life — not flash for the wallet.

Coils aren’t a routine replacement item in the Suzuki schedule, they’re replaced on condition. As part of regular servicing on a 2022 Splash, a mechanic will typically scan for misfire counts, check the coil connectors and boots, and make sure the spark plug wells are clean and dry under the bonnet. If spark plugs are due, swapping them on time helps coils live longer — tired plugs force coils to work harder. Always refit coils with clean boots, seat them fully on the plugs, and use only a light smear of suitable dielectric grease if specified in the service data. Follow the factory torque spec for the coil hold-down bolts from the Suzuki manual.

When one coil fails, many owners choose to replace just the faulty unit, others do the full set to keep things even. Either way, stick with quality parts that match the OE spec listed in the Suzuki EPC or trusted catalogues. And if the Splash is the diesel D13A, rest easy — there are no ignition coils at all, because diesel ignites the fuel by compression, not spark.

• Typical signs: rough idle, hesitation, harder cold starts, MIL on.
• Good practice: timely spark plug changes, dry plug wells, careful connector handling.
• Diagnosis: scan tool misfire data and visual inspection before replacing parts.

Popular questions about 2022 Suzuki Splash ignition coils

Does a 2022 Suzuki Splash have ignition coils?

Yes — if it’s a petrol K10B or K12B, it uses coil-on-plug ignition coils for each cylinder, as shown in Suzuki’s service manual and parts catalogue. The D13A diesel Splash doesn’t have ignition coils.

How often should the ignition coils be replaced?

There’s no fixed interval. Replace on condition: if there’s a misfire, poor performance, or related fault codes after confirming the plugs and wiring are sound. Many coils last well past 150,000 km with regular servicing.

Can a bad coil damage other components?

Prolonged misfires from a weak coil can overheat the catalytic converter and foul plugs. Sorting a coil issue promptly helps protect the exhaust and keeps fuel economy on point.
