Parts for your 2022 Suzuki Splash-Ignition leads

2022 Suzuki Splash ignition leads: are they used?

Short answer: no — a 2022 Suzuki Splash doesn’t use traditional ignition leads. The Splash runs a coil-on-plug (COP) setup, where an individual pencil coil sits directly on each spark plug. That means there are no high-tension spark plug wires to route or replace.

This isn’t guesswork. Suzuki’s factory literature for the Splash/Ritz platform shows plug-top ignition coils for the K10B and K12B/K12M engines and does not list any high-tension leads. The Suzuki Electronic Parts Catalogue (EPC) for Splash (YB series) lists ignition coil assemblies (e.g., 33400-xxxxx) and spark plugs, but no “cord, spark plug” group. Aftermarket catalogues from major suppliers also specify pencil coils for these engines, confirming COP across the range.

Why no ignition leads? COP mounts the coil directly over the plug, which improves spark energy, reduces electrical losses and interference, and helps emissions and reliability. It’s neater under the bonnet and removes a common wear item — the leads themselves.

• What owners will service instead: spark plugs (at the interval in the owner’s manual, commonly 60,000–100,000 km for iridium types), the coil boots/seals, and basic ignition diagnostics if there’s a misfire.
• Typical symptoms if something’s off: rough idle, hesitation, poor fuel economy, or a check engine light with codes like P0300–P0304. Swapping the suspect coil to another cylinder is a handy driveway test.
• Good practice: keep oil and water out of the plug wells, use the correct plug spec and torque, and avoid pulling coils by the connector.

Technical sources consulted: Suzuki Splash/Ritz Workshop/Service Manuals (Ignition System sections for K10B and K12B/K12M), Suzuki Electronic Parts Catalogue for Splash YB-series (Ignition group), and recognised aftermarket parts catalogues listing plug-top ignition coils for Splash/Ritz engines. These consistently show a coil-on-plug system and no ignition leads.

FAQs

Does a 2022 Suzuki Splash have ignition leads?
No. It uses coil-on-plug ignition with a separate pencil coil on each spark plug, so there are no high-tension spark plug leads fitted from factory. This layout is documented in Suzuki service manuals and the EPC for Splash/Ritz engines.

What should be serviced instead of ignition leads on a Splash?
Focus on spark plugs, coil boots, and basic ignition health. Replace plugs at the interval in the owner’s manual (often 60,000–100,000 km for iridium). Inspect coil boots for cracking or tracking, keep plug tubes dry and clean, and scan for misfire codes if it runs rough.

How do they diagnose a misfire without leads?
Scan for codes (P030x), check plug condition and gap, and try moving a suspect coil to another cylinder to see if the misfire follows. If it does, that coil’s likely done. Also look for oil in plug wells or water ingress around the coil seals.
