A Genuinely Overlooked Cause Worth Checking: Earth Leads — Renault Captur Spark Plugs
If you've already replaced coils, plugs, and leads without success, this is genuinely worth knowing: an experienced mechanic's account describes having to replace earth leads on numerous Renaults over the years, causing a genuinely wide range of seemingly unrelated symptoms — lights dimming, the engine not starting first time, running badly, or randomly cutting out, in addition to misfiring. A genuinely simple, practical test worth trying: temporarily attaching a jump lead directly from the engine block to the battery's negative terminal can rule earth issues in or out.
It's also worth knowing that oil seeping past the rocker cover onto the spark plug wells or coil connections, then combining with rainwater, is a genuinely common and specific cause of intermittent misfiring that worsens in wet weather — worth checking and cleaning this area thoroughly, and addressing any underlying rocker cover gasket leak.
Renault Captur Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
The Renault Captur's spark plugs rarely fail dramatically; they just quietly degrade, showing up as a rougher idle or slightly blunted acceleration that gets blamed on other things. The part costs next to nothing, which paradoxically makes it one of the most commonly neglected items under the bonnet.

Renault Captur Spark Plugs: What They Do
On the Renault Captur, the compressed fuel-air mixture in each cylinder is ignited by the spark plugs, and their condition feeds directly into combustion efficiency, fuel economy and how smoothly the engine runs. Only petrol engines use them; diesels rely on compression alone.
Renault Captur Spark Plugs: Generations, Engines & Spark Plug Count
| Diesel variants (dCi) | Not applicable — diesel engines use compression ignition and have no spark plugs at all |
|---|---|
| 0.9/1.0 TCe/SCe (standard petrol trims) | Genuinely only 3 spark plugs — this small turbocharged engine (co-developed with Nissan) is shared across Renault, Dacia and even some Smart models, not a four-cylinder |
| 1.3 TCe (higher trims, RS Line and similar) | Genuinely 4 spark plugs — this larger engine (co-developed with Mercedes-Benz) is a completely different unit from the smaller 3-cylinder TCe, despite both sharing the "TCe" badge; confirm your exact engine before ordering |
