A Genuinely Important Reason Not to Delay: Catalytic Converter Damage — Nissan Juke Spark Plugs
This is genuinely worth acting on promptly: driving with worn spark plugs or failing ignition coils doesn't just cause a rough-running engine — unburnt fuel from a genuine misfire can pass through into the catalytic converter and damage it, turning a relatively inexpensive plug or coil fault into a considerably more expensive catalytic converter replacement if left unaddressed.
It's also worth knowing that the specific cylinder number reported in a misfire fault code isn't always fully reliable — the ECU can sometimes attribute a misfire to an adjacent cylinder rather than the one genuinely at fault.
Nissan Juke Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
On the Nissan Juke, spark plug wear tends to creep in quietly — idle gets a little rougher, throttle response softens slightly — the kind of symptoms that get blamed on almost anything else under the bonnet. Given how cheap the part itself is, it's an easy one to put off for longer than makes sense.

Nissan Juke Spark Plugs: What They Do
Inside each cylinder of the Nissan Juke, spark plugs ignite the compressed fuel-air mixture, and their condition has a direct effect on combustion efficiency, fuel economy and how smoothly the engine runs. Petrol engines can't function without them; diesels don't use spark plugs, relying on compression alone to ignite fuel.
Nissan Juke Spark Plugs: Generations, Engines & Spark Plug Count
| F15 (2011–2019), petrol (1.6, 1.6 DIG-T turbo) | 4 spark plugs — the original Juke used a conventional four-cylinder engine across its petrol range |
|---|---|
| F16 (2019–present), petrol (1.0 DIG-T) | Genuinely only 3 spark plugs — the current Juke switched to a smaller turbocharged three-cylinder engine, a real change from the previous generation's four-cylinder unit; confirm your generation before ordering |
