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.

A genuinely useful, real diagnostic technique worth knowing before accepting a "replace all coils" recommendation: one documented owner was told all four coils needed replacing simply "because they fail together" — a costly blanket recommendation they successfully avoided by testing each coil individually. With the engine running and appropriate safety precautions, disconnecting each coil's connector one at a time and listening for a change in engine note identifies the specific failed coil directly.

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.

A Cheap Part That Causes Expensive-Feeling Problems

Worn spark plugs rarely announce themselves clearly — a slightly rougher idle, a bit less punch off the line — symptoms easy to blame on almost anything else in the engine bay. The part itself costs very little, which makes it an easy one to overlook for far longer than it should be.

Before you buy: plug type and gap specification vary by engine size and generation. Always confirm against your VIN before ordering.

What They Do

Spark plugs ignite the compressed fuel-air mixture inside each cylinder, and their condition directly affects combustion efficiency, fuel economy and smooth running. Petrol engines rely entirely on them; diesel engines don't use spark plugs at all, relying on compression instead.

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
