| Petrol engines in this generation | See the fitment notes |
|---|---|
| Spark plugs (aftermarket) | NGK 93710 (iridium, 0.7 mm, 14 mm hex, M12x1.25, 5 kOhm suppression); Bosch 0 242 140 566 (0.7 mm, 14 mm hex, M12x1.25, 23 Nm); Champion OE277 (iridium, 0.7 mm, 14 mm hex, M12x1.25); Kamoka 7090548 (iridium, 0.7 mm, M12x1.25); Denso IK16TT (iridium, platinum earth, M14x1.25); Beru UPT12P (platinum, 0.75 mm, 16 mm hex, M14x1.25); Bosch 0 242 240 653 (0.7 mm, 16 mm hex, M14x1.25) |

| Fitment notes | The 14 mm hex M12x1.25 iridium plugs (NGK 93710, Bosch 0 242 140 566, Champion OE277) are the modern fine-wire type likely to suit the turbocharged Ingenium petrol engines, while the M14x1.25 items are older-style plugs that are probably not correct for this car; this is not tied to a specific engine by the source, so confirm before ordering; NGK 1496 is an LPG/CNG plug (60,000 km interval). |
Jaguar E-Pace Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
On the Jaguar E-Pace, 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.
Jaguar E-Pace Spark Plugs: What They Do
Inside each cylinder of the Jaguar E-Pace, 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.

| Diesel variants | Not applicable — diesel engines use compression ignition and have no spark plugs at all |
|---|---|
| Petrol variants (all trims) | 4 spark plugs — one per cylinder, as this model is offered exclusively with four-cylinder Ingenium petrol engines |

A Genuinely Useful Piece of Context Worth Knowing About Coil Pack Sensitivity — Jaguar E-Pace Spark Plugs
If a misfire appears specifically after a spark plug replacement, this is genuinely worth knowing: documented cases on related Jaguar models describe a coil pack being accidentally damaged during the plug replacement process itself, since coil packs are described as being quite sensitive to handle. It's worth having this job done carefully, worth knowing a new misfire appearing shortly after plug replacement can point to accidental coil damage during the work.
It's also genuinely worth knowing a useful diagnostic technique: swapping a suspect coil pack with the coil from a different cylinder and seeing whether the fault follows it to its new position can help confirm whether the coil itself is genuinely at fault.
