Land Rover Range Rover Evoque Spark Plugs: Intervals, Fitment & Warning Signs
A genuinely useful, technical finding: this uses a wasted spark system where each coil fires two specific cylinders together, so a genuine coil failure should match a specific pairing — if it doesn't, the cause likely lies elsewhere.

Land Rover Range Rover Evoque Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
On the Land Rover Range Rover Evoque, 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.
Land Rover Range Rover Evoque Spark Plugs: What They Do
Inside each cylinder of the Land Rover Range Rover Evoque, 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.
Land Rover Range Rover Evoque Spark Plugs: Generations, Engines & Spark Plug Count
| Diesel variants (eD4, SD4, D165, D180 and similar) | Not applicable — diesel engines use compression ignition and have no spark plugs at all |
|---|---|
| Petrol variants (all Si4 Ingenium derivatives) | 4 spark plugs — one per cylinder, as this model has been offered exclusively with four-cylinder petrol engines |

A Genuinely Useful, Technical Finding Worth Knowing — Land Rover Range Rover Evoque Spark Plugs
If you're facing a misfire and trying to work out whether a coil is genuinely at fault, this is genuinely worth knowing: certain related engines use a wasted spark ignition system, where each individual coil fires two specific cylinders simultaneously, one on its compression stroke and one on its exhaust stroke, rather than each cylinder having its own dedicated coil. This means a genuine coil failure should typically produce a misfire across a specific, matching pair of cylinders together, not a single, isolated cylinder or a seemingly random combination. It's genuinely worth knowing that if your misfire codes don't match the expected cylinder pairing for a coil failure, this points away from the coil itself and toward another cause, such as a lead, sensor, or wiring issue, worth checking your specific engine's coil-to-cylinder mapping before assuming a coil is at fault.
It's also genuinely worth knowing that it's surprisingly easy to mix up wires between coils during a DIY job, and separately easy to damage a wire inside its connector while removing it — worth knowing that a wire corrected to the right position after being disturbed may have already been damaged internally, sometimes only causing a misfire to develop months later once it finally fails completely.
