Volvo S60 Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
On the Volvo S60, there's rarely a clear signal when spark plugs wear out — just a rougher idle, marginally less pep off the line — vague enough to get pinned on other engine issues. Since the part costs so little, it's also one of the easiest things to keep putting off.
Volvo S60 Spark Plugs: What They Do
On the Volvo S60, combustion efficiency, fuel economy and smooth running all trace back to spark plug condition, since these are what ignite the compressed fuel-air mixture in each cylinder. Petrol engines depend on them entirely — diesels skip spark plugs altogether, igniting fuel through compression instead.
Volvo S60 Spark Plugs: Generations, Engines & Spark Plug Count
| Diesel variants (D3, D4, D5 and similar) | Not applicable — diesel engines use compression ignition and have no spark plugs at all |
|---|---|
| Older generations, petrol five-cylinder (2.4/2.5T, including S60R/V70R) | Genuinely 5 spark plugs — Volvo's distinctive inline-five, confirm generation before assuming this applies since later cars moved to four-cylinder engines only |
| Older generations, petrol six-cylinder (T6, where fitted) | 6 spark plugs — a genuinely different engine family from the five-cylinder units, not simply a bored-out version |
| Current generation, all petrol (T4, T5, T6, T8 plug-in hybrid) | 4 spark plugs — the current Drive-E engine family is four-cylinder across every trim and power output badge, regardless of how the badge number might suggest a bigger engine |

A Genuinely Easily-Made, Money-Saving Mistake Worth Knowing About — Volvo S60 Spark Plugs
If a misfire appears specifically after replacing your own spark plugs, this is genuinely worth checking before assuming the coils have failed: documented cases describe adjacent coil connectors being swapped when reconnecting them after a plug change, causing severe misfiring and multiple fault codes — with owners initially buying and fitting an entirely new set of coils that didn't fix the problem at all, only resolved by correctly matching each connector to its proper cylinder.
It's also genuinely worth knowing a useful diagnostic technique: swapping the coil from a misfiring cylinder to a different cylinder and clearing the codes can help confirm the cause — if the misfire follows the coil, it's genuinely at fault; if not, the cause lies elsewhere.
