A Genuine, Real Phenomenon Worth Understanding: LSPI on Turbo PureTech Engines — Peugeot Partner Spark Plugs
If your car has a PureTech turbocharged petrol engine and you're experiencing a knocking or misfiring sensation specifically under load at low engine speed, it's worth knowing about Low Speed Pre-Ignition (LSPI) — a genuine, industry-recognised phenomenon affecting small, turbocharged direct-injection engines generally, not something unique to Peugeot. It occurs when the fuel-air mixture ignites prematurely, before the spark plug fires, causing a knock that can potentially damage the engine over time if it happens repeatedly. Genuinely useful to know: LSPI is understood to be exacerbated by certain oil additive packages, and switching to an oil that meets the correct, current specification for this engine — combined with using a higher-octane fuel, which some owners report noticeably reduces the frequency of the knock — are the cheapest, simplest first steps worth trying.
Peugeot Partner Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
Worn spark plugs on the Peugeot Partner 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.

Peugeot Partner Spark Plugs: What They Do
The Peugeot Partner's 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.
