Spark plugs are critical to engine efficiency, directly affecting ignition timing, combustion quality, and overall performance. In the Mini Cooper Countryman, replacing worn plugs restores fuel economy and acceleration. Routine inspection helps drivers avoid misfires and ensure smooth ignition, making spark plugs one of the most vital service parts in any maintenance plan.

The Role of Spark Plugs in Ignition

Reliable ignition requires a properly gapped and clean spark plug. When replaced with OEM components, the engine achieves optimal combustion and consistent performance. Expect the following benefits when you replace old spark plugs:
