Spark plug Bosch WR11E0 (MPN 0242215801) — automotive ignition component

Bosch WR11E0 spark plug is an OEM-grade ignition component engineered for compatible petrol engines. It supplies the electrical spark required to ignite the air–fuel mixture in the combustion chamber, contributing to reliable engine starts, stable idling and efficient fuel combustion. The part is intended as a direct replacement where vehicle manufacturers specify compatible Bosch spark plugs; installation should follow the vehicle maker's torque and electrode gap recommendations.

Advantages

The spark plug is manufactured to Bosch quality standards, ensuring consistent manufacturing tolerances and electrode geometry for repeatable spark performance. Its design supports reliable ignition under a range of operating conditions and helps maintain efficient combustion, which can support predictable engine behavior and emissions control when fitted and adjusted according to vehicle specifications.

How to use

Ensure the engine is cool and the ignition system is switched off before starting. Remove the ignition coil or spark plug lead, then extract the old spark plug with a suitable socket. Inspect the cylinder and plug well for oil or debris before fitting the new spark plug. Apply the correct torque and set the spark plug gap according to the vehicle manufacturer's specifications. Reinstall the ignition coil or lead, and verify engine operation and idle quality after installation.

Recommendations

Follow vehicle manufacturer service intervals and use specified torque and gap settings. Use anti-seize or dielectric compounds only if recommended by the vehicle maker. If persistent ignition faults remain after replacement, inspect coils, leads, fuel and air systems, and engine management diagnostics.
