Bosch platinum spark plug sold individually for select Volkswagen and Audi applications. Designed for dependable ignition performance.
$16.85
The Bosch Platinum Spark Plug is sold individually and is designed to create the electrical spark required to ignite the air-fuel mixture inside each cylinder. Reliable spark delivery supports smooth engine starting, stable idle quality, efficient combustion, and responsive acceleration.
This plug uses a platinum center electrode that is heat-fused into an extended insulator. The design helps the firing end reach its self-cleaning operating temperature quickly after startup, reducing the buildup of normal combustion deposits.
Spark plugs operate under high cylinder pressure, extreme heat, and repeated ignition voltage. Over time, normal electrode wear and deposits can increase the voltage required to create a spark. When spark quality becomes inconsistent, engine performance and combustion efficiency may be affected.
Replacing spark plugs at the recommended maintenance interval supports dependable ignition performance. Servicing the full set at the same time helps maintain consistent combustion across all cylinders.
Inspect the ignition system if you notice:
Extended cranking or difficult starting.
Rough, unstable, or uneven idle.
Hesitation during acceleration.
Reduced throttle response.
Decreased fuel economy.
Engine misfires or a check-engine light.
Visible deposits, worn electrodes, or damaged ceramic insulators.
