New model sparks

27 October 2013  

The latest S3 and Q7 SUV Audi models feature NGKs spark plugs. The plug for the S3 has a slim M14 thread allowing for a larger layout of the engine’s cooling ducts and its long insulator design and cup-shaped terminal provide high ignition voltages. The precious metal is resistant against spark and hot gas erosion so the electrode gap remains almost unchanged over the service life of the plug. A double precious metal type plug is used on the Q7’s V6 3 litre super-charged TFSI engine.
