In this video I show which spark plugs to use and how to replace them on an Audi A4 B8 2.0T TFSI equipped with the CDNC engine. This engine is part of the EA888 Gen 2 family and produces 211 PS from the factory.

I explain the correct spark plug type, heat range, and gap for this engine, and then walk through the replacement process step by step. This applies to stock cars as well as lightly modified setups.
