NGK Iridium X Spark Plugs One Step Colder x4 - 2.0TFSI/TSIThese NGK Iridium spark plugs for the 2.0T are one step colder and pre-gapped and suitable for all mapped 2.0T engines.
These plugs run 1 heat range colder than the stock plugs. This cooler range plug prevents early detonation and provides smoother running from your modified engine by allowing more heat transfer away from the cylinder to the cylinder head resulting in lower in cylinder temperatures; highly recommended for those running more boost.
