APR KT100029 Ignition Coil & Iridium Spark Plug Kit 2.5T EA855.2 5-Cylinder Blue

The APR KT100029 is a complete ignition coil and spark plug kit engineered specifically for the 2.5T EA855.2 5-cylinder engine. This blue-housing kit pairs APR's high-output ignition coils (MS100204) with APR Iridium Pro spark plugs (Z1003100) in a single, convenient package — delivering a full ignition system refresh in one box.

APR's ignition coils are a direct plug-and-play upgrade over factory units, engineered to increase spark energy output over stock for a stronger, more consistent spark. The result is a noticeable improvement in throttle response, idle smoothness, and combustion reliability — whether the vehicle is running stock or has been upgraded with higher boost and power modifications.
