APR 4.0 TFSI (EA824) V8 Ignition Coils for ~2013-2019 Model Year Audi and Bentley Vehicles| 01/19/2022
APR Ignition Coils are designed to be a direct plug-and-play upgrade to factory coils, and provide greater energy output, ensuring a stronger and more consistent spark. The commonplace replacement of factory ignition coils with those taken from the higher output Audi R8 is popularly believed to provide greater energy output. However, testing proves that they are no more powerful than the factory coils that are found on other engines. APR Ignition Coils increase energy output by up to 6% over stock. They are a direct upgrade or replacement, and come with a unique red housing!
