When a B-Series 6-cylinder BMW starts to misfire or hesitate under load, tired coils are often the culprit. The Dinan D655-0005 ignition service kit is a plug-and-play coil upgrade that installs in place of the factory coils and produces up to 10% more energy output, which helps on stock engines and on tuned engines running higher cylinder pressure. This version uses red housings with the Dinan logo for owners who like to show off engine bay modifications.
