The visually uneven engine bay of the G8x M2/M3/M4 has been a perceived blemish Dinan has aimed to correct since delivery of our first G82 M4. At its most basic level, extending the engine cover across the charge cooler allows a more uniform and symmetrical look and provides a more complete aesthetic. Beyond the overall footprint however is a piece loaded with intriguing details. While many elements of the factory engine cover, such as the power hump, are re-used, there are numerous other features that have been enhanced or changed altogether with the Dinan offering. From vertical orientation of the cylinder count callouts to the use of opposing finishes for additional visual intrigue, the Dinan S58 engine cover stands alone in its uniqueness.
