A quick report about the Dinan N63 coils for my 2011 x5 50i 4.4 liter v8.
Do not purchase or install as these showed NOTICEABLY slower throttle response and decreases power output. Had to remove and reinstall old coils to get back proper performance.
In summary: the Dinan coils suck elephant balls.
