This coil pack set includes eight MSD coil packs for your 2005-2010 Mustang GT.
Features: The housing and installation are the same as the factory, but that?s where the similarity ends. Inside the MSD red housing, engineers spec?d better material to assemble the primary and secondary windings. There is also patented dual magnet technology to step up the output. Together, this combines a coil that produces higher voltage and spark energy!
They worked great until i had a miss fire and replaced the spark plugs then i kept getting check engine lights saying 6 ignition coils errors.
the only fix is to replace it at $50 each forget it. the msd's tech support was very unhelpful.
