There is a cheaper and identical one they sell.......same make etc etc for £36 as the guy found it on their system and said I could have that instead, which is what I got/paid 6 months ago.
Fitting is really easy.
Disconnect the battery and wait about 10min to discharge system, then unbolt the coil pack.
With the new coil pack near the old, transfer each lead plug to the same position (old to new).
Then bolt the new coil pack to the block where the old one was and check everything is secure.
Connect the battery and drive
