4x Bosh 0986221063 ignition coils and NGK LZKR6B-10E plugs. Used briefly in our Hyundai i20 2010 (see photo of engine). Purchased through a garage in attempt to solve an over fueling engine warning light scan. Was later diagnosed with having a slipping timing chain so ended up scrapping the car so pulled the new parts back off as they are basically new still. The plugs are a little fouled with it running rich but a quick clean they are as new. Please check they'll fit before purchasing please.
Bosch is a brand I trust and this product looks great and feels well built. It installed perfectly and is working perfectly. There are cheaper versions from other manufacturers but this is not expensive and so far I'm very happy with it.
