2001 Vauxhall Vectra 1.8 LS (Engine: Z18XE) - Engine Control Management Light - Rose27

Hi I was wondering if anyone knows the name of the following parts. I'll do my best to describe them.

There is a full unit that plugs into the fuel injectors and then there is another unit that plugs onto the spark plugs with a pronged lead that detaches from it. My mechanic has had a look at my car & run diagnostics on it but hasn't actually given me the diagnostic codes. He's just said I need two fuel injectors & the units that plug on the injectors & spark plugs (with nice little drawings of the units needed)

Anyone know there official names???

Thanks.

The unit that sits over the top of all 4 spark plugs is the coil pack (cassette).It has a multi pin connector at the gearbox end.These do give trouble and cause misfires.I very much doubt you need 2 injectors.Your mechanic is dreaming.hth
