Vauxhall Vectra 2.2 SRI 2004.
I bought some Spark Plugs from VX today, fitted them and the engine sounded like a diesel (not good) Just got off the phone to VX and we established i had the wrong ones.
The ones i bought had three prongs and the ones i need have four. VX have said they will change them.
When I asked for the plugs originally I was asked what car, engine size and year. I said 2.2 2004 etc. So just for anyone looking to buy Spark Plugs from VX make sure they are aware exactly what model you have.
P.S when i phoned them to explain, they did asked for my Reg number and this is when the VX guy said (oh there are two types)
Regards
