Vx Spark Plug Query

[Thomas1]

I've just purchased 4 Vx spark plugs from my friendly, neighbourhood Vx dealer, for my wife's Signum 2.0T, and was surprised to see that they're single ground electrode items, instead of 4 electrodes ala Bosch Super 4.

Can anyone confirm for certain that part no. 12787099 single electrode spark plugs are the correct ones for the 2.0T? Ta.

hey bud can u mail me the details of the car reg and chassis no. and ill have a look at me work in the morning.

the vauxhall plugs aint always straight forward.

the other way to tell is if u take one out of the car there should be a number stamped in the edge of the plug compair the 2 numbers and if they are the same bingo

The plugs for the 2.0T are indeed single electrode ones. I'll double check the part number in a sec....

VVT uses single electrode long reach plugs too.

I was told the 2.0T is twin electrode standard GM ones? part number 9195109

States it's a twin electrode?

[Duncan]

They're definitely single electrodes. I'll see if I can dig out the part number.

Checked what I have in just now and they are NGK PFR6T-10G, checked on the NGK site and thats right

Don't know what the GM ones are, but I suspect they are NGK ones
