Had an interesting experience at the Opel dealer in Granada town here in Spain.

I would like six spark plugs for this vehicle please? Here is the Spanish log book- same details as a UK car which it was prior to export and re registration.

After a very, very long search he came back with 6 plugs and said "I think these are the ones, if they aren't bring em back!" (Most Omegas in Spain are diesels) £21 for the six.

They came in Opel boxes with a bar code 12 14 000 and on the other side 9195109 on it. The end of the box has 0 242 229 627 712 755 (09 .99) the other end has 1#9195109  GR.02.270  12 14 000

On the 10 mm plug itself it says  FLR8LDCU GERMANY 681 . They have a brass top, 4 blue bands and GM 000 in blue. They also have twin electrodes.

While I wait for my ebay flexible 10 mm spark plug socket to come from the Uk, can anyone confirm these are the right ones please?

 

Hmmmm....part code should be 91132006

So which of all those numbers is the part number then!?

If its post 08018689 engine number then its the right part number....

08226271 , Thats Ok then. One less thing to worry about.

many thanks.

GM/Vauxhall plugs are mage by Bosch.

FLR8LDCU is the correct Bosch part number for X25XE and X30XE. This is the twin-electrode plug originally fitted to the 2.5 and 3.0 engines. Vauxhall quote change at 40,000 miles / 4 years.

FGR8KQE0 is the Bosch part number for Y26SE and Y32SE. This is a four-electrode plug originally fitted to the 2.6 and 3.2 engines. It can be retro-fitted to the 2.5 and 3.0. Vauxhall quote change at 80,000 miles / 8 years.

So it would seem that the plugs you have are the correct ones for your car.

HTH.

I've had the ('wrong') 4 electrode plugs in my 99 3.0 Elite for the last years or so, if that's any help.

The 2.6/3.2 engines have modified emission control and lower compression ratio, and they will need the four-electrode spark plug and shouldn't be fitted with the older two-electrode type.

But the newer four-electrode spark plugs can be retro-fitted to earlier 2.5/3.0 engines as replacement to the original two-electrode ones.

However, the only advantage of using four-electrode spark plugs in the older 2.5/3.0 engines is the longer service life, there will be no noticeable difference is performance or fuel economy. But since I wouldn't recommend leaving the plugs in the engine for 80k anyway (I changed my four-electrode ones at 40k) - in practical terms there is no need to bother about getting four-electrode plugs for the older 2.5/3.0 engines.

Incidentally, the longer service life is the result of doubling the number of electrodes - since only one electrode actually fires at any given point of time, the theory is that the wear is halved when using a four electrode plug instead of two-electrodes...
