General Spark Plugs for 57 Plate 1.2

[drumdmc]

Just about to replace the plugs on the girlfirends Panda. It's a 57 plate 1.2 Dynamic 360 limited edition.

There are Fiat ones in it just now as i took one out for a look. Usually fit NGK to my Brava so want to fit NGK to the Panda although there seem to be 2 types listed.

Anyone any idea as to what ones will be needed?

Yes, both 12mm plugs [FONT=Verdana, Arial, Helvetica, sans-serif]DCPR7E-N-10[/FONT]
and
14mm plugs [FONT=Verdana, Arial, Helvetica, sans-serif]BKR5EZ[/FONT]
are listed.

You can usually tell what plug is it by the size of the key/socket to remove them.
Methinks the 12mm plug has a 16mm (5/8's) key.
And
14mm plug has a 21mm key (13/16)

The 14mm plug BKR5EZ is for 2004 models so definitely not the ones needed.

The plug i took out had 12mm thread however the NGK website has DCPR7E-N-10 12mm from 12/04 onwards and also ZKR7A-10 from 02/06 onwards. It doesn't state a size for the latter.

1.2 Pandas up to Euro4 use the DCPR7E-N-10. My 2010 model was fitted with these in the factory.

Euro5 engines use the ZKR7A-10 (as does the 1.2 500), which has an extra 2mm projection on the electrode tip.

If you want a better quality long life plug you can also fit the NGK DCPR7EIX. I've run these for over 10k miles in a Euro4 1.2 without issues; cold starting performance is slightly better than with the standard plug. Read more on the subject in this thread.

Still confused! When did Euro 5 engines start? If your 2010 car had DCPR7E-N-10 factory fitted why does it state on the NGK site that ZKR7A-10 is from 02/06 onwards.

Would the extra 2mm projection on the ZKR7A cause any problems on a car that has the DCPR7E-N-10 plugs fitted?

IIRC late 2010.

The ZKR7A was, I believe, developed by NGK & FIAT specifically for the Euro5 1.2 FIRE. The plugs are identical apart from the projected tip. As the Euro5 engine is higher compression that the Euro4, I wouldn't have thought there'd be any clearance issues with the ZKR7A in the Euro4 engine. IIRC we debated this issue to death in the thread I referenced earlier.

What plug type is recommended in the handbook that came with your car?
