I can just about change the plugs looking on eBay found some NGK BKR5EZ now on the special notes section it says 8valve (euro 3) any know what euro 3 means by the way I've got a sei sporting 03

Euro 3 is the emissions standard. It's the standard for your car.

Yep, those will do. Probably cheaper at Halfords with a trade card, but.........

Thank you.
