oe fitment are NGK BUR6ET (.7mm) so personally i would get a set of those. Equivalents are Autolite APP62 (.8mm), Beru 14GH-7QTUR (.7mm), Bosch W7LTCR (.9mm) and Champion RN10VTYC4 (1mm).
if you know its not had a service for a while do the oil + filter, air filter, plugs, dizzy cap, rotor arm and leads. try euro car parts and have a look on google for discount codes just before you pay
