Can\'t read \'em but should be W25EBR in Denso range.
If so they\'re like NGK - fine. Got a box of 10 a few years back and no problems at all.

Yes. It\'s a long reach plug in the illustration but the part number is right. I\'ve got one of my old boxes in front of me now, W25 EBR

They\'re £7.59 each though? Stu\'s are £??

Checking on ebay Stu, those you\'ve seen are W27 EBR. I assume that\'s a different heat range (hotter? cooler?) than the plugs I\'ve used. Terrific price though for 4 plugs so worth checking with Nippon Denso what\'s the difference exactly?

loads of different type plugs,hot/standard & cold type!
W25 EBR are cold type plugs acc to haynes manual,standard are W22 EBR,hot W20EBR,so the ones on ebay W27EBR i\'m guessing are extra cold type.
 
Still a very good price for 4 triple electrode plugs but there not listed in haynes manual.
