Not the HT lead caps, but the nobbly bit that screws onto the threaded top of the plug. Got some Iridiumns for the MV last week, & they didn't come with the caps, which surprised me. Tried to unscrew the caps off the old plugs, except they weren't screw on ones, as I discovered when forcing them just that little bit harder & the plug fell to pieces. So I had to pop down Motorsave & buy 4 cheapo NGKs to steal the caps from. Is it normal for Iridiums not to include the caps? Looks like they do include them on all the pics I can find, & it also looks like they're the fixed type, so have I been sent fake plugs? These are what I bought - [URL]http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=380131399710[/URL]
