the 'black' ones have been discontinued for about 2yrs now!! the 'blue' version is supplied & used by Subaru worldwide now..........

we have supplied/fitted hundreds if not thouasands of the 'blue' version and never had one issue but after certain "internet hype" we looked into things in more detail and from the info garnered it would appear to be a recycling issue which is the reason behind the change in construction.......we also carried out a straw pole of other tuners/specialists and most also used these including RCM without issue

as for the American BigMac reject opening one in his car and claiming its unsupported, etc. then of course it is as its not designed to be a free standing element.........most modern cars/motorcycles use a paper element these days also
