Got these out the box, all tips where flat, closer inspection comparing to genuine,
These plugs are much shinier than genuine, the lettering isn't central either. Search how to find if fake and these are all tell tale signs.
Also comparing the boxes the originals are cardboard where as these have green coloured card looks recycled.
Also packaging is faded blue genuine solid blue.
Had these in my high powered R26 & they've broken sending shrapnel into head.
