Hi tuurio thanks for the reply which confirms excatly what I was thinking.
The question it does raise in my mind though is, why if there is no weight gain or performance gain from the all carbon airbox over the carbon / GRP airbox why does it exsist seeing as it costs $120 more is it purely the bling factor ?
There's not really a bling factor as you can't see the airbox from the outside.
If money is no problem, buy a carbon there is a slight weight gain and every gram of weight saving will count.
Maybe the carbon version is a little stronger.
But the grp/carbon is reinforced where needed with carbon layers.(around the throttlebody holes and sidewalls).
Maybe Brett can chime in and tell you the weight difference between the 2 versions.
