after market bonnet scoop?

[Wizard52]

Mine isn't a.r.e but you can tell the difference, if you have a bullbar fitted chances are your scoop isn't working. blue tack some cotton and test.
Mine has vanes directing air to front as well as rear of intercooler. intercooler works at say 60kph instead of STD 80 kph

Agree with bulbar comment. With standard scoop and bulbar, front half of intercooler does not work as seen in attached photo.
