The white RST on the S2 Intercooler page of the GRS site is mine. The Intercooler fitted is the original GRS Cooler. As in, the first one ever made. It is far taller than the current models, which have evolved tremendously and are not as tall, therefore causing less issue's with bonnet clearance etc.
I now have the very latest GRS version fitted and it is great.
Hope this helps.
