Got some prices off them for the intercooler only. would be in US dollars.
'thick one is 2.25" and runs $799 for plates, core, bolts and gaskets.
thin one is $349 for same as above and is 1" thick.'
By the time you land them in Australia, they arn't cheap.
Looking at the thin ones size, I recon it would be next to useless, I feel the core should be bigger than the supercharger so there would be less pressure drop through it and also, I just don't think 1' would be thick enough.
The bigger one would be better. Still untill we see some data, I am only speculating.
