I've held both whoosh intercoolers in my hands and the quality is great, my v2 install fitment was perfect (though some instructions or a how-to video on the site would be great! I forgot to move the little nippley things off the stock IC before reassembling the front of the car whoops).
*personally*, I know I can sometimes get parts faster or cheaper but I want to support whoosh due to Ron's active position in the community - and when I email ron with a question, he responds pretty quickly.
Anecdotal, I know, but I ordered an intake for my Fiat Abarth that was a chinese clone of an american product; when I looked inside it there were metal flakes and bits all over the place because it was never flushed after assembly - I had to clean up the inside of an intake before use because half a teaspoon full of metal flakes were in the POST FILTER part of the intake. If you order a cheap chinese clone, you should probably flush it a few times before install.
