Does it work like its suppose to?? that is the ultimate question, cuz if it's does what difference does it make. But just FYI, the patent on the HKS expired and now anyone can copy it and make it to HKS specs and sell it cheap and that's what's going on and why the guy is stating that it's genuine. I've seen "copies" of them out there that my buddy bought from eBay for $85 bucks shipped and we compared it to what I had at the time internally and externally looked identical and worked just as well, I kicked myself for buying mine from HKS for $240 at the time....wouldn't you do the same?
