You don't have to bid: the buy it now price is the same as the starting bid. It will be cheaper to buy the whole kit with the intercooler from cityspeed.
Cityspeed: $2779.99 shipped with intercooler.
Dude on Honda tech: $2266 shipped plus $624.97 shipped for the intercooler. Comes out to $2890.97. That is a whole $100 more for the same thing. Good deal? I don't think so...
