On AP2, the ambient air temperature sensor is behind the heat exchanger, which affects the temperature gauge on the dashboard, but the included "for cars [AP1]" bracket is more than sufficient. to move the sensor to the side. Yes, the cable for the sensor is long enough. In addition, the horn bracket is painted and therefore insulated, which prevents the horn circuit from shorting out. Sand or file the ends of the bracket and sand between the heat exchanger bracket and the frame bracket and you should be golden. Finally, getting the K&N FIPK Heat Shield Clean Lines is a bit tricky, but easy enough. The .Mishimoto Youtube channel has a wonderful and extremely helpful video guide on how to install it. Search "Mishimoto S2000 Oil Cooler" and it was the first result at the time of publication. In terms of performance, I saw a drop in coolant temperature of about 20°F (with Mishimoto 200°F thermostat) on my OBDII dashboard display. Does exactly what I was looking for.
