I was just wondering if either the stock d16 or the B16 is supposed to have an IAT sensor. The stock intake tube was not with the car when I got it, so I have no idea. I got a cai intake for a 99 civic si and it fits fine 'cept for the hole for the IAT sensor. Pretty sure theres no plugs left for it, but I just wanted to double check. Every car I've ever had has had one. Thanks for the help.
