someone said that if i relocate the IAT sensor to a cooler spot, the ECU would have better readings and reulting in a more efficient car (where would i put that). and i want to get DC headers and does the sensor shown in the picture still attch to the aftermarket one?

 

I wouldn't even consider buying a header that doesn't allow for an oxygen sensor. Looks like that's the oxygen sensor sticking out of the middle of the header but I'm not signing myself up for more spam just to take a closer look.

And the IAT I personally wouldn't mess with. I doubt it'll make much of a difference and if Honda really wanted to they could have put it anywhere on the intake which leads me to think its there for a reason. If you want to trick you ECU into taking a false reading so be it, but its there for a reason.

 

yes DC a header has an o2 sensor bung.

the other pic shows the MAP sensor, not the IAT sensor! don't mess with the MAP and the gains from IAT relocation are not worth the trouble.
