can someone explain to me where to install this, and where the location is of what it replaces...im a bit lost, i know what it does and how it works, but where in the engine bay do i find this stuff.

i have a d16a6.

and how much of a gas diff does it make?

no clue about gas millage, i would assume it goes down... ummm come to a meet that i'm at and i'll explain it to you....

it takes a fairly big gash on the fuel milage...you might loose upward of 100k on a tank, depending on how you drive.... and the other thing is it doesnt really work well on reg 86 octane..you have to use 92-94 which cost more...

There is a sensor on the air intake tube, pull it out of the tube and unclip the sensor... put the sensor back into the hole to plugg up the hole.. what you are left with is a sensor clip attached to a wire leading to the wire harness... take the resistor and bend it in a u shape, then plugg it into the sensor clip, and cover it in black electrical tape to stop it from falling out...

I even taped the whole sensor clip to the sensor thats plugged back in to make it look stock, instead of having the wire and clip just hanging around in the engin bay...
