I bought my hatch with aftermarket intake installed so im not sure how the OEM was hooked up compared to the aftermarket one. I have a 98 dx but now with a d16y8 manifold. I want to install the OEM intake. On the OEM unit it has like 3 holes for sensors but on my aftermarket one all there is is a hose runing from the pipe to the nipple on the top left spot on my valve cover. Can someone provide me with some directions, id realy appreciate it.

 

bump, come on i know someone knows

 

i would normally say search, but here you go

that is the diagram and parts for a '98 dx coupe, if it's a sedan should be the same

 

But i am not using that intake. I have a dx with a d16y8 manifold and i will be installing a d16y8 OEM intake unit. There are 2 holes on the OEM unit. I have an aftermarket one right now that only has 1 hole (intake to nipple on valve cover). What is the other hole on the OEM unit used for? Do i just plug it up?

 

 

on my 00 d16y8 there is actually 3 holes
1 for iat sensor, 1 for valve cover, 1 for coolant(i think)

but on 96-98 you just have 2
1 for iat sensor and 1 for valve cover

do you not have an iat sensor no more

thats what i thought too, but barely anything if any comes from that hose into the intake arm

just look on a 99-00 ex to see what i am talking about

trust me i am not stupid (well not that stupid)

 

The 3 holes are going to be, as you said, The Air Intake Temp, One for the Valve cover breather, and the other is not coolant, but rather a "Air Assist Valve". This is only on the 99-00 Civic D16y8 equipped with "Air Injection" However, the air assist valve DOES sit on top of the Thermostat housing. (Don't break it, its $93.00 for that little plastic B*tch). Earlier Civic models do not have the Air Injection system, therefore only have 2 holes in the stock intake housing. (AIT, and Valve Breather)That is the subtraction to the system.

Hope that helps a little
