why are there always TWO ports on the intake pipe for smaller hoses, it's clear that the crank case vent should attach to one but what about the second one that most of us just block off?

what is it's purpose? anyone?

if no one has an answer i am probably going to put a brether on it to act as a by pass to prevent waterlocking

Intake Air Temp Sensor

Not sure what its good for....most likely has to do with A/F optimization.
Correct me if i'm wrong...i think its a OBD II+ thing.

that would make sence but i assume my car (1993 delsol with a D16 vtec) wouldn't have a temp sensor for intake air... thus plug it/cover it i guess?

yup cover it my B16a requires the breather and air intake temp sensor therefor I have 2 holes.
