I am a total noob at this but bought an injen CAI off another ozhonda member =] The intake came off an EM1 and i assume it was a B16A2 engine? I want to put the injen onto a D16y4.

My questions are:
- will they fit (with/without modification)
- will i need to buy an aftermarket oxygen sensor cable
- what are the two holes near the throttle body for? I know one is an oxygen sensor hole but the other one.. not sure.

ANY HELP WILL BE APPRECIATED. Thanks so much!
