Default What is this part?

I'm referring to the split rubber hose in the picture.

Is there a part number for this or should I just measure it and buy a replacement rubber piece?

Thanks

Secondary AIR injection. If you go to shoebox he has diagrams of it. Im sure a piece the same length will be just fine. Or you could get real crazy and remove the system and plug it. Cant remember if you need to have your pcm flashed for that. I know you do if you remove egr and air.

All the AIR pump does is inject air into the exhaust to help the cats get up to temp. Delete it if you aren't in an emission state. Will light up code.

94 is easy to tune.

I'd do what fox is saying if your state allows it, though for some reason I don't think it will light the ses light on the 94. I'm pretty sure when I did this to my 94 a few years back it didn't.

My suggestion is just buy a replacement piece of bulk hose.

Hey, thanks guys!

I do live in an emissions state, NJ. But if this AIR system can be removed and have the light tuned out I'm all ears.

As I said the AIR is just to inject air into the exhaust which causes the cats to light off sooner.
