Anyone know what the difference is between the 03-04 and 05-06 Nisei upper ic pipes? There are 2 models, im guessing one for non acd and one for acd cars. I'm hoping its just the support brace that is different and the pipe itself is the same on the 2 diff models.

Thanks

 

I would also venture to say it's ACD vs non ACD. Not sure of the difference though.

 

This is how I remember it as well. It's the reservoir that it needs to dodge. Can't find any pics online of it anymore to remind me though.

 

It would be the pump, not reservoir, it has to clear. The reservoir is in the corner of the engine bay, right behind the head light, the IC pipe doesn't route over there.

 

So i recently bought a pipe from a NON ACD car for my ACD car.. the difference is the support bracket on the Nisei pipe. The pipe is the same, just had to cut off the support bracket to fit my ACD car.
