AEM CAI Vacuum Hoses (I have two)
 

Mazda installed my aem cai and i just noticed it only has two vaccum hoses attached to it...the third inlet is capped on the intake itself. AEM instructions call for all 3 hoses to be connected...any ideas why mazda may have done this? Stock air box had 3 vacuum hose inlets as well. 2009 R3

To avoid confusion, im not talking about the VFAD nipple that isnt used anymore. Its capped. =) I am talking about the 3 inlets on the aem tube itself...one is capped and only two hoses run to it.

Huh ?

you taking about those 3 rubber hose that goes into your intake ?

Hmm, one is for venting oil air, one is for was it jet air ? the last one I forgot, I think its for emission/air pump?

Anyway, u will need to connect them all.

omp, jet air, oil filler neck

I dont remember ... :spank:

i think it's different on the 09's with the filler neck...I could be wrong, but I imagine that mazda knows to connect the omp line and the jet air hose

I think the later model cars, I believe starting in 2006 had the oil filler tube connected to the 2 nipples on the LIM.

Thread revival: Does the order of the three hoses attached matter? (top, middle, bottom)

You already see this thread?

Thanks, both. I found that thread this morning on the next page of my search from last night; just didn't get to it before giving up for the night.
