I installed one of those knock-off intakes you get from ebay, it has the exact same bends in the tubing, and exact same filter location as the AEM intake, the only thing majorly different was the pricetag. My question to those with experience with AEM intakes is if anyone else notices a lower idle speed then usual. My z is running about 100 rpm lower then it used to, so at redlights theres just a little vibration in the shifter that is getting to be annoying. Im just checking to see if theres some problem with the intake or how it was installed, or if the low idle is a result from different filter location and filter resistance from the stock setup. Help is appreciated.

 

I got that after I installed my Nismo CAI (which is made by AEM)...

 

Same hear.....installed Nismo CAI
lower idle, but really don't see it as a problem...

 

When I go in for my oil change i'll have Nissan change the Idle a bit to composate for the CAI. See if that cures it.... Although It doesnt really bother me much... It used to when I first noticed it because I kept thinking the car was going to stall. Now im used to it and hardly notice it anymore..

 

Ditto. Got an AEM on my G.

 

Used to have an AEM CAI along w/ race cats and y pipe and had no problems at all.

 

I have the Nismo CAI, and I don't remember a change in idle RPM. Then again, I don't know that a 100 RPM change would really be that noticeable on the tach.
