Pros
Unique to the AEM cold air intake system is the new dry flow technology that uses a synthetic air filter without the need for any oils. Designed to filter out 99.4 percent for contaminants as small as 1 micron, the AEM intake uses an aluminum body. As always, AEM has molded their intake filters with a built-in velocity stack, which improves the aerodynamic efficiency and shows an increase in airflow gain.
Cons
When installing the AEM MAF adapter to the factory Nissan MAF sensor, be sure to observe the sensors direction before removing and reinstalling. Installing the sensor backwards will prevent the vehicle from starting. It's not AEM's fault the 350Z's engine bay is a mechanic's worst nightmare in terms of room to work with. But the new intake does require some finagling to properly lineup with the mounting brackets and clear the A/C hardlines.

Notes
The AEM intake worked well in conjunction with the two previous products as a pickup of 7 lb-ft of torque was recorded where our previous dyno graph had shown a slight dip. A gain of 4 lb-ft of torque was shown with our peak number over the previous plenum spacer run, while horsepower showed an advantage of 3 to 5 hp with the largest margin of gain of 7hp at 5800rpm.
