| The intake tube in place descending into the wheelwell area. |
AEM first assembles the complete stock intake system on their flow bench and logs MAF voltage over a very wide range of air flow conditions. This gives the engineers a voltage to airflow curve as the stock intake system sees it. They then build a cold air system, tuning it for best power and powerband using resonant tuning and dyno testing. When they get what they feel is a good first iteration of the intake, they flow bench it and compare the MAF voltage curve vs the stock curve and program the ETI box to correct the modified intake voltage curve to match the stock one.

The intake then goes back to the dyno for further fine tuning and if a different configuration is found that makes more power, it goes back on the flow bench for more ETI tuning. This might go back and forth several times over the development of an intake. During testing the ECU is monitored for changes in long and short term trim on both the dyno and road testing with the goal being little drift in trim from stock.

The ETI module frees the engineer from having to compromise the design in MAF tube diameter or placement simply to keep the ECU happy so he can build a system for maximum power. So does this technology work? Will the ETI intake make drift free power on the 370Z, perhaps one of the most notorious intake hating cars on the market? We will see!

| With the filter in place you can easily see why the windshield washer reservoir had to be relocated. |
Initially we were impressed with the AEM intake kit. The intake pipes were all nicely finished aluminum. Twin dryflow air filters which have OEM spec filtration draw cold air from the area forward of the front wheels behind the front bumper fascia.

| Left side filter in place. The AEM dryflow filters are not oiled and filter to the same levels as OEM filters. |
The kit is very complete. Since the windshield washer reservoir is smack where AEM wanted to place the passenger side filter, they relocated the reservoir to the front of the car providing a custom molded low profile part complete with a pump and an adapter harness as well as a special custom molded filler neck for a very clean installation.

| AEM provides this new remote windshield washer reservoir filler for the engine compartment. |
 |
| The windshield washer pump and the relocated MAF sensors must be rewired with new harnesses provided in the kit. |

Hɑving read this I believed it was very informɑtive.
I appreciate you finding the timе and effort to put this informatiߋn together.
I once agaіn find myself spending a lot of timе both reading
and commenting. But so what, it was still worth it!
