Project 350Z- Testing the AEM Induction Cold Air Intake

by Mike Kojima

In our last trip to the dyno, we tested  AEM's Short Ram intake on our 350Z.  We were surprised to find a small but definite power increase over another leading intake that was already on the car.  Since AEM makes a long runner Cold Air Intake as well as the Short Ram, we decided to test that as well as an interesting contrast between the two vastly different intake designs.

We were expecting that the Cold Air Intake might make more bottom end and mid range power but the Short Ram would beat it out on top end.  We also noticed that on the dyno, some hot air was spilling past the heat shield and heating up the air for the motor just a little.  Would this be enough to affect power?

We started with Howard removing our front bumper fascia, first by removing the clips in front of the wheelwell
A few more fasteners and the bumper cover comes off easily.
The Short Ram intake has an integrated sampling tube for the Mass Airflow Meter built right into it.  We just took the sensor element out of the stock part and screwed it right into the intake tube.  The cold air system uses the stock airflow meter body. We bolted this machined aluminum adaptor to the airflow meter.
Next we clamped this silicone hose coupler to the throttle body.

I recently switched back over to a Short-Ram for my car for the increased intake air temps that make the computer run the engine leaner and improve MPG. To see it not lose much power is an added bonus. I think the ability to drive through puddles without worry is a pretty big bonus in my mind. Even in SoCal, I've seen my fair share of idiots stranded in the flash flood ponds that form in side gutters during some of the freak rainstorms. Driving at night in a rainstorm at full-speed without the least bit of common sense certainly seems to tax the population down here.

Mmmm JWT Popcharger it is. I'm happy with the Z's power; I just want a more aggressive sound without losing any power. Good stuff

Does AEM send you these for free? I'm jealous.

We tested the JWT POP on a G35 and it made more peak power but less in the midrange. We also tested the AEM short ram on this car. Check the Project page.

It's pretty incredible that the aftermarket is still making intakes out of metal... Auto manufacturers figured out that ABS was a better (less thermally conductive) material 20 years ago, and have slowly started making more and more intake manifolds out of it, as well.

Yeah but Aluminium is waaayy cooler man... I think the real reason is the startup cost. I'm sure it's a lot cheaper to mandrel bend and coat some aluminium than making a mold for ABS intakes for the quantities aftermarket companies deal with.

What happened to the MotorDyne intake manifold article?

@Monkius - Interesting comment that makes me wonder too. It can't be production cost can it? Or maybe the molds really are that expensive for small volume manufacturing.

I'm actually still using my 'ICEMAN' intake which is made out of some really nice ABS plastic, I believe. Adds some color to the bay, to top it off! I think they went out-of-business a while ago though...ahhh, just after the first FnF were really the days, I never thought then that all those companies wouldn't be around in ten years.

@ R33E8: The MotorDyne article will be back up before too long. It just got posted out of sequence is all.
