No. They are off to the side of the plastic fang panels.

See the attached pics. They are blocked from the grille area by a panel.

If you wanted direct airflow, you could open the panels and run a very short tube from the fang vent and into a hole you cut in the panel. I wouldn't direct the airflow directly at the filter because I'd still be worried about spraying water directly on the filter.

Nice write up OP. Mine have been sitting in the box at the shop since Aug. Waiting on other R&D products from shop before install. Saw the black chrome on a G37 and trying to get a swap from chrome to black. I am still considering modshacks addtional air flow mod but you make some very valid points and will prolly hold off for the time being. Thanks again.

Where do these things draw their aiflow from? The one time I've pulled my front fascia, those 'pockets' on either side where the filters sit seem to be completely enclosed. My sense is the airflow in there is pretty poor and sealed off. Am I wrong? Maybe the gains would really improve with a little ducting into those compartments.

ZForce · 01-18-2010, 12:41 PM

Re-reading through the 10 pages I found Q & A's on whether there would be a benefit on routing a hose from the fang area to the filter. And where does the air come from if the compartment of the air filter (Injen CAI filter placement) is completely sealed from outside environment.

I wanted to hilight some of the points of interest to save future readers from having to read all 10 pages.

Hope this helps!
It did for me!

Cheers

As far as pricing... PM the vendors. They can't publicly post the special pricing due to agreements with the manufacturers.

BTW, my apologies for the dirty pipes. I will clean them up tomorrow and get a pic of them clean and shiny.

I'm really glad I opted for polished over powdercoated black.

I took the front fascia off to replace the horns and those lateral areas seem very isolated from good airflow. This just puts the intake filters in their own isolated little pockets once the fascia is back on. I'd be surprised if the gains for the Ingen come anywhere close to the Stillen GenIII.

If it's really a concern, you could always remove the "dividers" and completely open that area up, but then I'd worry about getting the filters wet in rain driving. Your best bet would probably be to cut holes in the dividers and use Steve's (Modshack) technique to divert some more air into that area.

And if anyone is interested in the Modshack mod for the Injen CAI, here is the answer from Modshack and the link.

+1 Rep for doing my dirty work, ZForce. I'll have to look inside the fascia again but it sounds like air just flows in from the inboard sides of each of those 'pockets'. If I remember correctly, there wasn't much grime in those pockets when I pulled the fascia. I'd be reluctant to divert the fang vents that way and suddenly be blasting road grime all over those areas.

Damn shame (as we both have red Zs) you can't get in the same color as I got for my RSX--RED. That would have looked great in the bay !

I agree, silver is the next best choice.

+1 for the informative post !

I can't imagine what it sounds like to others as I accelerate past them... It sounds pretty wicked inside the car, especially with the windows down.

Yeah, no doubt that sound is sexy. I couldn't believe how loud it was on my RSX! Since I'm an old fart, I can easily relate to my days as a teen and being under the hood with a nice 800 CFM Holley with the air filter off listening to the butterfly open and close.

As to your comment on others hearing the sound, I remember seeing people who were busy doing things in their yard stop and look when they heard the sound of me kicking it in 1st or 2nd. Even had one guy call the cops on me for speeding (when I wasn't...the sound just SOUNDED like I was speeding) in our subdivision.

Am I missing something or did this 'm4a1' fella not post his second dyno chart?

m4a1mustang · 03-19-2010, 08:10 AM

Steve, the shop never followed through to email me the graph. I was less than impressed with their operation so I am not trying to go back and see if I can get it from them. If you want, I can draw you a graph this weekend, but honestly it looks exactly like all of the G3 and Injen charts out there. Minimal gains until 7k, where the stock airboxes fall off.
