Any other Intakes other than Stillen and Injen?

Modshack:

Integral heat shield, insulated

Fresh air feeds from the fang area

But Mod .. didn't you do that yourself, or is that a kit? If it is a kit, which one is that?

JVK .. do you have any other information regarding HKS?

At this point, I am just wondering if I should go with Injen or Stillen (baring ModShacks version until he can respond) as the intakes themselves sit outside the engine box for cooler air. I am leaning more toward Injen as you do not have to modify the outlet holes to run to the front fascia, unlike Stillen. My other concern are the actual Dyno numbers on each of those kits. I "heard" that the Stillen numbers were produced with the front fascia / bumper off the car and thus the large fan placed in front of it (for the Dyno results) was able to blow clearly and easily into the Intake, whereas for Injen they actually put the front bumper back on and took a more "true to life" Dyno results. Is this true, or has anyone heard / experienced otherwise?

Thank you to everyone who has contributed to this thread, as I know you guys are much much more knowledgeable about this stuff and I truly do value your experience / opinions.

Yeah, I made it. Too labor intensive (and honestly I'm not real confident of the general DIY ability here on this forum) to offer as a kit. It is just an example of what can be done with a little imagination. Since I've custom tuned my aluminum MAF holders for a "0" fuel trim output it should dyno with the best of them though that's not what's important to me. The power under the curve is. Those that are going for the MAX dyno numbers are chasing gains you'll actually spend very little time using. Get some fresh air up there and your "in the engine bay" systems can run pretty cool with the right heat shielding. Mine runs only 6-10 degrees IAT above ambient. Similar to the one guy who posted IAT numbers on his Stillen..

Thanks Mod .. I completely understand. Very nice work by the way! I am looking for those lower numbers as well .. specifically under 3.5k RPM for that extra oompf. I was hoping that intakes similar to Stillen or Injen would help provide that lower spectrum increases.

I certainly agree with Modshack. The numbers that were just posted for the Stillen show the problem he is talking about. The intake loses power and torque from 1500 to about 3500 and really only starts to gain power above 6500. When Mike Kojima (a well-respected Nissan tuner) tested the Stillen G3 on an automatic the same problem was noted. Also, testing any intake with the hood open will skew the results one way or the other. With the hood open you are receiving air of a different temperature and getting it from a different location than you would when driving. Frankly, the only definitive idea I have taken from the intake threads is Modshack's Fang Vent which delivers the coolest air available to an intake mounted near the oem one. I have an RC2 on order and hope in combination the the MFV may provide some nice gains. However, even this might prove very difficult to test on a dyno.
