I would like to say a few things here.
1) Injen has been dyno proven on dynos that it actually looses low end power.
2) Stillen intake is a safe, but a full fledge CAI and has been tested not just by the manufacture but by many people who own it. It has been proven time and time again.
3) The Injen has been known to cause problems with the car dieing and check engine lights.
Triple, please show me where this dyno you speak up.

Posted the results... Stillen & JWT uninsulated and insulated. GSedan35 also tested his modified K&N 350Z Typhoon system and posted his results.
A seach may still be able to find these threads & posts.

Each group claims their mod (A, B, C) works because the "data" supports it and the other groups dispute it......yet no one ever posts up any data to show this (dynos, real 1/4 miles). It's all heresay. It's just a bad habit that will never seem to be broken on this site because no one seeks the truth and are just too willing to trust the butt-dyno of a complete stranger.
Classic G35driver.com.....

Some do and publish the results.
Some show up late to the party and proclaim they're the G35 educational experts and anything anyone else has previously learned, tested and shared is invalid. A news flash... there are others with 8 years plus VQ experience and maybe have access to more/better information than some others.
I just broke a personal rule--some people just aren't worth 30 seconds of your time and I spent a minute on one.

As for dynos, they're a good test. People just need to be aware that VQ's can show a 3-5 whp/wtq differences throughout the powerbands on back to back runs with no changes to the car as personnally witnessed on a ton of Maximas/Altimas and a friend's 03 G35. In the wrong hands, that 3-5whp/wtq change can be incorrectly chaulked up to "mod X made 5whp/wtq more than stock!!!!". Things need to be averaged before making claims. A Stillen intake could possibly make 6 whp above 6000rpms, but it may loose 5whp from 3000-5500rpms. On paper the car has more power, but on a track it will probably be slower.
Just curious (doubt I'll get a response), how do you have 8+ years of VQ experience? The VQ was introduced to the global market in 1995 as a 2.0, 2.5, 3.0, and 3.0 turbo. In the US, we only got the VQ30 and it remained solely a Maxima engine until it was offered as a 3.5 in the Pathfinder derived trucks and then the 3rd gen Altima and 5th gen Maxima in 02. It showed up in RWD passenger cars in 03 with intro of FM platform. The only differences between the FWD VQ35 and non-REVup RWD VQ35 are the intake/exhaust manifolds, ECU programming, and the accessory layout. They're the same block, heads, cams, etc and the overall architure and flow bench characteristics are very close to the orginal 1st gen VQs. It's largely a modular engine and it makes sense because Nissan, like most companies, is hell bent on parts bin sharing. Hell, the VQ30 heads simply bolt up to 3.5 block. On the dyno, the RWD 03-04 VQ35 with the better flowing intake manifold and tubular style exhaust manifolds typically see 230whp@6200rpms on a Dynojet. The FWD VQ35 sees 215whp@5900rpms. Both hit fuel cut at 6,600 and the RWD VQs typically hold on to more power as the rpms hang above 6000rpms. In the lower rpms, the powerbands are bascially identical.
The points to this are:
A) You must have owned a Maxima if you truely do have more than 4 years VQ experience

II) What applies to the g35, can very much apply to bascially any other VQ motor.
Sect C, subpart II.a) The G35 does not possess magical powers. It's VQ35 doesn't not behave wildly different from any other VQ on the market as some would like to believe. I've data logged my G and I see nothing special happening. It looks exactly like any other VQ data I've logged. It behaves the same in the heat, cold, humid air, etc. Same goes for it's track performance. If there's anything special about the RWD VQ35 in the FM chassis over the FWD VQ35s, it's the intake and exhaust manifolds. The RWD VQ fixed plane intake manifold and tubular exhaust manifolds have better flow characteristics than the variable capacity intake manifold and cast log-style exhaust manifolds.
