After successfully installing the Injen intake today... I can honestly state that when installed specifically on a a/c 3.5 SE, it causes only the most minor and barely noticeable change in sound. Basically the volume of the engine is the same and there is no 'growl' which many people have mentioned. Not even close to the sound of a G35. not close whatsoever.

Now I don't mean to be a buzzkill, but this is the honest truth. I've read so many posts and questioned several times myself how the intake would sound, and everyone is saying it will sound awesome and close to a g35. It doesn't. I don't know if people are just describing the 'new sound' to make themselves feel better for spending the $$ on the intake, or if maybe they are driving with their windows fully down and are constantly at 5000+ RPMs.

That being said, I am happy with the intake, and would purchase it again if I were to do it all over. I did notice a slight and very welcome increase to power... The power and acceleration of the car seems a bit more balanced and smooth now.

All those clips on youtube of the intake and the revving sound just like the stock engine, and I have pointed that out before, but it was attributed to poor camera/video quality, and that it would sound different in person. It really does not though.................

Also, when I first joined this board I made a post questioning whether an intake or exhaust will give the car a more aggressive sound, and people kept saying the intake would do so much more noticeably than the exhaust. At the time I was like HUH? I thought that exhausts is where the sound resonates louder. I guess I was right though, because any youtube clip with an exhaust does sound more louder/boomier (not necessarily a good thing), but it's just an example again that there is no sound differential when installing solely an intake.

Can anyone in perfect honesty state that their a/c 3.5 sounds different after sticking in the Injen??

You just have to listen to the engine, it frees it up a little.

If you accelerate in 2nd-5th gear you can hear the g35 humm.

What i do if i want to hear it is, upshift, rpms drop to like 2k and then gas it to 3k. The hum is VERY noticble then but its not very good for the engine as i am basically upshifting at 2.5k and dropping RPMS around 2k and then adding alot of gas to push it and make the sound.

Anyways, i do notice it but it isnt exactly the g35 sound.O well.

I do notice a sound. I just installed it a couple mins ago. I agree with Chow a little. Its not going to be exacting like the g but its close. Man does it sound nice and wot is indescribable.

Not sure how you can't notice it. Anything above 2,000 rpms and she'll hum a beautiful sound!

I have my foot in my car all the time and definitely notice a difference in sound at the higher RPM's.

I installed my Injen yesterday morning but the day before I installed the Stillen Cat-back. When I got that installed, I noticed a big difference in performance. However, the next day I installed the Injen so I really didn't have time to play around just with the exhaust. But with the two combined, You can definitely notice and hear a difference! My buddy, who sold the car to me thought it was 350Zz coming around the corner but was surprise to see me! He loves the sounds and he loves the performance gains too after I took him for a ride.

You're not serious, are you? There is a very noticeable difference over stock. It may not be as "loud" as the G, but the sound is almost identical. It sounds much, much better than stock. I really can't belive it that you actually don't notice the big difference in sound like the majority of us do?

4krpm and up there is a MAJOR sound difference. not hearing it is not normal dude

Only way to not hear it would be if you have a CVT transmission.Since it doesn't behave the same as a manual you don't hear the VERY OBVIOUS SOUND difference when you downshift . I'm telling you, when going from 6th to 3rd on the highway, you definitly hear the EXTRA added growl.

the only thing i can gather is that either you are going slightly def or you got a defective unit. none of us work for or get a commision from injen, so there's no need for everyone to lie. I think Eric was the first to install it on this forum, and he's very honest with all of his remarks. He would have mentioned it back then before all the injen mania. In the end, id 99.9% of people notice the change at higher RMS's, I think we can safely assume that it not us, its you (or your intake)

I think I can speak from experience here seeing that I have both an Altima Coupe 3.5SE CVT and a 2007 G35S model. Once I installed the Injen it made a noticable difference once the RPM's ramped up. It came close to the G35, not exactly the same but very close. When I get some time I plan to get a video of them side by side and alternate punching the accelerator so everyone can hear the difference or lack thereof. I am also planning on installing an exhaust I'm just waiting to decide on Nismo, Stillen or Borla.

I dont think intakes really break in.. And I hear a hugeee difference right above the 3k rpms. Usually that's when I shift but if I don't feel like hearing it I can shift before around 2500 when its not too noticeable. You hear the difference around 2100. Not sure how you don't. Espeically in higher gears like 3rd-6th.

Hey pcpower. Perhaps you should return the intake to injen and have them replace it for you. At least give them a chanve to rectify your problem. This is their warranty statement:

Intake Warranty

Injen Technology offers a Limited Lifetime Warranty to the original purchaser against defects in material and workmanship on all intake systems excluding the filter element. Injen Technology will replace at no charge, any intake pipe considered by Injen Technology to be defective. The warranty is void if the warranty card is not returned to Injen Technology within the first 30 days of purchase. Any and all warranty coverage is limited to the repair or replacement of the defective part only, at Injen Technology.s discretion. Proof of purchase is required. The warranty does not cover incidental or consequential damages, nor does it cover the cost of installation or removal of the defective part or its replacement.

Give it a shot, you've got nothing to loose and everything to gain!

Just installed mine yesterday. I can't belive this baby! Alright...of course it feels like its alot stronger. Thats very subjective and its doubtful you get more than a 5 hp gain but the sound just makes me crazy. I can see my mileage going all to hell with my foot on the floor for every shift. You cant tell a thing at idle or below 2k. add a bit and hey....thats a little different......get up past 3k and its whoaaa.....above 4k and OMG what the hell is under there? hmmmm can I add another?

you might wanna give it some time to settle in... at first i couldn't notice much of a difference but give it a few days and people, including myself, have definitely noticed a difference... your ecu most likely needs time to recalibrate and adequately compensate for the increase influx of air...

it's insane of you to say you can't hear any diff. even if you change to a k & n drop in your can hear a diff. any difference in air flow will change the noise your engine puts off.

Busy this week, but will try to get a youtube video sometime over the weekend,, and some pics of the engine, to make sure it's not installed incorrectly or something......................

Returning it isn't going to achieve anything. It will be the same product that he received in the first place.

To the OP. I'm scratching my head here as is everyone else. There is a noticeable change in throttle noise on acceleration.

Do you think the response is affected because I do essentially 95% city driving? Is it still noticeable in the 0 - 40 MPH range in ur experience?

if you expect to hear it while cruising then a big NO NO. You should only hear a difference above 2K. Especially on acceleration between 2000-3000. Park the car, roll down the windows, and maybe pop the hood, rev it, you'll hear

i think he was expecting a g.p. sound coming off a mustang. the throttle response is a good gain and the sound is mucho more bueno. i don't really understand how you wouldn't know/hear the difference unless you really don't or didn't have a feel for how you car was before the install.

Sounds more aggressive then stock did to me. Nothing drastic, and definitely not too loud, but I like what changes I heard. Could be in my head, but I notice it and that's all that's important to me...
