I've got my Injen CAI in the mail 2 days ago and finished installing yesterday in SRI mode. Installation was fairly easy, thanks to all the detailed posts from forum members, thanks again The only problem I came up with, was when I pulled out the radiator tube, I got a face-load of green shit Good thang I wore my glasses.

I did a quick comparision of the Injen filter and the Monster Flow filter. My first impression on the Injen filter was, "wow, I'm going deaf... louder, louder!!!" Throttle response increased dramatically, there used to be some lag for the engine to respond, but now that lag is nearly gone. I definitely feel a lot more torque in the mid rpm range, and vtec engagement now comes with a serious "hissing" sound. Injen filter sounded a lot more brutal and louder. While Monster Flow filter sounded slightly quieter but deeper in tone, with more noticeable "hissing" (sucking air) sound. Performance wise, with Monster Flow there were more high rpm power, especially at vtec engagement, I could really feel a stronger jerk compared with Injen filter. At lower rpm, I couldn't really feel much difference, but it all changed when rpm hits 4500+. I will complete the installation by connecting the 2nd part of the injen tube to convert it into a full CAI this week and post my thoughts.

Downside to all of these is... I've gased up full tank yesterday night and now i'm down to 3/4 full... For those of you still deciding if you should get the CAI, don't hesitate, it's the best mod I've had so far!!!

I am waiting to save up enough $$ to do everything at once, and when that time comes I really dont know if I want Injen.. All i hear is how loud it is, will it take away the "luxury" appeal and transform my car into a rice burner?

 

It's not ricey like those coffee can mufflers but more like a "growl". Like everyone says, it's louder than stock but I wouldn't say it's a ricey sound. Best thing to do is take a ride with someone who's already done it but I'd have to agree that it's also my best mod so far.

 

In normal day to day driving where you don't go much above 3000-3500rpm before changing gears (unless you've got an auto) and you never open the throttle more than about 1/2 you won't notice any difference in volume whatsoever. The induction noise you hear will be deeper and richer than stock but not louder.

 

Told you that Monsterflow is a good filter =)

 

Nice to hear you're enjoying your new mod KC

 

I wouldn't call it a "rice burner" but the sound is very far away from "luxury".

I've had CAIs on a couple of my past cars. Ultimately, I decided against adding one to my TSX b/c the noise is too conspicuous. Yes. It is true that if you're light on the throttle, the extra sound is hardly noticeable.

The problem is, no one drives this way all the time. In fact, due to the TSX's relatively low amt of torque, I find myself flooring my car very frequently even when I'm not trying to go fast. With a CAI, when you do punch it, it is MUCH louder than stock. This is bad b/c I don't want to draw attention when I'm driving briskly. Sometimes, even if I wasn't driving very fast, I would reach a certain RPM and the sound would start to come on. This is bad if there is a cop next to you.

Of course, if you actually want your car to sound like mean motherfucker, then by all means, get the CAI. Buy a header and exhaust while you're at it too.

 

That's exactly what I don't want. Just like everyone else I need more speed but I want to keep it somewhat 'classy'. I guess Hondata is my best option maybe matched with some overpriced (for their gains) comptech mods.

 

3pedal, is ur intake still in SRI mode? have you notice any difference between SRI and CAI?

 

Well... the fact that you have a red car maybe draws a little more attention to your car vs. another more "muted" color.

But it's all love for your car Zgo, I love that red!

 

damnit! this thread makes me want to get one now! where is the best online deal for one?

 

how much was the new filter?

 

LOL. I thought the exact same thing as I was typing what I wrote above.

Funny thing is, I got the least amt of tickets ever in my last red car - a 300ZX TT which I used to speed in ALL the time. I had dual CAIs in that car. Thanks to the turbos, the exhaust and intake sound was very quiet. It was really no louder than a stock non-turbo Z.

 

Hondata w/ a DC Sports header would yield good gains w/o a significant increase in noise as long as you stick w/ the stock intake and exhaust. You can also add the Comptech Icebox, but the gains would be minimal compared to what an open CAI such as the AEM or K&N would provide.

 

Seconding this request. Could somebody link to a reputable source for these? Hondata reflash has led me to purchase an Injen CAI and I'd like to do this backfit.

 

Injen and K&N, AEM only makes a SRI for the TSX

 

what the hell is a monster filter?



and i thought you weren't supposed to feel a vtec jerk in i-vtec motors?!?!

 

I saw 2 used Injens on sale in Private sales section, one blue one red i believe.

Dzuy: pics coming tonight! at vtec engagement, the engine gives more "punch" (monster flow) than with the Injen filter, it's not a huge jerk, but i could feel the stronger pull

 

Alright, just finished turning my Injen SRI into CAI. Here is the picture of that Monster Flow Filter



I must say I enjoy the quick throttle response of the SRI more than the high end power of the CAI. With the CAI, you can feel slightly more punch in higher rpm, but down low, throttle is a bit retarded compared with SRI. I'm probably gonna turn it back into a SRI later this week

kc, where did you get the monster flow filter?

 

Where did you purchase that monsterflow filter?

 

bought the whole thing from a forum member. I did do a google search for Monster Flow filter, and they go for $70 apiece.

I tried something really primitive, had both injen and monster flow filters sitting side by side. then i got my hair dryer then blew air into the filter while sticking my hand inside the filter. i compared both filter and i could feel the monster flow filter having more air flow into the filter. Also, with the monster flow, air seemed to be more concentrated on the inside of the filter, while injen filter felt dispersed. Again, the Monster flow filter does not sound as loud as the Injen Filter, and that's exactly what i'm aiming for.

odd that you prefer the SRI mode. I dont think there is any actual performance help from the SRI, even the quick engine response you speak of. we just think things up. but thats cool if you like it. I was really frusterated when i went to SRI, doesnt have that harmonic from the air in the tube

 

Here is one: http://www.eautoworks.com/html/ORD-A...r-no-23598.htm

What is the OD of the Injen tubing? I think it's 3" but you'd need to make sure.

 

i hear the comptech ice box cold air intake is almost like stock when it come to sound but do u guys think it would add the same amount of power as injen?

 

No, the Icebox adds a hair over half of what an Injen or K&N CAI does. I have one and it is pretty quiet, sort of like a deeper growl, but I'm replacing it with an Injen CAI now that the Hondata reflash has shown to work well with it.

 

Injen tube diameter is 3".

I've got the chance to drive fast on the CAI today, and the high end power is significant. SRI's benefit is only throttle response, and it takes away that throttle lag on the tsx almost 99%. I will probably keep it in CAI now getting to feel what it can do at high speed, gonna also read some dynos on CAI, SRI while i'm at it.

Hope ur enjoying it =)

 

What are the actual hp numbers? what do you guys think the best CAI is for the money?? Im looking to improve hp and get a deeper growl from the engine, but i dont want something too loud. Thanks

 

10-12 HP in CAI mode
8-9 in SRI mode

Injen or K&N are the best

 

This link will provide much info:

https://acurazine.com/forums/search.php

 

Injen CAI has a slightly larger diameter than the K&N one therefore giving a bit more hp at higher rpm. Both K&N and Injen CAI can be converted into SRI mode as well. Since you dont want it to be too loud, CAI should be more suitable for you, SRI is a lot louder than the CAI.

negative. the SRI just sounds raspy, kinda raw sounding, not necessarily louder tho. the CAI just has the longer tube, so it builds harmonic tones as the air travels. but its a deep tone that the SRI can't duplicate.
The CAI is more power, and sounds 10x better, its a little more exciting to rev up.

 

hey! has anyone thought of or attempted wrapping the CAI tube body with insulation (from home depot or lowes) and see if it reduces the noise???

i'd try but don't have a CAI

 

ENJOY THE INJEN CAI. IM LOVING MINE TOO. SOUND IS AMAZING AND I DEF THINK ITS A GREAT INVESTMENT. GOOD LUCK

 

its too pretty to wrap up!

 

You all have any problems with the INJEN CAI at the dealers if you bring it to them for service?

 

Yea, i had a problem with them all wanting to try it out...


Why would they give a problem with service if you have a CAI? (before you respond, do some warranty searches)

 

I have a little over 500 miles on the car, with no mods and i was at a light, with the AT and the car stalled, so when i called the dealer, they asked if i modded it already, and responded NO, which is true, but i guess if it is that easy to install, if i need to bring it in, i will switch it out when needed....if they give me a hard time...they even offered to do the installl? is that a good idea for the dealer to install it, or WAY BAD cause they know you have it....

 

It does'nt matter if they know you have it...if something goes wrong that was caused by the CAI they will be able to tell. Just knowing you have it not enough for them to void your warranty or deny service. Only if the intake causes the specific damage will they not fix the problem under warranty.
