Haven't bought a mod for my car in awhile and was thinking of getting an Injen CAI. I don't plan on doing any heavy tuning and would like to keep my warranty in tact so I thought this would be a good mod for $200. I just wanted to get some feedback on whether or not everyone is happy w/ the product....

Please dont turn this into a CAI vs SRI flamewar, etc...
 
Good mod. It was my first. The only thing about any of the intakes I've seen is that they get hot from the heat in the engine bay, which means that any cold air travelling through the pipe will also warm up a little. I doubt it is enough to make a difference. I'd also stick with the injen over other mass producers - I've talked to a few guys who have other companies stuff and they have not had good installation experiences. I originally had a problem with the pipe coming off the turbo, but a slight readjustment of the flange solved the problem. After putting it on, I'd suggest checking the tightness of the pipe clamps after the first drive because the heat will allow the "rubber" to become more flexible and you may want to tighten the clamps then. .... OK prob too much information, but.. have fun with it.
 
thanks for the info...I'd prolly need someone to help me w/ the install since i haven't worked on my car much...
 
the nice thing about the injen is that the installation notes are pretty good. the toughest part I found was in getting the old airbox off - there are a couple of nuts that are a bit hidden, and getting the cone filter back on. It's one of the easier installs to do and a great way to build confidence to try other things. If you haven't worked on cars too much, set aside a couple of hours to do it and take your time. If it doesn't go too well, you can always put the stock one back and get some help... If you want, you could fly me to California... lol
 
The instructions that come with the Injen CAI are very easy. They even include pictures. I don't have much mechanical experience at all and I put mine on just fine. You will feel better if you do it yourself and you might just learn something.
 
Oh Hell.......! You don't need any help , Its so.... easy . I didn't even look @ the pic's... to much , just don't tighten anything down to tight so you can't move it around to get it set in right.

When you get it to that point , tighten all down to the point to where it looks like it is starting to bubble up thru or around the clamp. You should be done then , ENJOY !

Don't sweat the Dove under your hood when you let off the throttal ( thats what its going to sound like , a dove taking off )
 
thinking about fabricating my own CAI from an ebay SRI, could you possibly scan/post the injen instructions? sadly there is no haynes manual for our cars :(

If you want to keep your warranty, check with your dealer first. I had one dealer tell me that a cai was OK and onther said it would void my warranty :wtf:
 
Yeah I'd like to keep the warranty, but I think a CAI shouldn't affect it as long as you keep the rest of the piping stock and don't mess w/ the intercooler piping, etc....but I guess it all depends on the type of dealership you go to..
 
Keep in mind a dealership itself cannot void a warranty. Only MNAO er whatever their abbreviation is can. In this case, unless you drop a screwdriver down the intake piping while installing and turn on the car, then you'll be fine.

(also helps to take donuts with you when you go to the dealer for work... trust me.)

...gobble on!

Good mod. :)
Gives the car a better sound, and it cant hurt performance.
Also, make sure you tighten down the hose clamps... more than you think you need.
Dont wanna blow a pipe off. :)

Good luck.
 
I love me INJEN!!... best thing i did do to the car.. love the sound.. and i noticed a slight difference wit the intake... good luck:D


EDIT:.... opps didnt realize this was in the MSP section... sorry guys!!!:(
 
It's a good mod....my first performance mod, easy install & nice results (sounds, HP gain, looks, etc)
 
I just installed mine last week, and it took me a while due to the cold weather and darkness.
print off the " how to" install notes from this website that Ghost did. It helped me out.
Also, I would look into getting a used one, they pop up now and again, and more are popping up due to people getting FMIC's or hardpipes that come with their own CAI.
I got mine used from a member here for $125 (thanks Prospeed !).
 
call me stupid, but i didnt think the install was that easy.... sort of sum wierd angles and the drilling was a *****-- def worth it tho and it sounds soOOo nice
 
The filter was a total PITA to put in there! Other than that, installation was simple, looks very nice. I need to check my plugs because my car is not performing like it used to, and it's only got 12K miles on it. Accelleration is not as good on the low end, but makes up for it in the top end. But like I said, could be something with my plugs...

I've heard the NGK coppers don't last all that long, and they are cheap, so I'm thinking I'll just buy a new set, swap them out, and see if that does anything.

Other than that, the injen is extremely loud! Still trying to get used to it:D Don't know if I like the sound or not!
