First thing you need to do before you even start is go to the hardware store and pick up some clamps for the hoses that Injen supplies. Your existing clamps (which they tell you to use) don't fit.

First remove the bumper assembly. There's a separate DIY here if you need it.

Note my dual horns from a 97 Dodge Intrepid on the lower right. Now is the time to change your horns if you're so inclined




Next, remove the battery and tray





Next, remove the 3 blots holding the air filter assembly on as well as the connection to your sensor and remove






Remove the flexible air tube that goes to the manifold




Now remove the tube from your fender by pulling up and out. This is kind of tight





Next there are 2 screws holding the resonator on. Take those off and remove





Look at how far back the brake booster sits




Here is when I changed the sensor from the stock to the CAI


Now it's time for hoses.

Start with removing the PCV hose from the cover




Remove the manifold coolant line an replace with the supplied hose. Blue coolant will leak out a little




Remove this hose (not sure what it is) and replace with the new one.





Replace your PCV hose with the new one, make sure to use the new clamps


Using the supplied zip tie, attach the wire for the sensor to this hard line. We'll hook up the coolant line in a few minutes.






Some people have cut and some haven't. I decided to cut my inner fender so nothing rubs. Use the directions supplied for the size.






Install the new vibra-mount





Install the elbow with the small end to the manifold





Install the intake from the bottom. You will need to move some of the inner fender to get it in. Once you get past half-way it slides right into place. Hook it to the other elbow end





Install the nut and attach the intake to the vibra-mount





Hook up the PCV and vacuum hoses to the CAI, also hook up your sensor wire to the sensor





Don't forget your filter





Install the bumper and start the car. Let it idle for 15 minutes, I had no CEL, so I was good to go!


All that work and this is what you get to see







Even better, this is what you hear!!

With the amount of pics I post, it would take forever to replace them on all the threads.....I cleaned up my account so I have the space...now it's just a waiting game.....Sorry for the inconvenience

I really appreciate it. I've been driving around really carefully cause i wasnt sure if they were hooked up correctly. Now I get to see how this intake sounds on WOT!! THANKS

[somedaySI]

I'm installing tomorrow... the largest hose seems a little loose where it fits over the intake. I do have a hose clamp, but it seems like there is still possibility for a vacuum leak. Is this normal? Thanks

I did my installation yesterday with a friend, and I just have to mention that this is the most pain in the ass CAI install EVER! Taking the bumper off only took 10 minutes but getting the intake pipe up into the engine bay was crazy. I practically had to kick it into place. Also, getting those plastic clips back in under the bumper was really frustrating so I got 2 of them in and just left the rest out. Oh well. Hopefully you guys are more mechanically inclined than I am. Oh, also, this thing sounds AMAZING!

I would use another hose. Mine fit ok but I did have to use different hose clamps because the ones supplied didn't fit

Yeah, I had a hard time too but I finally found the angle that it slid in with a small amount of effort and 3 small scratches. You may not have had the bumper lined up perfectly. I 've had mine off several times and still am able to put all the clips in easily

06blaksi - I just received my CAI yesterday... I can't wait to install this bitch. I was wondering if you still remembered the dimension of the hole you had to cut the fender so there would be no rubbing issues?? Thanks bro

[06blaksi]

I didnt measure. I just held the intake and cut with a knife, trimming more and more until it sat in there right. If you look at the pic where my hand is it looks like I made it as wide as the gap under the frame rail

Alright. I see what you are saying. Well 30 minutes til I tackle this install...

If you want, I can take a pic of it now, finished and you can get a rough idea

Thanks bro. I actually finished the install w/o checking online for the pic of the cut. Only took me 3 hours to install with a friend helping. probably would have took us a little less time if weren't grillin up some chicken.

Your DIY helped out a lot though. But all-in-all a pretty straight foward install. No issues even with fitment. I have only one scratch, but other than that everything is all good. <-- even more than before

Edit: You must spread some Reputation around before giving it to 06blaksi again.

[06blaksi]

I'm glad everything turned out. I ended up with 3 scratches but you can't even see the damn intake anyway so it doesn't bother me

How often do you remove the bumper and clean the filter?
