DIY * Injen CAI install * Si

***06blaksi*** · 10-28-2006, 06:03 PM

I found a DIY for an R18 but not a K20 so here goes

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.

http://www.8thcivic.com/forums/showt...1711#post91711

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!!

Awesome write up. I never realized how deep the mass airflow sensor sits on the Injen CAI of the Si...

Looks like you had to take off the Driver side front wheel. And is your car frame resting on a rubber mat on the floor?

Injen's elbow by the throttle body has less bend than the AEM's(which is like a 90 degree)

probably good for more/better/smoother air flow

samx109 · 11-01-2006, 11:32 PM

hey man where did you buy your Injen CAI?
