Just got my intake installed last night; below is a link to the final product.

The difference in power is definately noticable - especially when shifting into a gear (seems smoother somehow). The sound difference is there in low rpms, however it sounds REALLY incredible above 4500 rpms and when you hit VTEC...WOW!

certainly! Let's see, tools for the job:
Pliers (Needle-nosed and regular)
Screwdrivers (Flat and Phillips)
Flashlight
A good floorjack or some ramps
Sockets, with an extender
Tie wraps (or something better for routing vaccum hoses when you are done)
Very sharp utility knife (Need to cut some underbody plastic and might need it to slice off old hoses)
Tape Measure/Ruler
Before you start:
Take the two red, supplied hoses, and measure the interior diameter of them. The smaller one should be 5/16" and the larger 1/2". If they are too large (like mine) go to a parts store and buy about 2 feet of each (you can trim it shorter as needed).
Remove both leads on your battery!! You do NOT want to chance those fans coming on with your hands down next to them.
On the back of your factory airbox there is a sensor with two vaccum hoses attached. One of those hoses goes to some undeterminable place down low on the drivers side of the car...remember which nipple that the hose attaches to on that sensor. I do not know if it makes a difference, but better safe than sorry.
The install:
The hardest part of the install is removing all of the old hoses, underbody plastic and the factory airbox. Start by removing all of the hoses that attach to the factory airbox. (Quick hint, for easier access you can pull up on your coolant fluid resevior to relocate it to a better location while you are working).
I found that many of the hoses were REALLY stuck on and the best way to get them off was to take two pairs of needle-nosed pliers and dig under the edge of the hose. Then carefully roll it back, place the other pair of pliers deeper and slide around the hose - alternate this technique until you can pull the hose off the nipple. If you have any problems with the clamps, try using a thick pair of pliers to squeeze them together (leave the clamps on the hose - you'll likely reuse them and it is slightly easier to take them off than to put them back on).
After you have removed the airbox - you will have to remove the little eletrical sensor from the back of it (held in with a phillips screw). Once you have it off, remove the bracket (another phillips screw) and set the sensor aside - you will need it later.
Remove the metal tubing/loom by disconnecting all of the hoses - careful, some of these may leak coolant - use a rag to catch the drips. Be careful not to lose track of where the hoses are - you will need to reconnect everything when you are all done.
Under the bumper remove basically every bolt you can find.
Then start on the stupid, really annoying (unless you have a lift) clips. To remove the clips, yank out the center with a screw-driver or needle-nosed pliers, then the clip will slide out...I broke a BUNCH of them...don't feel bad if you do; they are inexpensive to replace.
Now that everything is off the car, attach your 5/16" hose as shown in the directions; it should fit snugly however not too hard to pull on/off...clamp it down.
Now install the upper part of the intake (this is the piece with the 2 hose nipples on it). First install the rubber neck onto your air-intake of your car (the skinny end...I used needle-nosed pliers to push it on. Put on the clamp nice and tight. Now install the upper intake piece - and tighten the clamp just enough to hold it in place, but you could still twist it if needed.
Connect the 1/2" hose where shown in the directions and re-attach the hose coming from the driver-side with the factory clamps. Note - the directions say to use the of the provided clamps for the 1/2" hose...I only used one on the intake side. On the engine-side I used the factory pressure clamp because of space problems (the clamp wouldn't fit properly).
Grab the sensor you set aside and use a factory bolt (one of the three that was holding down the airbox) and bolt it to the back of your intake (there is a little bracket there on the back side).
Now reattach the vaccum hoses (the 1/8" black ones)... this was nerve-racking to get right (I know little about cars btw). There is a hose (factory) that has a white valve/connector in the middle of it. This should attach to the upper nipple on top of the engine (yea, I know it hangs dangerously close to the belt-system...you might want to do what I did and go get a longer piece and route it around and up). Attach the hose (from the indeterminable, low, driverside location mentioned in the BEFORE YOU START) back to it's proper nipple. Take the supplied 1/8" hose and attach the other nipple of the sensor to the lower nipple near the top of the engine. Clamp everything down using factory clamps.
Now place the red coupler onto the bottom of the upper-pipe and clamp it down. Take your lower pipe and see where it is going to fit - you will likely need to cut some of the plastic - it should cut easily with a utility knife if you put a little pressure on the plastic.
There is a rubber-gromit with two screws sticking out of it - this should mount on your frame low in the car. Tighten it into place with a washer and nut (supplied). When you place the lower pipe on, the bracket on it should fit onto the top of that gromit. Use the other washer/nut to tighten it into place. Insert the other end of the pipe into the red coupler and clamp it in place.
Insert the filter onto the end of your lower pipe and clamp it down - do not push it all the way to the end...maybe about 1/2 way? Each to their own here I guess...
Re-check all of the clamps and tighten any that are not snug.
Place the bumper bolts back into place (i have not replaced my under-plastic yet - still debating, but I likely will). Put your coolant resevior back into place. Reconnect your battery terminals. Check carefully for any tools or left-over pieces that you may have forgotten.
Now start the car and pray.
Remeber, not guarentee these directions are correct - it is simply what I did and it worked fine. Follow at your own risk, etc, etc.
There is a definate increase in power in the car, and the sound when you hit 4500+ rpms (especially VTEC!) is _so_ much different. Enjoy!
