Forum Member SilverS2kF22C1 offers up an extremely helpful do-it-yourself project for installing a new intake in your Honda S2000. We wanted to give him his props and give you the best of his wisdom.
Tools Needed
This DIY project by S2KI Forum Member SilverS2kF22C1 covers the installation of a PRM Racing Jet Stream intake system on a 2005 Honda S2000. It is probably applicable to other years and other intake manufacturers. On a scale of 1 - 10, our Forum member gives this DIY 2 for difficulty. Despite the number of steps involved, it's quite easy and no special tools are needed.
Tools needed
- 10 mm, 3/8 drive socket
- 6" 3/8 socket extension
- Needlenose pliers
- Small channel lock or Lineman's pliers
- 8 mm, 1/4 drive, socket
- 3" 1/4 extension
- #2 Phillips screwdriver
- Small Flathead screwdriver
- WD-40
You should also get a small section (approx 6") of a stiff mounting plate to make up a bracket. You'll see why later on.
Getting started
So this is where we start, with an open hood and about an hour on the clock. You will want to lay out all of your new parts so they are easily accessible when the time comes to install them. It's also advisable to work in a covered, cool space. It's one thing for your car to overhead. No need for you to be there too. Finally, have some gloves and a wet rag handy. It's always nice to do a little cleaning while you are in there.

Step 14 - Install intake tube
Now install the new intake tube using the supplied silicone coupler and hose clamps. Get everything snug to start. You may even need to rotate it around to get everything lined up properly. Once it is installed, use the large silicone tubing from the kit to connect the intake to the valve cover breather port. I put a bit of WD-40 on the connection points to make it easier to slide the tubing on. You can also put the factory clamps back on, but it's not necessary.

Step 16 - Add longer vacuum line to solenoid
Remember the vacuum in-line solenoid? Well, now we finish it. Remove the short line from the solenoid and replace it with the long vacuum line from the kit, reconnect it to the hardline at the top of the motor, using the other supplied zip tie it to the wiring loom that runs along the front cross member. Don't pull it to tight you don't want to crush the lines! SilverS2kF22C1 used a few more just to keep it clean looking.

The results are in
So now let's start up the car and hear how it sounds! 
During the test drive, you really can't hear it over the exhaust (Invidia N1) nor do you really get a sense of how loud the car is to start with but never-the-less, you are welcome to listen.
In the end, the PRM Racing Jet Stream Intake made a difference in the following ways:
- The exhaust has a deeper tone
- The throttle response is a bit snappier
- The midrange doesn't feel as flat as it did before
- VTEC engagement feels/seems softer which make's me think the midrange saw some gains, too, which aligns with the midrange improvement I noticed
- Can't hear it on the video, but once VTEC engages you can HEAR the air rushing into the intake, which is very cool
SilverS2kF22C1 hopes people find this helpful if they tackle this fairly straightforward install!
