Got Cold air?... CAI Project
I got this idea from a post from nopistons.. http://www.nopistons.com/forums/inde...&hl=custom+CAI
So first off I bought the piping, http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWN%3AIT
First thing you do when you resieve the product is throw away the filter.. I will presonaly kick you if you use the POS filter.
I cut the pipe after the final bend so the that you have a S type bend with the pipe with a nipple.
I also bought a T pipe from Home depot with two 3" cuplinks.
Now to start, first I took out the spalsh gaurd in front of wheel and removed the window washer bottle.
Then drew a 3" circle over the hole that was for the water bottle and began to drill around it.

This method caused to bloody nuckles.. I'm sure with proper tools this can be done much faster and painless.
After terring out the remaining part of the hole.
![](http://www.wreckedyouth.com/albums/album09/dscn4357.sized.jpg)
I smoothed it out with a grinder bit, and inserted the smaller L shape pipe.

Then I installed the S shape part of the pipe to the intake TB.

I had to make room for the MAF sensor so I cut a small piece off the S pipe and a lager piece off the L pipe..

After putting the MAF sensor in place, I put the T line in place for the VAC lines.

I then put the filter in place and took it for a spiin.
![](http://www.wreckedyouth.com/albums/album09/dscn4368.sized.jpg)
After the test drive I noticed alot more power in the mid range and upper power band.
Final product:

This mod is defenitly worth the bleeding nuckles.
Totoal cost was about $40 not including the filter. with a purchase of a K&N filter total cost should be around $80.

I got just 1 thing to say: PUT IN YOUR BRAKE DUCT!!! if you don't, the first time you hit a puddle in a rain storm, free steam cleaning is all I gotta say...

Brake duct is the same thing, the vent starts in the front airdam which water can get in while your driving.
I dont think this idea is too smart in general as its hard to NOT get water in there when its raining.

Looks nice.
I wonder if one could block off the brake duct with some black plastic, and then not have to worry as much about sucking water. Don't they make valves that can counter-act the problem as well? I could swear that my buddies kit he just snagged for his *cough* Camry had one.
How do you guys think something like this would handle in the winter when it snows and you have slush all over?

You were doing so well until right at the end. That's pretty good work, but it's badly let down by those awful air lines. That PVC tee is completely wrong for this application. Go to an engineering or hydraulics shop and buy a proper brass tee with male hose barbs. Slip the hoses on and secure with screw clamps. It'll only cost a few bucks and look a million times better.

Why not build an airtight heat-shielded box (out of sheet aluminum w/heat-duct wrap, or sheet PVC (IOW plexi) which is non-heat conductant as it is) around the cone-intake, then route the piping down to the brake vent or where you put it? That way you:
A) Wouldn't have to worry about water/puddles (and if you still worry, get a water-bypass valve, commonly sold on eBay or on AEM's website). Fortunate hydrolock isn't really a big concern with rotaries--unlike piston engines. Better to keep water out of there unless you deliberately want it there though (water injection.)
B) Still get unheated non-engine bay air.
C) Get less road grime on your filter.
D) I had a fourth justification but it fizzled.
Nice installation--I'm not trying to shoot you down--I just think there's a superior solution. :thumbup:

I find that hard to believe. If it is done properly, you will get as much cold air to the filter as you do with this setup. The actual HP gains with a CAI are minimal, and any variation in the HP numbers of two properly designed setups would't be noticable - let alone measureable. You wont get the traditional "Ram Air" effect with either system - so the entire focus is getting enough cold air to the filter. Wether it is a well ducted box or a filter on a tube such as this one - the result will be the same.
It also makes me smile when everyone cries "Hydrolock" every time there is a thread where someone puts a filter in this location. The chances of inhaling enough water to even get as far as the TB are pretty slim. Personally I'd be more concerned with the efficiancy of a wet filter eliment. A wet filter will flow less air - if effect negating all the gains you got by making a CAI in the first place.

I drove thru Georgia in major rainstorm for couple hours. so bad I couldnt go past 20MPH. when I stopped to get gas the filter was soaked. the car tried to die on me 1 time before I got off interstate. I know I sucked in water but it never bogged down after that and once it stopped raining it was fine.
because of that though, I will not put my cone under fender again.
I also agree their can be a better way I just havent found parts to do it with YET.
