For those interested, here are a few pictures of the CAI that I made which is very similiar to the Comptech Icebox. The piping cost around $6 and I painted it flat black to match the airbox. The piping is 3" thin walled PVC piping which is pliable enough to conform to the oval opening in the bottom of the stock airbox. The intake inlet pipe is a 3" speaker port .

I have noticed a increase in performance since installing it. There is very good power output throughout the RPM range and a suprising amount in the low to mid RPM range. Which is a common comment expressed by people that have the Comptech Icebox.

I'm posting this information because I feel that it is a very cost effective means of achieving similiar result to the Comptech Icebox, but at a fraction of the cost.


Here are three pictures of the intake before I installed it:








Here is a picture of the intake with the turn signal lens removed.



You will noticed that the positioning for the intake inlet is different from the Comptech Icebox. The reason the different placement is because I modified a turn signal lens for track events to route cold air directly to the inlet for a ram air effect. I modified the turn signal lens by cutting off the bulb socket from the rear of the lens which produced a rectangular opening with an area equal to a 3" diameter pipe and the front lens cover was removed from only the front bulb only. I know a picture would be worth a thousand words and I will have a picture of the modified turn signal lens very shortly.

 

thaks BSQ, but I don't see any pix

Red X's are BEZERKER!!!!!!!

Sorry about that Yoshi, for some reason geocities does not allow the picture to be viewed sometimes. Here are the links to the pictures:

Incase you are eater to see the pictures of the modified turn signal lens, here is the picture that gave me the idea. The picture is from Andrew on the this forum. He uses it for brake ducting. Mine is very similiar to Andrew's, but I didn't paint the inside of the duct. You may also notice that Andrew cut an oval opening in the back of his lens, but I just cut an rectangle which had the same area as a 3" diameter pipe. One thing that I didn't mention was that I was able to find a downspout connector at Home Depot which is made out of something like ABS plastic and it is used to connect a rectangle downspout to a 3" PVC drain pipe. I was able to slightly modify the connect and is has nearly the exact rectanglular opening at the turn signal lens and it fits perfectly over the intake inlet. I will also take a picture of this as well.

sumpins broke. no worky, no peectures!

 

i think i need glasses, i see X's
hehehe
thx for the info, but i cant see the pictures

 

I need glasses too unless that's a White Debadged Type R with all painted white engine bay and wheel's and tires????!!!!!!!!!!!!!!!

 

can you please email me the pictures. i'm especailly interested in how you modified the turn signal/lense. i've been driving around with no turn signal trying to figure out how to modify it!

Here the explianation for all the red Xs. Looks like I broke the rules. The problem should be fixed. Sorry for the inconvienence.

BSQ comes through again! (I already have my Icebox though...)

 

I actually have been running with this setup for atleast 2 months if not longer. But, I didn't want to post anything about it until after I had tested for awhile to make sure that there were no issues.

 

To see the pictures click on the link and delete http://, then they will show up. A common problem with geocities.

 

yo bsq, that some trick stuff man.

 

Hate to put a dampener on this, but isn't PVC the type of plastic that melts or omits dangerous gases when heated?

 

Lol turn on the Air and u will soon feel lighter which will make u seem like your driving faster!!!!!!!!! lol it shouldn't get that hot though unless driving a real long time at a high RPM.

 

The PVC piping is not close enough to any heat source to be effected, so there shouldn't be a problem.

 

FYI, I created a webpage with detailed information on how to make the "Icebox" intake. Here is the link: www.geocities.com/bretq/DIY_Icebox_CAI.html . Let me know if you have any questions, concerns or comments.

 

i thought the bottom of the stock box is kinda oval shaped? how can u connect the round piping to the oval shaped opening under the box?

 

The piping is 3" thin walled PVC piping which is thinner than regular PVC and it is pliable enough to conform to the oval opening in the bottom of the stock airbox.

 

Nooo, don't use PVC anything man. I heard that when PVC gets hot, some chemicals form and could rise into the combustion chamber. PVC is BAADD!!!

importtuner,

Do you know at what temperature these chemicals form? I'm interested in finding out if the underhood temperatures get hot enough to cause this to happen.

 

The chlorine in the plastic will burn in the form of hydrogen chloride gas which is corrosive. Self ignition temp for PVC is about 507 deg celcius, but this varies depending on who makes the PVC and the quality. Hydrogen Chloride gas begins to form anywhere between 230 and 280 degrees celcius for PURE PVC. Make adjustments for additives.

 

99r,

Thanks for supplying the information on the PVC. I looked for this type of information on the web yesterday and could not find anything. So based on the information that you have given, there really shouldn't be a problem in using PVC piping for this application. Especially since the intake tubing is not really in any close proximity to heat. I was going to purchase a digital thermometer with remote probe to do some intake temperature testing. I could easily see what the temperature is near the intake tube. I would estimate that the underhood temperatures to be around 150 - 200 degrees.

 

I'd have to say that if the underhood temps reached 446 degrees fahrenheit, hydrogen chloride gas would be the least of my problems.

Brett,
I have all of the parts to do the install ready. All that's left is hooking it up to the air box. FYI, instead of using a speaker port for an airhorn, I purchased a 3" to 4" section of PVC and cut the 4" section off to create an airhorn. I'll let you know how it works out.

Thanks again.
