This is my and CKDC2's design. All made for less than $50.00
The piping is a full 4" dia. ABS with a 4" air horn. This is flexable enough to make a perfect connection to the factory hole in the bottom of the airbox. The 4" air horn is from a local speaker shop made for a subwoofer port. The K & N filter connects to the neck of the factory tube after grinding off the factory filter. It all fits perfect "OEM" with the factory airbox and fenderliner.

We decided to go a full 4" dia to insure that the airbox will not be starved for air (especially on my S.C. car).

So you used black ABS piping and fit it inside the stock diameter airbox hole? Or did you fit it over? Home depot sells black ABS pipe but it's thick and I don't think it'll bend very easily. What kind of pipe did you use?

 

My set up looks identical to BHSCGSR's with the exception of the filter. Because my car is N/A I went with the comptech drop in filter with air horn.

In my situation quality of airflow from airbox/filter to TB is important. On a supercharged car quantity is what is needed.

So my set-up consist of the 4" air horn behind bumper, same 4" tubing to 4" oblong opening in factory airbox (removed rubber grommet) then comptech drop in with built in air horn.

This set up replaced my AEM CAI. Results.... Very significant difference! More torque, no felt loss in high rpm range (actually wanted to rev more freely) Allot quieter than AEM, no chance of sucking up water, factory fitment and big enough feed tube to make sure I can't starve the intake box no matter what my future mods may be.

It's Sewer/Drainage pipe available from most home supply stores. It's actually white tube that we painted flat black. As far as fitting it the stock box.....the hole in the bottom of the factory airbox is 4" oblonged. So we just used a 4" sewer pipe connecter with clamps to connect it. We also used a torch to warm the tube up and mold it to the correct size.......

Well, so how was it?

 

Very nice for both cars.

 

nice ingenuity! i admire the work.

 

I used the instructions on BSQ's site w/ 3" pipe for mine, also w/ a speaker port on the end (just happened to have it laying around from a previous project that I never finished). Why didn't you make the opening w/ the air horn face forward behind the bumper light? That way you would have the option of removing the bumper light for a ram air effect during track use. I did that when I was at the drag strip a few weeks ago.

Also, you didn't glue the pipe to the airbox did you? My pipe uses a friction fit in the airbox opening along w/ the factory rubber seal. The pipe is secured w/ zip ties to the lower engine mount, but I plan on making a bracket to secure it to the tow hook, similar to Comptech's design.

BHSCGSR and CKDC2, nice work! ! ! Also, thanks for the pictures. BTW, that air filter look awfully familiar

 

FYI, here is a link to my DIY "Icebox" instructions which PatrickGSR94 mention: http://www.geocities.com/bretq/DIY_Icebox_CAI.html

I think the reason that the air horn wasn't facing forward is because of the size of the airhorn (6+" in diameter). I don't think that there is enough room behind the turn signal lense for that large of an airhorn.

 

Well, we could have gotten the air horn behind the turn signal but we wanted to keep the pipe run as short as possible. Ram air would be minimal to non-existent with the comptech even with the light out and we would have to run another 6-8 inches of pipe. Our main purpose goal was to grab cold air.

The airbox can be completely disassembled.

Kind of hard to see from the pics but the air horn does face the turn signal light, it's just not direct.

I don't think the length of mine is much different from yours, I just used a 90-deg. bend on the end instead of your 45 deg. bend. I have pics of my setup both on and off the car, maybe I should scan a few pics.

 

You would have to see it in person, fitment is perfect where it is.

 

very nice!

 

looks very good. I think i'll give it a try next weekend.

 

nice ingenuity!

 

where can i buy the cone from the subwoofer???

 

So who here would do this instead of an AEM CAI? I was about to buy one from someone in the next few days but now I'm giving it second thoughts. What do you think I should do?

 

i sold off my AEM for $100 and made a BSQ icebox for 10 bucks

 

Hey guys Do you know that when ABS plastic heats up it produces gas. So every time that pipe gets hot you are sucking crap into your motor.

 

Do you know at what temperature ABS plastic has to hit first?

 

Oh yeah I forgot my fenderwell gets over 200 degrees.....Boy am I worried.

 

I found one at my local DIY stereo shop for about $8.00......but you can order one at.. http://www.partsexpress.com/pe/pshow...=268-352&DID=7

How did the sewage pipe fit? I actually tried using the 4" 45 degree ABS street elbow along with a 4" PVC 90 degree elbow and I can't even put the stock bottom splash guard back on properly. The 4" flexible pipe is pushing against a hard line and some tubing in my engine bay and frankly it seems unsafe that the line is under pressure.

 

um, no, first of all the pipe will never get higher than ambient air temperature, and will probably be lower than that due to the air rushing into the pipe. What sort of plastic do you think the airbox is made out of? And actually I don't think ABS plastic is prone to give off harmful gases the way PVC pipe will. But I used PVC for my piping and have had no problems.

Now, a PVC intake pipe connected to the throttle body would be VERY bad! That certainly would heat up and would give off toxic gases.
