Im currently using the stock airbox with the OEM filter. I would like to stay with the OEM filter because I want better filtration to keep my engine healthy.

What gains could I expect with a CT engineering icebox if I retain the oem filter and intake arm?

Other engine mods are a Toda header, carsound cat, OEM mid pipe with bottleneck delete, and a spoon 1st gen street muffler.

 

Not much, if anything.

 

I disagree, stock airbox sure seems to kill power unless it's modded to remove the resonator.

IMO you will be much happier with the CT icebox, even with the OEM filter element.. though I have to wonder why you think the OEM filter does a better job than an aftermarket filter...?

You have a Toda header, CT icebox is like 1/8th the cost lol Buy it and try it out.

 

I've read that test where they compared the k&n filter to OEM paper and there was a lot more dirt let thru

Its somewhere online if you google

 

HP, none. Intake sound, like all aftermarket cai, really nice specially from 3K and up.

 

Love mine I have there filter as well married up with king motor sports samco intake pipe.

 

I always thaught this would be a nice combo. As far as gains you wont see much if anything at all with the oem filter and arm. The comptech filter is much bigger and the arm piping is much bigger as well. The filter sits in a grove in the ice box and the lid fits over giving a nice tight seal. using a oem filter and arm will most likely leave a opening. This intake worked very well on my old Jackson super charged setup years ago. My only issue was the lid would pop off on the dyno but no biggie.

 

Also, it's worth mentioning that the CT foam drop in filter has a built in velocity stack in, while the OEM filter does NOT.

im using the samco ITR intake arm with the ct engineering filter on stock air box with the resonator cut out.. the piping that is below the airbox has a velocity stack at the end of it facing the turn signal.. and I have the inside of the turn signal cut out for a ram air effect. smaller diameter piping below the stock airbox compared to the comptech box's lower piping, but I believe the velocity of air from the smaller diameter piping leads it to have more tq mid range. just a guess tho..

if it ever rains I just unbolt the lid off the box and voila, short ram intake (even tho I noticed a torque low/midrange loss when the lid is off.. heatsoak probly plays a factor as well as the shorter air travel/ loss of velocity)

I've been researching allot regarding the ice box lately and can share some good info.

First off, taking the lid off results in a loss of power, there's a YouTube video where the guys from ct dyno an ice box and try a run with the lid off.

Secondly, I used the smaller diameter OEM piping from the resonator, cut it to face it forward, put a3" v stack on and loved it, until I saw a thread on team integra where the person who originated the home made icebox went to 4" piping with a 4" v stack, similar to what the mugen intake piping is like, and reported better throttle response.

I went to 4" piping just yesterday from the oem piping, and omg what a difference! Like night and day!

Also, the ct filter uses the foam UNI air filter material, which is what you will find in 99.9% of dirt bikes, if they can hold up on my dirt bike, a UNI filter inside an air box should be just fine.

And just like a previous poster mentioned, there is an ugly bend in the stock filter neck, the ct has a built in v stack with a smooth bend, that alone should aid in performance. I'm still waiting for my ct filter in the mail.

Lastly, the intake pipe makes a difference, I originally cut my 3" aem cai to mate to the home made icebox, but bought a top fuel intake and filter, mated the intake to my air box, and mated the filter to the stock filter neck.

The top fuel intake feels much more responsive than my cut aem, especially after going up to 4" piping last night.

Hope this info helps, I've been reading about the ct ice box the for the last month while building my own intake, and im glad I've experimented with different size piping, as I'm really happy with the setup I have now, the last piece to the puzzle is the ct filter.

 

Remove the stock resonator and build piping with a v-stack. Boom, icebox for cheap and OEM air box remains.

I have the comptech one and I like it. I prefer a box design over an open filter hanging somewhere and soaking up engine bay heat so that's why I bought it originally. If I had to do it again I'd mod the stock one as mentioned above.
