I don't know about you guys, but I hate cleaning foam filters and they seem to require cleaning more often. I don't even think they flow as good as a K&N , but that is just my opinion. So I was thinking if it would be worth installing a K&N filter on the Icebox system in place of the foam filter element, while keeping the air horn base. Anyone have any opinions on this, and have any suggestions as to which K&N filter would fit ?. I just think it would work better, besides Mugen uses a cotton filter on their system. I am not too crazy about these unifilters.
thanks for any info.

anyone ? ttt

 

Comptech filter gives you a 2 hp gain on a dyno..........

 

2 hp gain, that would be over the factory filter would it not, or is it over a K&N ?. thanks

Hmmmm, I did several runs with the stock paper filter and then the Comptech foam drop in.... Comptech filter gave a 1 whp gain and 1 lb/trq loss. So I went ahead and installed a K&N (RU-2710) on my stock elbow. It has to do at least as good as the Comptech, without any of the foam filter hassles.

 

how much is it for the foam filter from comptech?and where at?

 

K&N filter with the comptech air horn will work, if you feel that it is better suited for you. Just post the K&N filter that fits the air horn if you decide to do it. I know that there are probably others that would want to do it also.

 

I posted this link last week.

it might help a little http://www.gtrowner.com/induction.html

 

I've seen a bunch on ITR's with just the comptech air filter gain 2hp on the dyno!!!! This was over the stock filter, I am not sure about the K&N air filter. I saw the dyno my self, thats why I bought one.

 

well I will check into a K&N filter element this coming week, looks like we need an opening of 4.25" on the base and no more than 7.25" in length, I am thinking a tapered shape should work good. I will let everyone know what I think if I find the appropriate filter, K&N makes tons of shapes and sizes should have one in that range.

Wait, can you actually change filters in the Icebox system? I thought that you could only use a comptech filter in the comptech Icebox and nothing else, cause it won't fit.

I had the Comptech filter a long time ago and thought about the K&N retrofit...but sorry, no dice (went through the ENTIRE catalog...)

The Comptech Airhorn as a unique OD (106mm) I think, and all the K&N are either 0.25" short or over on ID.

Might just put the K&N on an elbow next time around...or just clean out the foam depending on what I feel like doing...

I dynoed back to back with the stock element and the Comptech on a completely stock R. 1HP across the board, and 2HP above VTEC. I've had mine for 1 year on the R, and 1 year on the GSR before that. Just cleaned it, and it looks like it is doing fine.

The Comptech has a velocity stack (smooth transition, accellerating air) built into their design, which I don't think the stock filter has. This alone, may account for the 1-2HP.

At the cost of letting more dirt by though, right?

 

I've had one for about 1 1/2 yrs. I clean it every 3000 miles or so. I have not seen any debris getting through the filter although any tiny particles would be too small to see without a microscope. Although it is possible it is not as good at filtering as a paper filter, I am willing to bet any difference is minimal and you would hardly notice over the life of the car.

 

I completely agree with Jon7

Foam elements are to be oiled. The oil traps the dirt, so they actually filter BETTER than the stock element, while flowing better.
