K&N panel filter.

[killercolt]

I purchased a K&N panel filter today from Rocket industries for $120.00 fitted tonight now you can hear the turbo spool up and car feels that little bit more responsive.


Part No. 33-2881.

[efti]

how loud is it mate?

worth getting? i might go check one out tomorrow if so.

[killercolt]

Well worth the money it now acuatlly sounds like the turbo is there.

[Steve-B]

I bought the ralliart one, i would say it isnt as loud as this k&n one, but you can def feel the difference when the turbo kicks in, WAY less restrictive.
Good work killer, that your first mod ?

[efti]

well ordered one in from autobarn, should come in in a few days...they were $99. Lets see how it goes

[killercolt]

I still have to fit the inlet pipe also want to lower it by an inch and i want to change the lower intercooler pipe.

efti please put the location of the store for future buyers.

[efti]

no worries

its fentree gully autobarn its on burwood hwy in victoria
there ordering it for me, there was no other record of an autobarn selling one of these in vic the guy told me...so ill let you guys no how i go

Is the ralliart airfilter rewashable like the K&N one?

[lovecolt]

No, Ralliart's not washable. At most you can use air compressor to blow some dirt out of the filter.

[Steve-B]

its an oiled foam replacement panel filter.

[DAC]

Hmm not washable :( For that price I'd prefer something washable.

Looks like I might have to go for the K&N panel but I think I read somewhere that it has poorer filtration? Thats a concern if you intend to keep your engine for many kms...

[lovecolt]

Hence, don't change your air filter for the time been. Wait for more air intake kit to be out. At the moment, only Blitz claim to have a intake kit for our Z27ag.....but i'm still not fully convinced. Someone in euro has one of those latest kit and seems to be fine.

[Steve-B]

meh, its 160 bucks...
for the bang for your buck, i fully give the ralliart filter the double thumbs up !

[DAC]

I used to have a japanese "forza" rewashable panel filter for my 200SX which seemed to work well. It looked to be of 2 layer construction. 1 of foam & the other a finer felt material. Washing was with soapy water & it didn't require oiling either.

Maybe the K&N rewashable panel filter will be fine for the colt as long as its well oiled up & washed out on a more regular basis. For about $100 its seems to be the most cost effective option.

Steve-B, how long are you planning to run the ralliart filter before replacement? 20k kms?

[Steve-B]

yeah, i'll pull it out every 10 thou and check its condition.

here is a filter test

There are articles I've read but can't remember exactly where, claims that for a NA car by removing the stock box air filter and by replacing it with a pod air filter causes a suction/pressure drop and reduction in power.

Hmmms...

[lovecolt]

As far as i know, the effect of a pod filter or any after market air filter on both N/A & Turbo, are more or less the same. Basically, you lose your initial torque (meaning less power at low end) and gain a more free revving top end.

[Steve-B]

but if not boxed or enclosed to stop the hot engine air entering the filter under acceleration it might feel free revving, but you have lost power as you are sucking hot air. thus the power of the standard box, only gets air from the front of the car, and the higher you rev, the more cold air it is sucking in. I have seen the heat haze come off the bonnet vent sitting at lights, it get very very hot under there, so i dont think relocated the air or pod filter to face back to the cabin with no box or pipe feeding it cold air is neither smart or will give you any performance gain. {end rant}

As you said Steve, the heat will be vented out of our evo style bonnet, hence at traffic light, the heat going around under the bonnet is minimal. Therefore, i don't think the heat will affect the air going in as much as the traditional bonnet.

[DAC]

Since we are on the topic of improving performance via increasing airflow by replacing air filters I would like to share an interesting mod I recently read about.

It requires removing the mesh from each end of the airflow meter. Costs nothing & according to the article will improve air flow more than what a filter change alone can achieve! What it does is reduce the turbulence that results from the 2 mesh panels within the intake system. However, you need to make sure that your air filter is in good working condition otherwise the airflow meter is more vulnerable to damage. The airflow meter is found downstream from the air filter.

I have not tried this mod but the theory is sound & I'm giving it some serious thought. If anyone gives it a go with either a std or non std rcolt air filter I'd be interested to hear how much improvement occurs?

Have fun :D

[Rdster]

Steve-B is correct in his post.

Part of the equation for better intake performance is a cold high pressure air feed.
The air flowing around under the bonnet is considered low pressure.

Over the years, I have experimented with foam drop ins, rampods, custom airboxes etc, in various types of cars. The best result yielded was a custom fibreglass airbox using the standard factory air filter element, feeding from a cold high pressure point. All WRC race cars use oversized fully enclosed airboxes, fed by a cold high pressure point at the front of the vehicle. The only place you find pod filters is on open wheeler race cars, ie Formula Ford, Formula 2 and 3.

Here is a more detailed article on the suject.

um, this is the air flow meter..wheres the mesh ?

[fuse01]

lolz no mesh:D

[DAC]

Damn eh :eek: The article I read was not specific for the rcolt but for any vehicles & I hadn't look at ours yet.

Thanks for the pic, Steve-B. Looks like the mod is already done for our cars. Is the airflow meter incorporated in the air box?

I'd have to agree also with the last few comments. A drop in replacement panel with ducted CIA is the best way to go for better air flow...

umm...i wouldn't remove the mesh from a afm if it was there. its there to do a final filtration in the air passage! if you take that mesh away, which is usually seen in afms from nissan's you can destroy the afm and suck crap into your engine. not a very smart thing to do!!!

that article i posted up was to let you know how well some common brands do in filter tests. i am sure the pod style filters and panels filters will use the same type of filtration but in a different style. its only for you guys to have a look into.

i personally have a K&N pod on my nissan, and i find it better all thru the rev range!

[white horse]

I was going to order the K&N panel filter for my coltR,but i checked the K&N international website ,its show part no :
33-2881 is only for 1.3 &1.5 non Turbo :
check this link : http://www.knfilters.com/search/appsearch.aspx
I reckon its not quite suitable for our ColtR ,it wont hurt but the flow may be same as our standard factory coltR filter ,the K&N may just sounds better, i went to Mitsubishi parts centre asked the price of our ColtR air filter and the staff asked which one i after because he said normal colt and colt ralliart have different type air filter and the part no is not the same, therefore i better stay with my factory filter for the time being.

[Steve-B]

i have the ralliart one white horse, and if you are going for an exhaust, i would recommend getting the ralliart one. Good find with the k&n site as well.

[DAC]

Good find with that link, white horse.

I have emailed K&N & have a guy looking into the matter. Hopefully he'll be able to tell us whether or not part # 33-2881 is suitable or if our rcolts need a different filter.

I will post up the results...

[DAC]

What I wrote:

I am after a replacement K&N panel filter for my car.
Mitsubishi: colt
Year: 2006
Engine: 1.5L turbo
Your website only lists a panel filter for the 1.3L & 1.5L non turbo colt models, part # 33-2881
Is this not suitable for the 1.5L turbo model? or do you have a different part for the turbo model of colt?

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

The reply:

I do not know why the filter for the 1.5L diesel and the 1.5L gas non-turbo would be the same and than the 1.5L gas turbo be different; however since I do not show a 1.5L gas turbo that must mean we do not have one.

So I guess its up to us if we want to use the part # 33-2881 in our rcolts... :confused:

[white horse]

Thanks for the information DAC, i am now thinking to get the Ralliart one but they are not washable and quite expensive ,how much you paid it for Steve B ? because i just got a lukey ultra flow muffler ( straight through ) replaced last week and it flows better when come to full boost and it not loud at all ,its got a deep sound ,only cost $ 150 fitted ,value for money, , therefore i was going to get the K&N one for little bit more performance.

[killercolt]

I had no problems with this filter and i really cant see what the diffrence would be if the air box is identical to the N/A engine shouldnt be any hassles with it.What is the overall thickness of the Ralliart one that might be all thats different.

[efti]

there wont be any difference...there wont even be any performance difference either

if u pull out the fillter all together thats how u will gain a very very small amount of performance...u would do it in a 1/4 mile race for the fuck of it...but wont do jack

fillter will just fillter the air comin in, if it fits in the air box then its right for the car, but obviously for more gain there will be less filtration

autobarn is draining my order, still waiting for my fillter, needed to get ordered and is supose to be in at the start of this month

[Steve-B]

ralliart is about 150-160 horsey.

[Rdster]

White Horse - Would you have the part number for the Lukey muffler? Who supplied and fitted it?

[Rdster]

i went to Mitsubishi parts centre asked the price of our ColtR air filter and the staff asked which one i after because he said normal colt and colt ralliart have different type air filter and the part no is not the same, therefore i better stay with my factory filter for the time being.

The Ralliart Colt has a 2 stage air filter element, the non turbo Colt doesn't.
When you pull the air filter out, you will notice that it has an additional piece of Dacron attached to the vanes of the element. Dacron is used for acoustic noise absorbtion, which can be found in home speaker systems.
As filtration material, it's pretty hopeless.I would say that it's there to quieten down intake noise, to applease ADR.....

The Mitsy part number for the OEM air filter is 1500A050.

However,if you are changing to a different air filter,keep in mind that the air entering our engines when on boost, is up to .7 more than normal atmospheric pressure, so good filtration is imperative.:)

Thanks for your advice ! ;)

[speedracer]

I just checked out that link to the K&N air filters....guess no one has checked it since it was originally put up.
(http://www.knfilters.com/search/appsearch.aspx)

K&N now list a filter for Colt 1.5l TURBO engine.....and its that POD unit mentioned on another thread !

http://www.knfilters.com/search/product.aspx?Prod=57-0649

So I guess previously that search only showed the panel filter for the non turbo and diesel models...but it now has that pod kit for the turbo colt.

I might see if they can be sourced any where in Aus and price them.

these guys are the K&N importer for australia, so they are the people to get in contact with.

Dont see why they couldnt ge the kit in, probebly be around $350 AU

[lovecolt]

I thought i did post up the thread on that K & N intake system.....

Anyway, they are designed for the euro CZT....but since we have the same engine (not sure about ECU) we should be able to use it too.

[Macca]

you did ;)

[phul007]

guys,

I have installed a ralliart filter and noticed straight away the turbine noise is louder (which is good), as I drive the car only on weekends (its the wifes). I noticed that the noise is now gone. The car has done a whopping 2.5K and I would't of thought the car has had enough time to change sounds. I had a K/N filter in my Lancer GSR and after a service the young apprentice put the filter in backwards and as a two piece item it sucked the foam out of the filter against the airflow meter and was stuffing up the vortex normally created and made the engine cought and play up. As the car has just had its first service has anyone else noticed any change in turbo noise. The car goes ok but just sounds different. The noise was there after the service so I dont think the guys have changed it on me.

Thanx
Phill

[Macca]

you cant put out filters in backwards, i tried, the rubber seals is flanged, and doesnt line up correctly when on backwards.
