is a bit too pricey for me... it looks like a sri with a filter box.. hmm but 1150 for something like that, maybe u shd look around for some user reviews.

You'd be better off with the Gruppe-M or Injen CAIs. The Gruppe-M is still a box type if you wanna keep subtlety. If you wanna be noticed, get the Injen.

I got my gruppe m from MAN autoparts in Hong Kong for about 800 dollars shipped a year ago...they might be worth a try.

I thought the MUGEN had a drop in fillter not a panel one?
Can anyone verify this.

Mugen has two types of drop in air filter, which is the tube shaped one and the normal square one.
otherwise, it will come with the box like pictured above

Gruppe-M is the way to go if you got that much $$

I have a Mugen intake in my DC5r. They have the panel filter in them. You can get a drop in pod, but that is used for the stock airbox. Also there is no need to get a Mugen front bar, just remove the front grill if you must... but after reading simular posts by people, the stock intake is in the same position. The pics don't do the size of the actully air box any justice... the shear size of the filter area is MASSIVE, and the size of the bottom part of the box is also very deep, so can hold alot of air.

Only thing i would reccomend (i was told to do this by my mechanic) was to clean out the air filter oil, as the oil used my mugen is very thick. Clean the oil out, and then use a thinner oil.

If your keen on one, sit back and wait for one to pop up, i managed to get mine 2nd hand, used for 2 months, for $700.

with any type of intake your not going to really notice a power gain, as its only going to be like 5kw or so, if your lucky... and well... your not going to really notice that.

What it does do though is makes the vtec change over point very smooth... all you notice is the noise. I had a SRI before this... i rate the Mugen.

injen got more power, mugen got more torque, gruppe m is the composite of them (thatz what i think so)

I bought my Mugen Air Intake for 730 delivered from a friend in Perth (brand new). Pretty lucky for that one.
Also, Mugen air intake give no noise. It is the quiet type of Air intake.

If you want noise, then probably mugen air intake is not the choice for you.

Also, you need to reset your ECU when you install the air intake.

Hope that helps

why do i need to reset my ECU, and whats ECU? the thing about gruppe m is that you have to cut up some hole or somfing.

you reset it by pulling your battery off for 15 minutes then let it idle for say 10 minutes.

gruppem u dont cut anything.. u get a new cowl top which you replace the stock one

look at my engine bay for example :

its not just noise ... it will also effect your throttle response from low-mid range.

dont know much about the mugen for a dc5, some say you need the bumper for it to be effective others say the bumper wont do shit...

vote for gruppem FTW

gruppem > injen + mugen :thumbsup:

The gruppe m is a great intake if you have the money. The Mugen is also very good once you remove the front grille cover, as you get a direct air feed into the intake tube. Overall the smooth internals of the airbox and the large panel filter make the intake more effective. It is true that the mugen doesnt give a power increase like the injen, but it is fully legal and really worth a look. It keeps the car semi quiet, and with a decent tune doesnt really stuff your power gains that much. My car has 138kw at the wheels and i have one, so it cant be too bad.

If u ask me, dont get one man.I got one bck thn for me car its was shit man.only maked a little more power thn a stock one, i dyn it so i know.
get a cold-int "injen" its better..

when i sold it to a mate for my,1week after he took it off "kekeke" n said the same thin "IT WAS SHIT"

Its all depends on what you looking for......if you have a aftermarket bodykit with intake hold in it.....it will make some different.....if you run stock front bar....coz you are not getting free flow air direct to ur box so it not that noticeable......the intake air temp different of mugen and GruppM is about 3-5 Degree different with stock front bar.....1-3 degree different with aftermarket front bar......injen is giving you more top end power but the look of it is not really legal if you get busted....

hey guys ,new question coming, now i got the gruppem intake system, and got mugen front bumper as well, if i custom the airbox like mugen one, give another admitting port, is that make more different???

Not unless you wanna hack up your Gruppe M.

I wouldn't bother... just like everything, to much of something isn't a good thing...

XP02ED
05-09-2007, 04:38 PM
cant do that with gruppem as it relies on the air comming from the bonnet as it then hits the filter, if you make a hole prior to it your feeding air the other way

yeah but injen is so much cheaper, picked one up from jdm yard myself for a little over $450 i think it was.

about 6kw gain, feels nice, sounds nice :) that's my experience anyway!

17-10-2007, 11:43 AM
Another vote for Injen, 11kW gain (DC5S), definitely feel the difference in response and power across the rev range now! :)

With all these CAI, doesn't the stock or mugen style intake work better at higher speed due to the fact that as the car travel faster, more air can be forced into the engine 'cause intake inlet is exposed at front of car?

Off course this theory won't be evident on the dyno 'cause da car's not actually moving forward to pick up higher velocity air.

aaronng
17-10-2007, 01:15 PM
For $1000+, you're better off with some good headers like Toda. You get more gains there throughout the rpm range.

Jackson15
17-10-2007, 01:17 PM
so at what road legal speed do you think the mugen becomes more beneficial than an injen if that is the case ?....pretty hard to answer but i like the mid range benefit i get before vtec even kicks in with the injen.

can be going faster than 110 in second gear so not really too worried about loosing any top end power as that is as fast isi can go legaly anyway :)

I have already got the full TODA system,
I’m also looking at getting a new air intake system too, can’t decide between INJEN, MUGEN and Gruppe-M?
1 thing that keeps coming into my mind is that all three are different. Hard to choose?
Currently got an APEXI SRI (dry filter type) that works fine DYNO proven 4kw @wheels on my car!

There are a few recent Injen dynos up on the DC5R and DC5S. The GruppeM and Mugen are very pricey and give you the worse hp/dollar. I'd put it towards a k100 or kpro then.

You have a DC2 ... the mugen airbox is better on the dc2r and the ek9 then the dc5... its different

If you got the Coin go the Gruppe-M, results on the Dyno aren't as strong as an Injen, but dyno's dont show throttle response. Injen are VERY good bang for buck :thumbsup: Mugen are also good when fitted with Mugen Front Bar, they are also a little quieter then the Gruppe-M. Personally i love the sound of the Gruppe-m, although some don't!

When they refer to "top end" they are referring to your RPM, not speed.

Put it this way, if you spend 25k + on your car.. You want the best.. if you dont wna go all out on your car.. get the Injen.. if you want the best go for gruppem or mugen..

i have got a gruppem.. from a typhoon intake and aint looking back.. but if u got a budget then go for an INJEN....

u can pickup a 2nd hand injen around the $300 mark.. buy a brand new gruppem for about 900ish... If you can source a 2nd hand gruppem for the 600-700 mark u should grab that ;D

An INJEN isn't a budget intake.

Just because its cheaper does not mean its worst than the Gruppe-M or Mugen. In fact it puts out more power than both of those intakes, however you'll be sacrificing throttle response slightly because it is a true CAI.

love it when people talk about 25k+ being a massive investment into a high class big dollar supercar or something...

anyway, if you want to waste your money but be able to brag about a name, and being able to buy it, then buy anyhting other than Injen... just my 2c

Save the 500 dollars and put it towards something that will give you real power...

Mattski_VTIR
16-11-2007, 04:00 PM
Problem i find with the INJEN is its Cold Air Feed location, People think becuase its away from the Engine and down low its getting cold air... This is only part true, as people forget that road temps are significantly hotter then ambient air temps.. A $500 intake is not "cheap" in my books, but a bargain when you compare $/hp against Mugen/Gruppe-m

if you are buying this car for a dc2r it is highly recommended, as it is a quality part and gives quality gains.. ive seen these as low as $860 shipped, so look around and you can always get a cheaper price.. if you look at the engine bay of most dc2r's they have all chosen the mugen over the Gruppe M or any others, but if price is a problem then go with the cheaper options.
