but think what ya want mate youre entiltled to your opinion if you think they loose power then good for you.

Take a look at this:

the one and only intake thread here - Team Integra

I have a G-Tech Pro RR and I'd love to put a stock airbox without resonator, with good filter and 4" cold air feed up against the J's Racing with cold air chamber. That way I could test it on the road while driving.
 
I have it on pretty good word that the Mugen intake really does perform best out of all of them...

The stock setup is so good that the majority of these aftermarket setups do more harm than good.....who wants +5BHP at the top end if you lose 10 lbs/ft of torque mid-range??

It seems so common that the vast majority of aftermarket intakes may sound better/ give a touch more peak power, but ONLY by compromising torque elsewhere. A quick search/read tends to bare this out....

I wouldnt want to spend out on an intake then have to invest further time/effort/money fabricating an airbox to go round it with no guarantee it will work. Seems silly to me. The Mugen might be pricier but it is guaranteed to do the job 1ST TIME with NO messing about & look neat.

The Mugen CAI gave me mid-range gains on the DC2 right where they are useful. Nothing hugely noticeable at the top but i suspect this will change with a decent map:secret:

"Do it properly, do it once" is my philosophy. No point messing about with inferior intakes when you will forever wonder what a Mugen might be like...

anything with an expansion chamber is crap

why is crap ?

can anyone post a dyno with a j's intake compared to others ?

some ppl i've asked said that j's intake gives nice low end power and big gains at hi rpm's !
 
Hey guys I installed it on mine, at the end of the day eveyone has different oppinions and the way the tune there car....

1st... havent lost power
2nd gain faster responce on lower rev and that bit of extra pull on high rpm
3rd Sounds amazing!!!! They can hear me from quite a distance away
4th Mybe by dyno you might see the loss of Torque... But driving it myself havent noticed anything

Final opinion - wouldnt change it :D nothing like a good Vtec screaming out!!!

your 1 and 2 cant be supported by your butt dyno:p. i have seen atleast 4 different graphs by experienced tuners test the j's and has lost to a $20 ebay intake. everybody has a different setup and will see different results but 1 pattern i am certain of is anyone with 200whp and up arent using a chambered style intake cause of the velocity loss in higher rpm's. when u start upgrading stuff on your motor like cams,intake mani,race header, etc the motor wants to push more air through it faster and the velocity loss is gonna rob some power up high.
i understand that most people here have minor bolt ons and the j's will prob make u some power over the stock units but from what i have seen there more bling than function. a member on honda-tech named Tbone has done some comparison tests on the j's if anyone want to look and dig them up.:nice:
 
seeker eg6 civic with b18 using cams header k tech pistons etc has j's intake...:angry:



power on the street and power on the dyno is completely different story.

yes dyno is a test that you can watch if a car is strong or not.
but the strongest car on a dyno is not always the faster at a track/street.:)
 
Thats very true.... conditions on a dyno arnt them same as on the street

yes this is true, a dyno is only a tool but it does prove that the design doesnt work good at higher rpm's. sure u can have some sort of ram air or velocity stack running to your filter on the j's to help it but the design still will not out preform a properly sized intake.
 
maybe you're right i have not even tried this intake
i'm interesting buying one for myself but if it's not working ?:nerv:
i have and a b18c engine so every tunning movement maters.
but on the other hand this intake is used by seeker on their race car.
 
i know now a days everyone is strapped for $. the j's cost about $300 and the knocks about $180. maybe someone brave can use that $ for a test instead of buying one(lol mostly likely not gonna happen). if u have access to a dyno for a good hourly rate and by an cheap 3" diameter short ram intake and some extra different length peices u can add on to the short ram u can see which exact length it gonna get u the most power everywhere in the powerband. the length of the intake arm plays a major role in power differences even a 2'' difference on the length is huge. this isnt a crazy tin foil hat theory either i have seen it done in person.
all you need is basicly something like this and the arm being shorter then start adding length to it every dyno pass.

hopefully some will do some testing and end the bench racing theory's:D

:nono: man i'm not gonna use somethin like that for intake !
the idea and only of sucking so much dust etc in to my engine ...!! :nerv:
but a 3,5'' pipe with length as long as a test on a dyno could show and a cone filter with cold feed seems to be a nice solution :nice:

but still i have a j's intake in my mind...

lol u dont have to keep the velocity stack on there. jut easier to see the difference on the dyno plus its interesting to see the actual gain u get without a filter. once u figure out the length put a good filter on the end of it(not a **** filter something like k&n or apexi). u sound sceptical of this idea but i can assure u this method with out perform the j's style intake no matter how u set it up.
theres no need for a 3.5'' diameter pipe it will have to step down anyway at the throttle body plus anything bigger than 3'' u are gonna start loosing air velocity.
j's is a nice piece but its seems to be nothing more than a show off factor when u pop your hood. a regular intake can perform better at the fraction of the cost(of course not including dyno time).
 
That carbon one can be found for a much better price, same as the pW JDM.

Their advertising text looks a bit overkill but the item is pretty well, a friend of mine got one from this company in the netherlands:

Honda Civic/Delsol 92-00 J-Racing Carbon Intake System

Made of aerospace quality carbon fiber, the Carbon Fiber Power Chamber Intake surpasses any other intake on the market in quality, and in performance. Our intake is dyno proven to make 6.5 WHP and 7.4 FTQ on a nearly stock B16A engine! Manufactured here in Japan, the Power Chamber is constructed of the finest carbon fiber, and filter elements currently available on the market. The Power Chamber Intake comes complete with all mounting hardware required to install on any DC Integra (Non-ABS), EG, and EK Civic chassis.

Using a unique flared intake tube design, the Power Chamber is able to deliver noticeable gains across the entire power band. This intake gives you the best of both worlds. The security of knowing you are at no risk of hydro-lock, the power delivery that most cold air intake systems can only dream of, and the unmatched style of a genuinely unique intake system.

Through integration of form and function, the Power Chamber will make a bold statement about you and your vehicle. Spectators all around will notice your fine taste in performance products, and will envy your engine bay's unique styling!

Check out the dyno sheet to compare a stock intake box vs. a Carbon Power Chamber Intake.
 
i have one on my ek4 and it works very good your can get them from weaksauceparts.com there was def a power gain and for top end power its works better than any other intake i have owned
 
You got the figures to back up your claims and to prove it's not placebo? ;)
