Hi, after reading over some reviews and dyno results. Im still having mixed feelings about the J's intake. Actually im getting a plastic knockoff because there is **** all difference between the genuine one.

Most the reviews have been on B18c5's.

My mods include:
JDM Gen 2 B16a - 10.7:1 Compression
Stock cams
2 layer headgasket
Ported & polished head
Bored throttle body
Short ram intake
4-2-1 header
2.25" mandrel bent exhaust with N1 muffler.
VAFC

Will the J's racing intake be beneficial to the smaller displacement B16a? We all know the B16a has **** midrange torque so will the J's gain me some torque in the midrange?

I'd like to see some dyno charts on B16a's as well.

Comments?

Thanks a lot

 

i put one of the plastic knockoffs on my b16 and am very happy with it. one of the main selling points of the j's is the enhanced throttle response which is very nice. i dunno about really gaining any midrange torque, but you shouldn't lose any either. the only kind of bad results i've seen on this intake is when comparing it to the 3" AEM cold air intake on a b18c5. i picked my j's copy up for $50 shipped so i aint bitchin' at all.

BTW- it is loud ecpecially after vtec crossover. also, i am assuming that you had your intake manifold bored along with your throttle body?

 

Thanks for that. Im not actually sure if my intake manifold is bored as I bought the car with these mods. I read a few threads about the J's losing power but a majority of the posts have good feedback (hope its not the JDM hype). I can get a Simota J's knockoff for around $120 US with filter. (Im in New Zealand BTW). The reason i ask about the midrange is I previously bought one of these 5" ARC copy pipes and that made me lose a lot of midrange power and torque along with throttle response. The car didnt feel "alive". So i dont want to make the mistake of purchasing something that will do the same thing.

there was a recent post with dynos on a stock B18C5 showing a 10WHP gain from going from a real J's to an AEM CAI.

 

i feel a little dumb, but what is a "J's intake" ? and a J's intake knockoff???

 

Places like Memoryfab and PasswordJDM make copies of the J's intake. I got the password version. Go to their site and they have a side by side of the real Js and theirs. I happen to think theirs is better quality and it only cost me 150 bucks VS 250 for the real Js.

Yeah thats cool but, will it be as effective on a smaller displacement engine?

yea on peak power, but in the throtle response and low end gain the J's OWn'd

 

OK so conclusion is the J's give good throttle response and low end/midrange?

 

that post J's vs AEM CAI the aem killed it all the way across the band and badly on top https://honda-tech.com/zerothread?id=1194128

personally i would get a injen intake....they seem to beat aem quite often in intake comparisons

it only gained in mid to high....and low end and throttle response the j's was on top...which the J's was design for raod racing and auto-X conditions that need quick throttle response

if you look at the dyno it only made power below 4k....dont know about you but im never down that low in the band when i auto-x.....glad i sold my j's....going itb's

over-rated...i know

also throttle response,,,to me i dont care about peak power

 

I plan to do a dyno test here shortly.. AEM CAI vs Password JDM intake. It will be a back to back test, maybe 2-3 mins in between runs. No other changes. I can't wait to see what this test yields. Hopefully results will be in in about a month.

 

the other AEM CAI test used the 3" ITR version. theres more power to be has since the GSR and B16 versions are 2.75"


oh and i didint notice hardly any if anything at all as far as improved throttle response after going from my AEM CAI to the J's

 

Peak power means little to me. Its more about the power under the curve that makes a car "fast". We shall see what my test reveals.

yea, but my *** dyno doesnt feel peak power. and the car felt faster with the AEM

Ok thats B18c-R. What about the little B16a?

well than you should sell me your js and go back to an aem lol

The j's is good for shooting some idle air into your car but as far as a continous flow it doesnt look like its built to mainain a high intake velocity as an aem provides a continous flow, and also has idle air, and brings up cold air from the wheel well. As opposed to sucking up hot engine bay air.

Anything is better than stock imo, but an aem with an apexi filter would be superior in an all around power application.

lol...i just prefer and mandrel bent 3 inch alminum pipe with a good filter

that's what i used to run, but with some self-adhesive aluminum backed heatshield wrap on it that can be found at either home depot or lowes. seemed to work because it ran about the same after first starting it as it did after a while of driving (the pipe didn't heat up after driving from the engine temps).
