Mugen air intake system w/USDM front end or J's Racing Tsuchinoko air intake w/USDM front end? Mugen air intake system w/JDM front end or J's Racing air intake duct w/JDM front end? Through anyone's exp that has these intake systems which do you like, why, and which one is the best for performence? Maybe a combo of both the J's Racing air intake duct w/Mugen air intake system w/JDM front end? I have plans in the works to install a JDM front end "someday" Should I stick w/Mugen for now while I have the USDM front end?

 

mugen has proven itself on the dyno but is also $600 or so more.

 

No JDM front plz unless it came that way.. and Mugen all the way

 

Why no JDM front?

 

The Mugen is a proven power getter and the J's is a proven heat soaker to powerlosser. These 2 intakes are worlds apart in terms of preformance. Mugen all the way.

 

Because everyone is tired of it.

 

yeah man unless u bought the car that way then why put a jdm front on it
so ****in with the usdm type rs and go important one

 

Nicely put

i had the J's, sounds great...but that's about it unfortunately.

 

Mugen. The J's is better 3,000 RPM and below, but the Mugen is better up top, where you want it on a B-series.

 

J's = bling

Mugen = performance

End of Story! True Story!

 

I bought a J's years ago when it was all the rage. I'd love to have another to compare it to besides the stock set up. If I ever change it, and probably won't, it will prob be for a short ram and velocity stack, which seems to be the more recent tend. My R moves pretty well even with the J's so I'm not really concerned.

 

Both are so damn expensive why not get a AEM CAI that out performs both?

 

J's Racing intake is not bad with stock radiator
but once you put a big aluminum radiator like Koyo rad. in your R
it would heat soak crazy...unless you want to custom make a intake box to avoid the heat soak...
So Mugen > J's racing
Or u can get the comptech icebox would work out similar to the mugen intake but more affordable price

 

You're funny!!

 

mugen for the win!!! i have both and mugen made more power

 

Loves the Mugen intake!

 

i'll post some when i get home

 

If i am not mistaken, looking at all the threads in the past, AEM is the best-bang-for-the-buck option for the ITR in terms of performance. J's is just a bing bling piece with no performance value.

 

mugen out performs j's

 

mugen

 

Unfortunatly AEM has a huge dip mid range where the mugen performs it's best (approx 4.5k-5.5k), and the Mugen has a dip up top where the AEM performs it best (approx 7.9k-8.4k). That being said, I have owned both. I Sold the AEM 2 years ago and went back to stock for more throttle response and bought a Mugen that I just installed yesterday and test drove today for the first time. My first impressions are that it is very similar to stock throttle response, due to having the filter element in the same spot, but has a much better pull overall.

Also, I couldn't stand the cheap noise of the AEM so I must say I am much more satisfied with the Mugen sound which is like an amplified version of the stock air box with a much crispier sound. Nothing that attracts attention from engine bay sound as does the AEM. I have no experiense with the J's intake, but my guess is as good as yours, I would rather stay stock then to have a ***** whale under my hood.

 

Well then Mugen it is for DA WIN!

 

I've had the J's and AEM v2, they are both noisy intakes.

I hope to purchase a mugen one day.

Does the intake arm effect any performance at all? Because i see a lot people just use stock arms on mugens.

this thread is really depressing when u have a j's racing knockoff (pwjdm).....and u plan on putting in a bigger radiator this weekend....
