I was installing my mugen intake last night. It took me so long. The part that took my longest time is the fitment between the filter, the arm and the box. and it is still not finished. I can fit these parts perfectly, i got a gab in between the filter and the box. I can't figure out on where the problem is coming from.

Here are a few pics w/ the problem.

Could anybody help me figure it out how to slove the problem.

Thx in advance.

 

Unbolt all of the bottom pieces so that the intake fits in loosely. Then fasten the clip around the filter/velocity stack first and then retighten all of the bolts down below. HTH!

I have tried that, i couldn't even fit the pieces nicely, even all the pieces are unbolt.

 

i didn't use the bracket for the velocity stack to the chassis. might that be the problem. I didn't use the bracket because it gives me a even bigger gap when i tried to use it. So i left it out, which result a smaller gap shown in the picture.

PS. the chassis of the car is perfectly straight, no accidents. I don;t know y i can't fit the bracket of the velcocity stack nicely.

 

Unbolt the intake arm from the TB, Try fitting the V-stack and air box first and then rebolt the intake arm to the TB. The only other things I can think of is your AC lines are not spread apart enough. But try the TB thing first, you'll have more room to play with, or flexability with the intake arm than the air box. But if you try this, I would suggest bolting the air box on the top of the frame rail first so you know it's lined up right.

 

Check this link out, this may help. This is from my install a few weeks ago. I had the air box fastened to the frame rail before I installed the V-stack and filter/arm

i think i have install the airbox piece nicely, it just that i cannot make the arm to have fully contact to the box. any idea?

thank you Dave_B for keep reply me, and try to help me out.

Duct tape?

 

Here's a thought, connect the filter/V-stack to the air box (keep the v-stack seperate from the intake tube) and then fasten the latch/clamp so that the box and filter/v-stack are together. Then connect the intake tube to the V-stack. Maybe it will work that way.

 

$700 and there is an issure with fitment. damn, guess the ear dyno really isnt worth it.

 

ok, thx i will give that a try.

also two more question.

1) when u attach the V stack to the arm, do u force it in, or do/can u take the spring off to attach the V stack and then reinstall the spring?

2) i took out a tranny mount bolt for this install. ( the bolt on the tranny mount that is on the left when facing the car) Do u reinstall that or do u just leave it?

Until you have one in hand, and are installing it you have no comments... You try installing anything that the instructions are written in Japenese<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Mugen_DC2R &raquo;</TD></TR><TR><TD CLASS="quote">ok, thx i will give that a try.

I didn't take the "spring" off, I loosened it as much as I could, then slipped it over the 2 surfaces.

As for the tranny bolt, yes you reinstall it.

 

any tricks for reinstalling the tranny mount bolt? cau i dun think i have enough room to get it reinstall.

 

I didn't even take it out, but then again I didn't have any AC lines to worry about. I would presume just use a wrench instead of a socket.

 

I'm willing to bet that the insulating tape is what's causing the problem. It's not allowing the tube to be pulled into the right location. I’ve installed many Mugen intakes and NEVER had any fitment issues. And I don’t know what’s with you guys removing transmission bolts to get the intake in… I’ve never had to do that. It's a tight fit but it does go in without removing anything other then the stock intake (even with AC).

And since the intake tube is rubber (and a very good insulator!) why bother with the insulating tape?

 

Do you think the insulating tape on the intake tube is that restrictive and not allowing movement in the intake arm? I looked at it, but figured it was pretty plyable.

yes

 

Still shouldn't have that much of a problem though. It's not shortening the length of the intake arm. I understand it may be more restrictive in movement, but it still should go in fine. Maybe then, connect the V-stack to it then connect the air box to the V-stack (leaving the horn loose) and then clamp the 2 together and then fasten the V-stack and air box to the frame rail.

 

When I install this intake the stock intake tube needs to bend about 1" towards the engine and then stretch about 0.5" to have it slide on to the velocity stack. Looking at the pictures you've posted this is exactly the kind of offset you're dealing with. The design of the OE (untapped) intake tube easily allows this; I'm not sure the tape is allowing the tube to stretch properly.

Keep in mind that the intake tube NEEDS to stretch under normal operation as the engine rocks back and forth. Restricting this may put added stress on the Mugen intake mounting points.

And god forbid you mess up a 700 dollar intake

 

Ok, i have found out what my problem. The problem is the offset issue mention by Baby NSX. The insulation tape has nth to do w/ my fitment problem. Infact, the oil cooler lines are causing problems. I have play with the oil cooler lines around and i finally got my problem solved.

Thx for all the ppl who help.
big for u guys.

 

After looking back, your right, those cooler lines are right up against the intake arm. Glad to hear it's resolved, now give us some feedback!

 

seriously, this problem cost me at least 2-3 hrs. At first i couldn't detect this problem was cause by my oil cooler lines, because i push my intake arm all the way in to the throttle body, so the arm wasn't touching the oil cooler lines.

after i know that it was the offset issue, i tried not to install the intake arm all the way in on the throttle body side. When i pulled out the arm a little bit, now the arm is hitting the oil cooler lines. then i play around a little bit. FINALLY DONE.

I will give some feedback after i test drove it.

Right after the install, i drove it down my street (2 lane street, one up and on down) and floor it. All of a sudden, a cop appear on the opposite lane. I slow down and then i stop my test drive and return back home. Luckily, the cop did make a U Turn to catch me.

So i will give some feedback after i have really feel the Mugen Intake.

Thx once again, guys.
