Default Intake question

So I bought a weapon R for my 04RS, and although I love the sound I have two major problems.

1) There are 3 ports and a tee that came with my weapon R secret weapon, but my stock intake only had 2 lines attached to it....what did I miss?

2) It came with the ram air hose, and I plan on removing my passenger side fog light and attaching the hose to it there. However the intake doesnt provide enough clearance. I was wondering if there'd be any adverse effects to cutting the intake just after the first bend (Behind the first port, closest to the filter).

The picture shows how I don't have angular clearance.

1. Connect a third tube to the Tee and run it to the third nipple on the intake. (I had to do this to my 07 cause the intake I purchased was for a 05)

2. I wouldn't chop the intake you just purchased...otherwise you just wasted money.

That filter is pure trash. I've had experience with it before.

I'll do the tee if I dont cut it. I wouldn't consider chopping it wasting money if it makes it work the way I want it to. I'm curious if chopping it will have an adverse affect on the intake flow.

This is a better picture of my lack of clearance.


Race Face, I might change the filter down the line. For now I want it to work right.

Agreed on the filter. It is fine if you simply race your car but not good for a daily driver. That foam lets a ton of particles through.

IF you chop the intake than yes it will effect the performance of it cause they are cut to precision to maximize flow.

Just a question but are they cut to maximize flow or simply to fit the vehicle?

I had an 04 with a Cobb intake. 2 bungs go to the vacuum lines running to the heads. The hole is for your sensor. There should be no third bung for an 04. 2004 was the weird year complete with plastic intake manifold.

I have done this. I have not felt any difference from stock to this set-up. I am not a fan of the actual intake but I have not done any searching to find one where I can connect the tube to the end.


Here's where it comes in at.

should have bought a 94 accord intake. short rams suck in hot air. how fast do you have to drive, in order to make that fog light ram actually work? just cap off the extra hole with a rubber nipple cover from the auto store.

Any reason as to why you're not a fan of the intake? Also you've done 100% what I wanted to do. Also you're running a maf and mine is map which may make some difference. Was it difficult molding the tube into the bumper?

Also the person who said to get an accord intake cause SRI's suck in hot air...that's only partially true. Yeah its hot air when I'm stationary, but when moving the temp in the engine bay is on average 3-5 degree's higher than outside. I tested it using a remote thermometer for like 2-3 weeks. Also the ram air is to provide cold air, as well as having the quick throttle response of the SRI.

I did some testing at work with solidworks, and I'm hoping maybe someone can mention something I neglected.

As I can see, with the full length tube, it reaches a higher air velocity, but its in the middle. Best I can tell is they both have the same exit velocity, regardless of the tube length.

Thanks for all the input guys, I think I'll do this later this week.

(I also did tests without the extra tube inside the weapon r, and the exit velocities were 10-15% lower.)

My car is MAP, the intake was dirt cheap but for MAF, I just cut out a piece of metal and put some liquid gasket on it and mounted it on there to cover it up. As for the bumper mod it was something I had worked on for awhile. It just about drove me nuts and it's not even done 100%. The intake I'm fine with, it's the filter that can be better but I have not found any that you can mount the tube to.
