Hey guys,

I'm not sure if someone already posted this on the forum, but I think this guy raises a good point on creating your own SRI instead of buying an expensive branded one. See what you guys think.

Yup. Did this after I read that.

Did pretty much the same thing on my truck about 4 years ago. Can't say I noticed a HUGE difference, but it gave me something to do...and sounds cool too. I must say I removed the resonator about a year before I made this for the car, so that may be one reason I didn't notice THAT much. If done all at once, I may ave noticed a bigger difference.

Only problem is that SR intakes get heatsoak, so if you're gonna do this you should also build yourself a heat shield for the filter, and there are a few DIY's on this around

 

[zhieson]

I did something like this. Then I bought some flexible tubing and now its a CAI. I'm sure my gains aren't as high as a polished metal one but I know its close and way cheaper.

 

[di2lude]

Put a velocity stack on that and you'll see better gains. :ben:

 

[pally777]

Yup. Did this after I read that.

Hey kennungesser, what air filter did you use here in this pic? What other materials did you need to add to the existing pipping for it to attach snugly?

Do you know if you can keep the resonator there and just remove the air box for the mod that you did there? I'm not sure if the airbox and resonator are all one piece.

Was the sound after adding this SRI loud?

Thanks for any info!

 

[zhieson]

I know an SRI of that length is pretty loud. It's especially loud when you are at 2k and pushing it to 3k uphill. It's a nice sound but its a bit much when you put the pedal down.

pally777. I just used a short piece of black ABS pipe from Lowes, that was left over from the one I built for the truck. The filter is just a cheap one I picked up from Auto Zone.
You could leave the resonator if you wanted. I figured if I left the bottom part of the air box in there, it would still pull SOME cooler air and direct it onto the filter.

zhieson, I am going to make a heat shield once the weather warms up. I have a homemade one on my truck. You can REALLY tell a difference in the heat if you put your hand on the filter side vs the engine side of it. But to be honest with you, this is not THAT loud. Just a little more growl. On the other hand, I may just be used to it. It does sound good at WOT.

 

[pally777]

Does a heat shield make that much of a difference in the summer when the ambient temperature is hot anyways?

Also, I've looked at some DIY and commercial heat shields for SRI. It seems to be just insulation for your intake pipe and a aluminum shield around the air filter. Will that really shield that much heat from the engine? What about restricted air flow?

 

[kennungesser]

I can tell you it feels cooler, but by how much I really can't say. I'll take a pic of the one I made for the truck in the morning and you can get an idea. I just used aluminum sheeting. Keep in mind, there is way more room in the engine bay of the truck, than in the TSX, so I had a lot of room to work the shield.

 

[pally777]

Cool. Thanks. I'd like to see what kind of setup you have for your heat shield. If you make one for your TSX, I'd like to see that one too.

Yeah, the TSX engine bay isn't so big. That's why I'm wondering if it'll make much difference with a heat shield in terms of performance gains/lost.

Actually, I'm wondering... does the stock air box get air from the resonator too? From what I've seen in others' pictures, the resonator seems to get air from the front left bumper vents in the 06-08 TSX.

The resonator is indeed along the path to the air box, that is why it is there. If it was not there, in the path of the incoming air, it would have no effect on the audible sound, thus you would hear the intake. hence when people remove the resonator, the sound is changed.

Also, think about it logically, how else is air going to get to the air box, as it is sealed going to the resonator piping. What else would the resonator be doing in the cramped engine bay?

 

[matiasneto]

the resonator draws in air from the engine bay between the light and the battery

 

[kennungesser]

Yup, what was said above.
I'll have to get pics of the truck later. Man this "lazy" Sunday afternoon was anything but. I thought I had some on my camera, but I must have gotten rid of them.

 

[pally777]

Yeah, thanks for the explanation. I opened up the hood and checked out the intake today. Tried to take off the cover to look at how dirty my air filter is, but I had problems reaching that screw on the top left side (I think it's near a fuse box or something? I'm a noob when it comes what's under the hood). I guess I should get a longer screw driver or maybe a tool set.

I see how the resonator supplies the air to the air box now. In essence, we already have something similar to an icebox don't we? What's the difference between something like the Comp Tech Ice Box and our stock resonator + intake? Seems they both suck cold air from behind the front bumper.

If you look closely, the path of the stock air tubing comes back up into the engine bay to take in air near the battery. I think this is to prevent hydrolock. The intake for the CT icebox requires removal of the resonator and installation of a velocity stack behind the front bumper. This is much lower than the stock setup.

The resonator is also much more restrictive in terms of air flow compared to the CT icebox

Quick questions guys... you notice that tube/elbow coming from the block? and do you guys see that plastic little box the tube connects to before connecting to the intake? is that the oil catch can of some sort?
cuz i know oil gets thru the intake tract @ times..

reason why i ask? i just installed a fujita intake and that portion wouldnt connect @ all...

so what i did was disconnect that whole tube completely... and replaced it with a hose from auto zone... directly from the block to the intake..
bad or good?

i noticed that the tube/elbow thing was welded on to another tract.. had green fluid on it... not sure if it was coolant or not..
but yea.. i left that connected and left the only tube disconnected... good or bad?

 

[dmanc18]

Sorry for bringing back such a old thread but what is the OD of the abs pipe and how long is it?

 

[nomaD]

any ABS pipe close to 3.5", remove the rubber tube and bring it into home depot to size it up
