For those who have removed the intake resonator, but kept the stock air box, did you also throw out the "snorkel" (#8) and "y-splitter" (#9)?



I plan on keeping the stock air box. Does the "y-splitter" send air down into the resonator then back up? Also, does the resonator even suck air from underneath the car anywhere, or does it only get air from the snorkel?

The front bumper on my car, 90 Si hatchback, doesn't have any vents or such to allow air into that area.

 

keep the snorkal lol, so your gonna have to keep the y spilitter

it takes its air from the snorkal

the airbox is sealed except for a tiny hole

the airbox is a baffle.

just get an ebay intake....

if your keeping the oem system for throttle response....take some more measurements to make sure its worth it to u

 

Throw out the #8 and the resonator box. Get some flexible ducting for a clothes dryer and put that in place of the resonator box. Use zip ties or whatever and get it aimed towards the front bumper to scoop up cold air. Cap off the #9 port that goes to the #8.

Ghettofabulous.

 

I use a stock JDM air box works good for me....... jsut a thought if you want the stock look Rob

I took everything off below the air box, including the Y pipe, resonator box and snorkel. Sounds like any aftermarket intake (especially after the Y pipe was removed), and probably doesn't make much less power than an aftermarket piece too. Get a K&N drop-in air filter for your airbox

The front bumper of the 90 Si really has no vents or such for air to come in through.

That's what I was probably planning on doing. I just wonder how much air the hole in the air box sucks in as opposed to the snorkel. And is it that much louder?

The snorkel restricts air flow in order to quiet the intake noise. Trash it.

It is much louder.

 

Well I removed the resonator, which was a bitch. Didn't want to drop the front bumper, so I ended up stuffing my hands inside the lower blinker light and getting the second screw out from there.

For now I'm leaving the snorkel and y-splitter. I'd rather have air drawn in from the snorkel than hot air from the engine bay. Also if I do remove the y-splitter, it seems that the hole on the stock intake box would be too low to even get any air into it: it would just be sucking up hot air from the engine bay.

So now the area without the resonator is just a big empty hole. Since my front bumper has no vents, I was thinking about running a hose at an angle down to the plastic cover so it points down to the ground.


A question about the resonator though: my friend insists that it's purpose is to build pressure, so that the air has some force behind it. I say it's just for sound purposes. The car does sound a little louder over 4K rpms, and I can't say I feel any difference in power.

The snorkel draws hot engine bay air from directly over the header.

The hole in the airbox is rather large, it gets plenty of air. The hole that leads down behind the bumper where the resonator box was is directly below it. The battery is shielding it from much of the hot engine bay air.

Just try taking it off and save the parts. If you don't like it, then reinstall it.

 

Targa250R,

Thanks for the quick responses. I'm gonna drive the car as it is for now, and fool around this weekend and see how it feels after removing certain parts. For now, the stock filter is old and dirty, but I'm waiting for a K&N drop in one to come in.

Reading around a bit, some people complain about loss of lower end torque with the removal of the resonator. Have you felt any loss or gain in power?

 

I took out #8 and the resonator. Then I turned #9 90° clockwise so that it pointed directly down
into my bumper (may want to cut a hole in the skirt under the bumper to let air flow in there.
Last but not least, I replaced #4 with a 90-93 Integra intake tube so that the air flow doesn't get
choked up after leaving the air box. Louder? Yes. More airflow? Probably. Mostly I like it because
it is drawing cooler air and still looks stock.

Restriction will shift some torque down low in the curve (this is a complicated subject so I will keep it simple). When you free up the airflow, you're shifting a little bit of power from the low end into the midrange or high end.

However, the changes are minimal and do not make any significant shifts in torque - just small changes. You may notice a little bit of difference with the free flowing intake, but a lot of it is Placebo Effect due to the change in noise.

I personally don't have any "complaints." The D16A6 has more than enough low-end torque, unlike some other Honda engines I've had . . .

 

I took out everything but the airbox, and I took it out and cut the hole so it takes up almost all of the front of the box. The opening is huge and while opening my throttle body with my hand over the hole I get a lot of suction. That and a drop-in K&N has been my combo since 98.

 

The stock bow with a K@N is only a HP or 2. from a after market intake. i have an AEM now but i am really not sure if it doing anything other than making noise. I notice more of difference in power(well acceleration) buy taking weight than get a tube intake vs stock . That was for my LS powered 90 SI. For my GSR it made a noticeable difference like .3-.4 seconds at the strip.

 

Yeah also and having a stock box and tube soaks in way less heat,your aftermarket aem or etc....tends to soak in some heat from that damn aluminum,keep the box with a k&n,torque reservation is your freind

 

I'm using stock box with all the stuff taken off it, and I sawed the bottom off the stock airbox to let lots more air in. K&N drop in filter too..

I tried swapping it out for a day at the track with a shorty e-bay intake and my car was slower with the e-bay intake. (not much, but slower)

 

unless you want the stock look just get an aem cai knockoff from ebay. i paid less than $100 US.

stock intake is quiet and restrictive
stock with Y removed is loud and still restrictive

The air from under behind the bumper is still colder than the air under your hood.
It might not be direct air flow from a vent or duct in the bumper, but still - it's cooler.

 

i took everything out but a stock airbox and i gutted where the small hole was and i cuted it up to have a bigger air and i can hear it suck loud when the hood is close and i do feel a differance
