Default Intake Snorkus _PUT IT BACK IN!

About 3 months ago (when i first got my 2.2L) i took the intake plenum out. I did this because i heard it was louder and improved performance. Well when i took it out a plumbed the intake into the bumper. So i thought it was the sh|t. Lately ive been laying into the throttle hard off the line and the thing just falls on its face. It turns out the "restrictive" intake plenum has a purpose. When your floor it the engine needs to suck a large amount of air quickly, that box is used to store that air. So i put the box back in using a pipe connector and modified it so the box air goes into the intake easier.

HOLY HELL!! No more falling on teh face. I lay into it and the thing gets up and goes. Just thought id let you all know.

I had a PDM Racing CAI (just like Ganzflow, but cheaper). I too thought it was da shiz. I put the stock back on and it works better. Better gas mileage, too.

yeah man, i think the whole buzz about intakes is that its usually your first mod and you think its "da shiz". But in the end it turns out that the well paid engineers of subaru had things right when the designed our cars.

man all im saying is that my car is better off the line with the stock intake. no need for the sarcasim

and just because it makes more power DOES NOT mean that it is quicker off of the line

and you missed this in the post...

well it all depends on what kind of driving you do....
the intake will bring your powerband farther up and give you HP up top....however it will take away some low end TQ and you will have to get farther into the powerband to get going...if you do lots of daily driving(like a grandma) a stock intake is the $hit, you can be low in the RPM's and still get around....but if you like to say high in the RPM's you will benefit more from the Intake.,...
all of this comes fown to how you drive...i just barely put my stock intake back on, and i must say i enjoy it more the the CAI i had...however my car runs out of breath top end(due to the restric. of the stock airbox)...this is on my Mazda, however the Subaru EJ22 and EJ25 are the same way....

well i drive an auto ( i do keep in it the high rpms tho due to my "wannabe shifting"). Yeah intakes are great for a top end, ill agree with that 100%, but everyone ive talked to has said in an NA car...an intake will take a way a little low rpm torque.

so if there is air everywhere then whats the point of the box? (auto: cant really launch..just step on the gas)

common give this kid a brake...you used to be the same way, untill someone tought you stuff about your car(or you learned)....
we all got to get started somewhere....


also sell your car and get a 5spd....i had a 1996 2.2 AWD 5spd, with catback...beat an Audi A4 2.8 w/ exaust intake and a chip...i think i beat him by like .2 of a sec, but his top end was like 3MPH faster....but i still won....The 4eater, is worthless unless you get it modded...just get a 5spd...yes i know its easyer said then done

so that the intake is quieter...old people dont like loud car...its for the same reason why your car has sound detning(sp?) material...makes the car quieter...

I'm going to say... hmmm... mid 16's.

I'm glad to see someone so enthusiastic about an Impreza besides the WRX, but in all serious-ness, I'll bet your autobox is holding you back. Before you race, reset your ECU. I know it sounds wierd, but I've used this trick on old auto subies before, it really crispens up the shifts.

I'm sorry... I remove my entire intake from my 2000 Legacy with the 2.5 liter engine, and replaced it with straight 3" piping. I added some foam into the intake as well to spiral the air as it comes it (it actually acts as sound dampening material, but it helps a little for air flow purposes as well). Guess what? I haven't lose any of the bottom end at all. In fact, I think I gained low end.

I'm going to switch to a Cobb intake shortly. I also slip the clutch to 2,500 rpm when launching, 4,000 rpm when I really want to launch it (only done that once so far). I've lost a bit of milage, but I've also been running Plus gasoline due to predetonation. Since it was predetonating during the summer when it was 100 degrees out, and it's now 70 degrees out, I'm switching back to regular and hopefully my milage will go back up.

ok american youth, ill set your guess at 16.5. Yea i am very enthusiastic about my car, everyone has a WRX or STi so i think the GC8's are much funner(not a word).Yet my auto is holding me back and im thinking about goin to my local junkyard and getting all the parts i need for a tranny swap cause theres an 2.2 impreza there. Well i'll do a run without the reset and then do the rest with and i'll let you know the results.

you know what, at about 1000-1500rpm, if I floor it, my car falls on it's face. it's something I deal with. Taking out the restrictive snorkel freed up some power above this area... I never would floor it at 1500 rpm anyhow, so it's of no loss to me.

yeah it didnt bother me at all. but im goin to ATCO(1/4 mile) next week and i know if i were to floor it my car would run and even slower time than its gona run. JonofScio: you want to take a guess on my time? theres 10$ in it.

My manual EJ18 is de-snorkified and it's given me better throttle response and a cool "vmmmm" sound. I'm happy with it.
