Poormans cold air induction

[tomdooley62]

Has anyone tinkered with the idea of removing the white baffle inside the airbox? I have heard that this is only there to sort of silence the induction of air. Is this a restriction for air flow.

Also the snorkle that is on the the air box is really close to fender well. Would drilling several holes in fenderwell in direct line of snorkle improve cold air flow?

The way I look at it any of these mods could be easily reversed if need by simply replacing white baffle and as for the holes just cutting a piece of flexible balck palstic and securing it back over the holes.

Seems like any cold air would be better than the setup that comes stock.
Just wondering ?

Any ideas or comments welcomed.

Thanks

If you look at near the bottom of the front where the fog lights are. There are holes on each side. You could take the driver side hole and run a plastic hose from there up to the air box. That will suck colder air in from the outside and plus filter it before the engine uses it. If you have it going directly into the intake then you should get alot more HP added to the car.

Great Idea!
I have some small black flexible hose and it may work and may try that.
Does anyone know the diameter of snorkle inside and out. I know I can go and measure but if anyone has this info I may run out to Home Depot today and pick up some hose.

Thanks,

I would say from memory that maybe a 2 inch or 2 1/2 inch may work best. I think the hole is about 2 inches wide and the hole in the intake is roughly the same.

I bet it would work. I was going to do it but never had the time. I look it over though. If you take the air filter box completely out of the area it covers over the battery, you can get a better look at it. You should be able to then run the hose from the top of the battery, down the back side nearest the fender, down on top of the black plastic fender well, beside the headlights and then down to the foglights and then over to the hole. Attaching it is something I've not really looked into but since the hole is somewhere deep you probably could drill a couple of small holes on each side of the hole and hose and use a nut and bolt to hold them together. If you had room, and you might, you could use the other hole on the other side and run it behind the skid plate under the bumper and connect it to the main hose. Double the air flow that way. Make sure that the second hose is angled toward the way the air will flow so they both don't counter act and cancel each other out. It's like a dredge, one hose acts as the main and another flows into that main at an angle. The force of the main hose will act like a suction toward the second. The second should then suck more air in as the main is pulling air. Then they both work together sucking air as fast as possible.

Let me know if it works well and if you choose to use both holes or just the driver side. After I wrote this, it all sounded so good to me that I might find the time to work on that project.

I removed the white baffle in January prior to a trip to FLorida. My wife said she could detect a slight increase in the sound (while standing outside the car) when I pressed the gas pedal. Also I got 27 MPG on my first tank of gas on the way down but barely got 25MPG on the way back, mostly running 65-70MPH both ways. I have not notice anything negative with it removed. The car seems to accelerate quicker but it may be all in my head. Everything on my motor is stock except a K&N
drop in filter. I still have the baffle removed.

Hope this helps.

I removed the baffle on mine also and I seem to be able to detect a improvement also. I also drilled the holes directly under the snorkle at the fenderwell. I really think it did help letting it breathe some cold air!

That's just it. I think of these things all the time but I never have the time to actually do it. Right now I have a APC intake on mine but I am thinking about trying the hose to it. I saw somewhere that has a chrome hose that bends and doesn't flake off under the extreme heat. I could use the chrome one under the hood to make it look good and half way down connect a black one to the holes so it doesn't stand out bad. If I get it done in the future I'll let everyone know how it works. I have noticed with the APC that when you rev the engine you can hear it suck air in more and that soulds awesome to me! Alot of people think I have a turbo or something big under the hood when they hear the air go in. It's pretty awesome!

I have had my poorman's ram air hose thru this location
for 4 years now and have never had a problem, I used
a 1 1/4" vaccum cleaner hose purchased from Lowe's for 3 dollars. Remove the air box, I found it best to work from under the car, I pushed the hose up to within 1 "
of my K&N Cone filter, then routed it thru the fenderwell
down to the intake duct on the front drivers side. Unless
you are within a foot or so of the PT you cannot even
tell a hose is there, left it black so it blends in.

[tomdooley62]

I still have the original air box and snorkle. I looked and there is very little cleareance between the snorkle and fenderwell. I am afraid if I try to hose it diretcly that the hose may kink to severly to supply any great quantity of air.

And the vacum cleaner hose is exactly what I was thinking of. I have some smaller hose that I got with a sheetrock flat sander that was supposed to be attached to vacum to collect dust, its about 1" or so in dia. This may work but would really like to get as much air to this as possible.

Was the 1 1/4 hose about as big as would fit theough openings to front end near fog lights?

If bigger is possible I was wondering about getting another airbox from scrapyard and cutting the elbow off the snorkle and connecting hose directly to it.

Dont really want to cut my original so as not to void any warranty issues if there would be any.

Just dont know what one may cost at scrapyard though.

All the ideas have been wonderful!

C`mon guys we got a great idea going here lets roll with it!

Thanks,

Dave

That sounds like the way to go , just remove the snorkle all together and run flexible hose all the way down . That way you could probably avoid any kinks . I'm wondering if you could even find a hose diameter just small enough to run through the old snorkle hole and get the hose / cooler air as close to the filter as possible .

[tomdooley62]

I had an old shop vac at home. I used the hose that came with it and it worked perfectly no kinks or bends, ran it right up to the snorkle, was going to let it be inside of snorkle but was concrened with water when it rains entering the hose at the intake end of hose cause it looks like it will funnel air pretty forcefully into it and then making its way all the way to the airbox so i positioned it right at the bottom of snorkle. So far no check engine light and dont really think i`ll get any cause the air box can only accept so much airflow anyway, this is just a way of getting colder air to it. It looks real great cause all is hidden except where it is beside the foglight and then it is hardly noticeable.

Maybe K and N airfilter next. Whats the part # for that air filter for the PT?

[crusinusa]

Glad that worked out for you. Sounds like it was pretty easy to install and setup. I might look into that finally.


Here's one.

Look around because you might find one cheaper that this.

Hi guys,

I have seen other folks on other forums add the cold air hose.
Most of them:

* Moved/removed the black flap in the front intake next to the driver's side air intake.
* Opened up the driver's side plastic inner fender/wheel well cover. (you don't have to totally remove it)
* Ran the airhose up to the point where the factory airbox snorkel juts through the inner fender/engine compartment wall.

This supplied cooler air to the factory intake snorkel without having to do any cutting of the airbox assembly.

I have not done any of this (yet) so I don't know any details about clearances etc. Most of them did drill some drain holes in the lowest part of the airhose to let any trapped water drip out. I have yet to hear of anyone having problems with water getting in the intake.

Since you guys are already in the midst of doing your mods, maybe you can use some of this info and report back how it works.

Later,

Brian in Raleigh

Thanks for the link! But I was really looking for the stock K & N airfilter # for the PT.

Hadnt thought about some small holes in the hose to allow drainage. I think I will do that and pipe the hose more directly inside the snorkel.

The hose was really easy to install took about 15 minutes to do it.

Just remove original air box, this will give you access to the area beside the inner wheel well.

You can look down and see the foglight back side. Just run your hose down beside the fenderwell and it will exit right at the foglight(may take a few times to get it to route the right way but its really not hard to do just a hit and miss method.

Leave yourself enuff hose to position it wherever you want it. i pushed a little more down into the wheel well so I would have enuff if I decided to repositon it.

It fits tight enuff that you will not even have to secure it with anything. When all is reinstalled you wont see any of the hose inside the engine compartment if you are still using the stock air box.
