just wanted to show my new intake filter and air breather . the intake filter came from my old mr2 supercharged and the air breather i bought yesterday from kragen for about 12 bucks . the sound is pretty awesome u can actually hear the intake sucking when you drive .

 

I'd get that in a cold air box if I were you...

 

Why does everyone say cold air box is necessary, I dont have one and lots of other owners dont.

Heres a pic of my intake setup with the corksport intake piping kit with heatwrap on it , with bonez maf adapter and K&N air filter.

ps. I know my maf needs to be level so it doesnt have to fight gravity to open the door , and Ive made it level since the pic has been taken.

 

a cold air is BETTER though. thermodynamically speaking, is worth doing.

 

Well how can i make mine cold air ? I plan on doing it sometime, but I dont think the setup I have now is bad just could be alot better if it had a way of getting cold air .

Id probably need to put a hole where the headlight is and extend the intake under there to get cold air, or make a cold air box.

I dont really have the money or tools for either.

 

Maybe not necessary but as the car gets warming your gains get lower. No point in half assing anything right? It s not that hard to make a box either.

 

Well maybe I will look into it sometime in the near future , but right now I dont have the money to do it.

As far as the setup, if I could find how to make a nice setup that WILL work I'd definitely do it, but how does a cold air box make it run colder if all the air is still hot in there to begin with, or does it block out all the hot air from getting in ?

Maybe someone has a pic of a good cold airbox setup on an intake like mine that they could share?

 

Somebody dynoed with and without a cold air box, compared to stock, and without the cold air box they actually lost hp (~5) when compared to stock. On an N/A I think it was.

 

me being a fan of cheapness.

the filter can stay rough where it is. Make two sided box to isolate the filter into the left front corner (stock air box location) out of some plexi-glass from Home Depot. Go to the junkyard and get some weatherstripping from something. bring your plexi with you and check to see what you can find that comes closest to fitting on the plexi. This will make a seal between the two-sided and the hood.

You can also do the above to make a seal between the fender well and the radiator.

Somewhere in the store there is ductwork insulation. youll need a small amount of that to insulate the box area.

The above is the most important deal in keeping the turbo from sucking in already hot air and making it hotter.

From here you can run some ducting from the underside or the frontal area of the car to the boxed in area to provide some cooler air.

 

So you think Id actually be making more power with the stock cold airbox attached to my corksport intake piping kit (i dont know if it will fit though).

If not I'd have to make some kind of custom airbox and I know little to nothing about how to do that.

 

well my car isnt turbo... and a pic of the setup would help.

My hood is actually messed up from accident damage and bent upwards right where the intake is, I wonder if this provides the intake more cold air ? lol

One thing I know it does is it makes my car shake at highspeeds because it messes up my cars aerodynamics.

 

Ummm, stock cold airbox?

You'd make more power if you put a box (wall thingy) around what you have on your car now (cone filter). That will insulate the cone from the engine heat. Quite a few people cut a hole in the firewall and run a pipe from their wheel well area and route air that way to their cone filters.

 

yeah post above works for NA too. Both have air temp sensors.

 

Which way you think provides better cold air ?

I could probably do either one, Im guessing routing another pipe added on that goes under the wheel well would provide colder air than a cold airbox would.

All Id probably need is some pipe and couplers , so long as the pipe would fit properly..I dont know if you need a bent pipe or could just use a straight one (plastic) , or bent metal.

 

I meant you can do both. Some people route air from the well up into a "holding area" where the cone filter is which is isolated from the engine bay by a cold air box. Others attach the cone filter to the bottom of the tube in the wheel well area and just run piping straight up to the AFM and don't need the cold air box. And others make the cold air box with the cone filter inside and use air from the stock intake snorkel thingy (take off the stock air box).

There's probably a few others I forgot.

 

I'd have to see pictures, but I figured routing another pipe putting the air filter under the headllight, and under the car would significantly improve the amount of cold air coming in.

Thanks for the info, maybe I'll just use a stock intake tube for the front of the system like he did and my corksport intake kit can stay on there.

 

wow how neat is that . i took another pic side view in the day , but that intake box sounds like a good idea .

 

stock intake w/K&N insert >hot air cone filter

 

Cold Air Intake > Stock airbox> exposed filter intake

You wouldn't want your engine to suck in hot air.....would you?

 

ya i know im going to search more on how to make that cold air intake box tonight after work . to get an idea on how to make it

 

alot of cold air(ambient to ambient plus 10*>a little medium-hot air(~140*>alot of hot air(~145+*)
fender cold air intake FTW! just gotta cut a hole in your fender yo and get a 45 degree pipe... search for it.

 

yea I did the CAI on mine and it works great

I need a new filter tho, mine is all dirty now

 

Making a cold air box is a simple yet rewarding task. It shouldn't take you more than a weekend to make. There are some people here that made theirs by using styrofoam to model the box, then made the cold air box around that mold.

Alot of people have the idea that an exposed intake in the engine bay somehow boosts the engine's power.
