I have been looking everywhere for a Cold air intake for my ranger I cannot find one, does anyone know where I can find one for a 94 4.0L

Thanks

yeah its called your stock intake. the factory intakes are cold air intakes thats why you cant find a kit pre made. you will have to make it your self if you want one. but it could and probaly would hurt your engine over time if you do.

Your best bet is to keep the intake setup you have. Aftermarket intakes are out there, but don't expect much in the way of support for "Cold Air Intakes" around here. A more accurate description might be "High Flow Intake" since the air isnt any colder and unless you actually install the shield properly, it will be sucking in normal underhood air. Unless you are going to install a turbo or supercharger, or you're dumb like me and break the airbox somehow, best bet is stay with what you have.

So . . . youre looking for a big cone filter and tube that sucks hot air into the engine from under the hood and hurts performance and gas milage just to . . .look cool? Forget it, because the factory intake is a cold air intake. Unless you fabricate something like working hood scoops there are no cold air intakes for Rangers

This is me being nice.

The truck comes Stock with a cold air intake. Putting a K&N style intake on the truck actually makes it a hot air intake. No matter what the advertisement says.

All you are going to get for your trouble is maybe a kewl sound. and less hp. seriously.

And the stock air filters work better then the K&N oil filter. again seriously they do.

Think about it this way. IF the K&N was so damn good. Why doesn't ford use it?

Last I checked SVT was a part of Ford.

Granted its a Shelby, but my point is this.... if PROPERLY installed with a means of sucking the air from the OUTSIDE rather than form under the hood, then you MAY have an increse in power. your factory airbox has a small duct connected behind the headlight about 2"x4"(I'm guessing, thats what my '99 had). If you just hang a cone off the end, you dont accomplish anything. I don't think any of the walk thrus on this site in the Tech Library depict this heatshield. All you will get is sound. any increase in efficiency gained is thru a less restrictive intake, and as we all have discussed on this blessed site, the engine will only ever take in as much air as it needs. The engine in the picture is SUPERCHARGED, and the cone style intake will not have any effect on what temperature air youre sucking in.

And besides, we KNOW headers are good, but I've only ever seen a Jeep 4.0 with headers from the factory:icon_twisted:

I don't think that's a K&N. That's just a cone filter instead of a flat one. no oil.

And I know you know this. But it still gets it air from outside. a K&N Does Not Come with the tubing or materials to pull it in from outside. its a Scam.

So yes that's a cold air intake. No that's not remotely a K&N piece of crap. Don't compare the two.

Defending a scam?

James86

No, I'm not defending a scam, I'm illustrating a correct install of a cone style filter. if someone really wants to do it, they should she how its correctly implemented, don't you agree? If he's hellbent on changing a perfectly good intake, then might as well point him in a somwehat correct direction....:icon_thumby:

i believe 96 and 97 year 2.3L rangers came with short style tube headers from factory....

really? cool. I thought I'd heard that mentioned around here. I've just never seen a 4 popper ranger from that era. I knew a friend with a 86 4cyl and a friend of mine has a 2008 4 popper. Never looked under their hoods though.

My K&n is a cold air intake between late october to about early march. all the other months it is a hot air intake. hehe...No an open k&n cone air filter won't hurt your power/ gas milage. I have run one for several years now and my truck actually gets better gas milage than what ford's rating is for my truck. It has pulled everything that i have tried to pull without struggle. ex: one time my brother was backing our 16 foot boat down a steep hill and he jack knifed the boat trailer.. his f-150 is 2wd and a 5spd not to mention that his back tires were off of the pavement and in some grass. so as you may be assuming by now his tires were spinning. (faggot open differentials) i told him to put it into neutral and i just pulled him right out. not a bit of stuggle for the truck. now yall may be able to do the same thing with your stock intake, but you can't claim that my K&N is hurting my performance/economy. I don't really belive that a K&n will give you what they claim, but i like mine. Just like why does someone go and put a 6 inch lift on their truck and some big tires and go and sink it in the mud.... because they freakin want to. Yall have a good one.

Exactly.

If people want to put these intakes on, theres no need to shout them down, and this site obviously seems to take at the very least an attitude of indifference, if not outright endorsement to intake modification:

It's k0nda crude (MS paint FTW!) but best I could do in my search for a "correct" installation:

http://i843.photobucket.com/albums/zz359/knightfall46/coldair.jpg?t=1277223101

It's not any colder, but it IS shielded from engine heat and it IS smoother flowing, which is really the only achievement. Just thought I'd throw that out there since it's sorta hard to articulate without a picture. Most K&N kits I've seen online DO come with this shield, as do all the kits I've seen installed on "Powerblock" on Spike. Only one walkthrough on this site with a cobbled install depicts this heat shield, which makes a whole CORNER of the space under your hood the "airbox" in effect. And I will freely admit I haven't gotten that far myself, but I do intend to:

I just need to fab something up that won't look like crud and will serve its purpose.

Just curious, would having the part that attaches to the intake manifold disconnected and blocked effect the overall temp at all?

Which part? There is not much you can disconnect and block that wouldn't affect the engine runability.

The part what comes from the airbox to the core support that draws the air has a little offshoot that goes to the exhaust manifold ( for cold starts I'm assuming, but I live in California so its not necessary), would blocking that off (it would be removed, but block they opening) help the seal or temp at all.

Lord help me the stupid earlier in this thread hurts! I came across this thread looking for a "cold air" intake for my 93 Ford Ranger 4.0 OHV. I know it's old but I just can't resist.

I'll give it to them they did make some valid points. The K&N setups aren't actually "cold air" intakes. I imagine this term was used for marketing sometime back and just stuck. Unless you're running an intercooler you're not actually getting an appreciably cooler air flow.

That being said these trucks do not come with a cold air intake! They get half of their intake from the exhaust manifold. Who the hell thinks that is cold air?

Let's establish why "cold" air is a good thing for a second. Colder air is denser then warmer air, so you get more O2 per cubic inch of intake.

Unless you have a virtually sealed of engine compartment the air just outside of the engine compartment is of little difference in temperature than the air rushing through your engine compartment while you're going 50+mph. I'd be willing to bet that you won't see a 5 degree difference in the air intake from cold air intakes one with the "correct" box around the cone and one without.

So how do these intake kits provide the gains that they claim (I'm not supporting their claims in full.)? They provide a higher flow rate into the intake. Someone hit on this earlier, but down played it's significance. I believe it was because of the ample flow rate the stock box provides with it 2x4 opening. WTH??? Who here really thinks that is not a restrictive system? Doubling the flow rate is much more important than seeing a 25 degree difference in air intake let alone a less than 20 degree difference.

The "cold air" intakes are worth it when you have restrictive systems like my truck does or you're heavily modified. And yes sometimes its also worth it if horsepower gain is worth it to you in your build. Even is it equates to 1hp = $100.

Rant over. Thank you for your time.

Thanks for posting this. It made me realize I left something out of my rant above.

If your exhaust is your choke point in the system, no intake mod is going to do anything for you. I'd highly suggest doing headers before or during the intake upgrade.

They only draw air past the exhaust manifold during warmup if the system is functioning properly. ;)

The really impressive factory headers are the ones used on the early 2.3liter Aerostars.. they weren't a "shorty" header they weren't merely a long-tube either, they were a long-tube Tri-Y header....

As a note on reality...something as heavy as an Aerostar with only an EFI2.3 Lima engine needs every but of help it can get...

Some early "Fox" mustangs came from the factory with "shorty headers as well.

So did the 1992 F-150 "Lightning"


For the record the 1993 4.0 OHV engine in my '87 Supercab wears a set of Borla headers.

I can't say for certain that they do a whole lot, but they certainly don't hurt.
