Cold Air

[Chains]

Ok, i know this is the Ranger forum, but I know that Bronco 2s are a lot alike so i just have a few questions to ask about cold air intakes.

first off on my intake box(stock one) theres two cables that go to other engine parts, so what are those and what happens to them if i get a new intake?

second i have a friend that has an fipk kandn cold air setup on his regular size bronco and i was wondering just what the difference is between getting one like he has and putting it on my bronco 2, like is it bad to get a big one or a small one??? or does the tube just have to fit?

more questions i have are:
whats the best way to mount it, like take away the stock tube or what?
what about the old parts from the intake, what do you need to do to get them out? anything special?

if anyone can think of anything else or anything that can help me out it would be greatly appreciated.thanks!

by the way i have a 90 bronco 2 2.9L v6 if that helps with anything

if you buy the kit designed for your truck, the instructions will answer all these questions!!!

but my point is that there is no kit made by anyone for my bronco 2.
so i need any help or suggestions.

I hear of people using intakes from neons. The two hoses you're referring to are vacuum lines. You'll eliminate the heated intake system off of the passenger exhaust manifold by chaning intake setup. This keeps your throttle body from freezing in very cold weather.

When you create something like that, you have to think of ways that it's going to benefit the engine, in most cases people make it worse by sucking in hot air from under the hood. Or leaving vacuum leaks open. You have to sort of know what you're doing, but the consept is dead simple. It's not going to be an out of the box solution. The 2.9L was around from 86-92, so not a whole lot of people are going to make parts for it. Though, it is a very powerful little engine given the money. I've modified one with a big cam and mass air flow with positive results.

Ford already has a cold air intake setup on your bronco II. The air box is also sufficient for a V8. I think the biggest difference you'll get is the way it sounds, maybe a little less bottom end, gain slightly on top end. I cannot think of or seen any "bolt on" modifications that really gain a whole lot of power. Only way to get great increases is to start modifing the engine internally.

well im just trying to find something cool to do thats easy and cheap, and i know that air intake is a pretty cheap upgrade, but psychopete if you know anything i can do give me some suggestions. i know little about cars and i wanna learn how to do stuff and i just need suggestions and directions.
thanks for any more help.

and about the lines i thought they were the MAS cuz thats what i saw on another site, but if i'm totally wrong then tell me. and couldnt i just take the sensor on the air box from the stock intake and drill a hole in the line to the engine and place it there? if that makes any sense at all?

-thanks again

What do you want to do with the engine? Do you want a cammed out screamer, or just a little more performance out of the engine? The rear-end gearing also makes a huge difference in take off and top speed.

A lot of people have trouble determining weather their engine is speed density or MAF (MAS). Unless you have california emissions (I've not known of anyone besides myself) Ranger, you will not have a mass air sensor. MAF is very common on most engines. It's a lot cleaner for emissions, it's actually sort of an emission device. You have a MAP ECC which uses the intake manifold pressure to help determine the air fuel mixture. This set up is bad for performance, I swapped to the 1990 california emission ECC in my 1988 that was once speed density. I had a custom cam ground that was too big for the stock computer to cope with.

The best way you can tell if you have MAF is the MAS will actually be inline of the intake hose from the air box to the upper intake manifold. Your MAP is location on the firewall, passenger side. Some MAP is used in forced induction, but the stock MAP cannot tolerate the reverse vacuum. In that case, you would need to get an after market computer that would need to be programmed.

ok so.........new idea what if i get a new cone filter or whatever and build a better box for the intake thats closed and then get some of the sensor what ever things that attatch to it and thenput that on there, dont know if that makes any sense. if it does and wont work just tell
thanks
