Would like to add cold air intake to my 86 Bronco II. I have only seen 1 photo of a bronco II 2.9L with one. I haven't been able to find an actual kit to add one, so my question is if anyone knows if there is a kit out there I am not finding or if it is something that needs to be fabricated. Thanks!
 
I don't think there's a kit that's made specificity for yours, but I believe they make universal kits you could try.
 
Add a cold air intake? What happened to the one Ford put on it from the factory?

Sent from the can
 
You have a factory CAI setup that for actual cold air is far better than any aftermarket setup out there.
 
Yes, Bronco II or Ranger has a factory Cold air intake, as do most vehicles, air is picked up in front of the engine so comes in at outside temp, so the coolest air possible.

Make sure the air pre-heater vacuum valve is not stuck, giving you pre-heated air 24/7.

Cold air intakes are pretty much installed to "look good" or to "sound good", there is no noticeable performance change.
Nothing wrong with that, many people install nicer wheels and don't expect to go faster :)

What heats the in coming air up is the Sun, lol.
And the engine somewhat, as an engine warms up it's heat is transferred to the metal intake manifold, this can add a few degrees to the incoming air.

Some will run a 160deg t-stat to see if they can drop normal operating temp by a few degrees, most "cold air intake" sellers recommend this because this is what actually can give you a performance boost, not the intake itself.

Cooler air is denser so more fuel can be mixed with it, must be mixed with it, since the engine can't control air flow, so cooler air = more fuel and more power.
This is why engines are "peppier" in the colder months, and why MPG drops in the colder months.

Lots of dyno tests involving cold air intakes out there to view, and if they are not the manufacturer's tests then they pretty much show there is no benefit in performance above a working factory system.

Your factory intake is a cold air intake - it draws air from behind the headlight on mine.

Putting a big cone filter under your hood that sucks up hot air from the engine compartment is NOT a cold air intake, regardless of what KNN says on their box.

If you dont like the stock one for whatever reason, make sure your custom design is actually getting COLD air, or you are just wasting money.
 
It would be cooler (pun intended) to add a snorkel.
