So if I install a cold air filter, what do I do with the IAT sensor thats now inside the factory air filter box? The sensor looks something like this:
Thanks.



And also what do I do with these 2 small air hoses on the left side of the airbox? Can I just plug them?

 

You already have a Cold Air Intake/filter, all Rangers do

But if you want to change it then put it in the new filter box.
No box?
Then it isn't a cold air intake
So put on on the tube from filter to intake, drill a hole and mount it

You understand that these types of setups: https://www.knfilters.com/cold_air_i...rd_ranger.aspx

Are not Cold air intakes(CAI) they suck air from INSIDE the engine bay, so actually reduce performance.
Independent testing shows that: The Cold Air Intake: World?s Most Popular Drop In Mod Finally Busted? | The Daily Derbi

Cold Air Intakes did work, past tense, with carbs that sucked in engine bay air, thats where CAI comes from.
With the switch to Fuel Injection all manufactures also used CAI for best performance

"They" can say it increases power because "they" can modify the tests any way "they" want.
"They" can stuff a rag in the stock intake, test it then pull the rag out and put "their" unit on, WOW 11% increase in Horse Power..............

For LOOKS these are great, but don't do it for power

Another heads up, after putting the unit on, if you can HEAR it, hear the air flow when you REV the engine, then you have restricted the air flow NOT improved it
You can NOT hear smooth air flow, you can only hear turbulance

 

Thanks.
Well I was just thinking of putting in a cone filter because I think the factory intake tube/hose is pretty restrictive, it has so many bends and turns and it is pretty narrow. So those were my thoughts. Yea I'd like to put it in a box for sure.

 

The bends and twists don't matter as long as engine can pull in enough air
Look at turbo intercoolers, loads of twists and turns on those pipes

You can install a vacuum gauge on the dash to test for restricted air flow
On a back road, level and straight, and SAFE
Get vehicle up to top speed and then floor it and watch vacuum gauge
You want to see under 2" vacuum, 1"-1.5" is optimal

Now the 3.0l Vulcan does have a smaller throttle body than optimal, there are some articles bout changing it, do some Googling
But the stock air tubes and filter setup can be used with larger throttle body
