Default Cold Air intake 4.0

Does a cold air intake actually help the MPG any with a 4.0 05 ranger? Is it worth the money, how about a throttle body spacer?

Well I guess that settle it... I have heard mixed review with CAI on rangers but a majority say theyre a waste.

They are not a waste if you do other mods to help it

Tuner, exhaust, headers will make it work for you better

These aren't enough. The charge is flowing too fast through the head.

Jp7 I am really looking for a couple things just to improve my MPG.... I heard that on the silverada the CAI gives on average 2mpg increase but it looks like it doesn't do much for a 4.0 ranger. What reccomend to bump my mpg up a little? What about a programmer are they any good?

MPG is so important to manufactures because of a thing called CAFE. If there was a silver bullet part that improved mileage by 2mpg than it would be included stock.

If you have the ability to advance your timing without causing knock each internal explosion will cause more ooomph into the piston making better mileage. Factory-tuned means "tuned for the worst possible engine made during engine development" to make sure even on a bad engine it won't cause problems. This is the same reason why I can gain ~35hp on a car that has stock hardware.

That being said, keep your driving habbits mild and your truck in peak working condition. I recently bought a 2.3 and found it to be getting only about 21mpg. I did extensive work to get it back to "like new" operating performance, and also found the Right rear parking brake was grabbing. I now get 24.7 with the same truck.

HI!... Well I have tested CAI's on the dyno. Most work some do not. I gained 11RWH.P with one on my F-150, 5.4L, but if you look at the air intake on a stock F-150 it is VERY restrictive. Also picked up 19RWH.P by getting rid of the clutch fan and switching to dual 16" electric fans (F-150). Never dynoed the one I built for my 07 Ranger. But when I added a CAI, electric fan, and a ASP under driven crank pulley I picked up over 5MPG. Last trip I went on I was getting 27MPG in my 4.0L ranger. This is on a basically level highway at 105KPH the whole way. The small mods do work. My truck is perfect proof of that. It went 15.98E.T completely bone stock. Then I added the above mods plus a ported TB and the EGR mod and it went 14.68E.T. The engineers do not design these things perfectly, not even close. Actually what I have been told by buddies that work in the DYNO room here in town at Ford's is that they design restrictions on certain aspects of the engine to bring H.P/TQ down, restrictive intake tracs, intake manifolds, TB's, PCM tuning, cam profiles.

I built my own CAI. Cost me like $5 due to I had material in my garage from other projects. Works very well, has a cleanable filter. I did testing years ago on several different vehicles. People call after market CAI's "HOT AIR" intakes. While this is true while the vehicle is sitting idling it's NOT true while the vehicle is moving. A sheilded CAI is better than a CAI that the filter is out in the open. We installed digital temp sensors under the hoods of several vehicles right next to the CAI's. When the vehicle was moving at roads speeds the temperature under the hood was only 5-7 degree's warmer than the ambient temp outside. This is do to the outside air coming through all the openings in the front of the vehicle. The under hood temps only climbed when the vehicle was left idling still or at stop lights but quickly dropped once the vehicle was moving again.

On my 07 Ranger I opened up behind the Passenger's side headlight where the filter set-up is located. I have a built aluminum box that surrounds this opening. My filter is located in the box. At the dragstrip I remove the head light assembly so the filter gets a direct flow of fresh air. Testing with and without the headlight has yielded a 1-2 tenth drop in 1/4 mile times with the headlight out.

Here is a 4.0, actually lost power due to a cone filter intake.

Question

That data is not included.

The only reason the AFR would change during an open loop pull would be if the flow past the maf was measured incorrectly due to flow characteristics caused by the new intake geometry.

HI!... Well I've seen on the F-150's that the A/F's need to be adjusted after the installation of a CAI due to it running leaner. Especially on the new F-150's due to them having a "scubber" inside the intake trac. A after market CAI will cause it to run one full point leaner. Seen this on many other vehicles also. Once the A/F's are correct back to where they were before the CAI, we always see a H.P/TQ increase. Even if it's a minimal increase we always see a increase, never a loss.

I notice by your dyno graph that the CAI did increase peak H.P and extended the power band. I bet a tune to correct A/F's would match if not better the stock #'s.
