Computers will adjust the air fuel ratios unless the filter is plugged to the point it can't. Altitude can lower horse power if it can't get enough air. If you have a chip it will increase horsepower but if it has restrictions or not enough air it will produce less

If the engine needs more air because of a restriction in the air plumbing a less restrictive filter and housing will provide more power. If the engine doesn't need it the results will be nothing.

That's why you open them up, So that they can take in more air: so that you can also,add more fuel, and make more power!:

As stated before, cooler intake temperature makes a theoretical efficiency gain but it’s so minor for a few degrees that you’ll never notice it or be able to measure while driving. A lot of claims are driven by marketing, not reality.
Effectively making it run rich.
As usual, thank you.

What I thought too. Chance makes a valid argument. The only way to test this bird is to fly it.

Spend the next weekend available a NASCAR race inside the track with your RV; I bet you can find some folks with experience for your (our) cutaway E450. I have a 2019 RC25, 26' with a 4:11 rear end, I have plenty of power.

Modern fuel injection engines compensate for atmospheric pressure and temperature. Running in the closed loop the computer will keep the fuel air ratio at optimum for the engine. Any restriction in the intake or exhaust systems will automatically be compensated for. Only in open loop operation (wot) will the restrictions cause power losses.

One of the fastest ways to add more airflow, horsepower, and throttle response to your car while still protecting the engine is with a cold air intake. The way an engine works is by taking in air, mixing it with fuel, and combusting the air/fuel mixture, which then sends power to the crankshaft and onto the transmission. The more fuel you can add to the mixture, the more power you can make, to a point. But if you just add fuel without increasing the amount of air in the cylinder, you will run the engine rich and lose power. That is where the cold air intake comes into play.




Cold air intakes are also called cool air intakes and performance air intakes. They typically consist of a type of plastic or metal tube, a heat shield or air box, and a filter. The way they help your engine is by providing a larger, less restrictive airflow path to the engine. By allowing the engine to intake more air, the vehicle’s computer can add more fuel, resulting in a more explosive mixture, thereby making more power.

Jesus man. A 4:11? She must wind up going down the highway.

Can you go into 'open loop' a little more please? I'm hoping to decrease turbulence and increase air flow. From the (valuable as usual) feed back I've gotten, it may be a zero sum game.

Even if I make air less turbulent and pack it against the intake, the computer will see that through the MAF and squelch it.

Weigh in. I always appreciate your opinion on things and thank you for this one once more. Looking forward to your response. You and Chance really need to hook up. You're both really on the ball.
