Hey guys. I just got my 4.2 F-150 in July and im finally looking to power it up. What Intake woud be the best (Volant, Mac, k&n, or Airaid). And what exhaust do you segest? Thanks.

 

Hey I don't have either yet, I'm pretty much stuck in the same position as you...but people on FTE have recommened to me the most is MAC. You should just get an exhaust made and buy tips...its a hell of a lot more cheaper.

 

I think we need to post a big sticky that says, "POWER RECOMMENDATIONS"

MAC Intake is the cheaper and efficient route. All the other intakes are good too.

Exhaust, whatever you think. Most people tend to go towards flowmaster or gibson.

 

is Volant a good intake? what is the best?

 

I just installed my AF1 intake and it is awesome. I love the new noise coming from under the hood. The power gain is noticable. Plus....IT LOOKS GOOD.

You could go with a computer chip also. That is a quick power gain. I have a superchips flip chip and it made a huge difference.

On exhaust, magnaflow or flowmaster are the top ones for the Fords. They sound good and add some get up and go.

What Exactly does Cold Air intake do and how does it work?

 

A good cold air intake like AF1 is made of high quality stainless steel. The inside is smoothed to allow better air flow without the turbulance of the stock system.

The stock system is also very restrictive. It only allows the air coming in from between the bumper and grill surround and some other small places to get into the air box. Plus, by the time the air has made all the sharp turns and bumping into everything it has become hotter due to turbulance.

An air intake system sucks air from somewhat the same place but it is completely open. It can take air from the easiest route. Air still rushes in to the stock location but your also getting air from inside the engine compartment.

Basically, they streamline the air intake to make the air cooler. Colder air burns better and mixes better with fuel.

A Stupid Question.... so there is nothing that actually cools the air that gets suck in? is an air intake truely worth it?

 

they can be called cold air, because they can be boxed, and lead to the hole in a fender, which is cooler, or cold in comparrison to, engine air! thats it.

But yes it is worth it, because the filters and tubes are typically bigger than stock

If you have any more questions about what filter to buy, just look for yourself. We have a sticky at the top of the page that has lots of power recommendations for ya.
