K&N Air Intake

[skinz]

Will a K&N Air Intake help my gas milleage? If so any idea how much? thanks SKINZ

 

[bmxking5]

it should, as long as you don't have a lead foot. IDK by how much though.

To really get a mileage boost, you should do a cat back also.

Good luck....

Keep in mind an open-element has the biggest potential of a mileage increase.

It's funny you bring up this topic of K&N Filters husky... I went to my mechanic and talked about more engine mods that I'm going to do to my car like a possible new intake and upgraded Flowmaster, but my mechanic said that I should "remove" my K&N Filter because of how it will ultimately cause me to fail the dreaded smog/emissions test out here in California. I then asked him about intakes and filters to other trucks as well and he said that while it is okay to have them for a short while, the other trucks/cars as well would not pass the smog/emissions test after a while. So all in while, while my filter has been awesome to me, I might have to remove it because of what my trusty mechanic has informed me now :\ What are you're thoughts husky and everyone else?

Sir, your mechanic is a moron. K&N is CARB approved and will not keep you from passing a smog test in any state.

Can someone help me to understand how a K&N can help with better fuel economy?

As I understand things, the K&N allows more air flow due to being a less restrictive medium for the air to pass through. Now to me, this would be helpful at wide open throttle as more air coming in means more fuel can be burned, therefore more power will be made compared to a stock air filter.

Looking at this from the other direction, if you are at cruising speed, your vehicle burns X amount of fuel. As long as the air filter isn't so restrictive that it prevents you from reaching cruising speed, I don't see how the filter can effect your fuel economy.

Does my reasoning make sense?

Yes, that's right. Don't expect much of an increase though. Maybe 1mpg if your driving stays the same.
