K&N air filters allow more air to flow into the engine. This easier breathing does save gas, as well as, giving more horsepower.

It reduces the amount of restriction in the intake passage over a stock filter. The K&N filter is a cotton material saturated with a very stick oil which traps dirt particles. It works great if cleaned and re-oiled regularly (every 3k miles). Once dirt particles are trapped a K&N filter flows less air than a conventional filter with the same amount of mileage. Another downside to the K&N filter is that if not serviced regularly it will pass dirt causing permanent engine damage.

Listen to these idiots.
We Otto re-introduce their head to their face because they are talking out their a*s.
The answer is very simple.
If you own a car with a carburetor, yes it will save a little fuel because you will have more air getting pulled down. If the air flow is restricted the carburetor will pull down more fuel.
If you have a newer car with fuel injection, it wont save you a dime. Do you honestly think if you have free flowing air that your fuel injectors will inject less fuel, common now, it is all controlled by computer.
The reason these Co's can get away with miss-leading you is because their statements are true if you own a 1980 or older V8 such as I do.
Unfortunately I don't save fuel with my filter because I don't seem to understand the word "COAST". Neither would you with a 455 Trans Am

depending upon the conventional air filter you are using yes and no...
A good clean and fairly new conventional will flow slightly less than the K&N but is usually not too much more (K&Ns claim to fame is more horsepower as more air causes the fuel system to richen itself up to compensate and allows for a little more air than normal).. however the K&Ns can allow more trash into the system as it relies on the oil to help with the filtering and most who do use them do not know how to and wind up causing more problems in the end as it requires maintainace just like everything else (Just cause it says 50 k miles doesn't mean under your circumstances as I've seen them plug just as bad as a conventional at 20 k miles do to where people are driving)
But for fuel economy, A good new clean conventional (name brand, not that crap they push at jiffy lube which does the most restrictions of the bunch) should do about as well as the k&n
and replace that fuel filter too

yes but is not that much, the really advantage is that the filters of that type can be reusable for about a year when you clean the filter as they recommend you to do it, but in the gas issue is not that much, about a 2 or 5 percent

Mine did because it lets more Air in because factory filters restrict air flow.

no it doesn't
Those guys are full of sh**...stock filters do not restrict air flow... Idiots
OMG with gas mileage being a top selling point do you really think auto companies would restrict air flow for no reason... K&N is just trying to get your money man fu** those as*holes

I used a K&N filter for a while - didn't notice any significant improvement in gas mileage myself.
