The K&N filters are "up there" in quality.
But I'm not sure you fully understand why they said to change the airbox.
Maybe you do, but for those that don't..
Think of it like a huge air conditioner, with a huge compressor (engine). You have an intake "grill" that lets in a fair amount of air.. but you know that compressor can handle more air.
Now, you CAN change the filter on the intake, and perhaps some more air will reach that compressor.. but not much more.
Or.. you can take the intake off and put on a bigger one, which will allow more air to enter.
This means removing the entire intake, not just the filter or the part that holds the filter.
NOW your able to send lot's more air into that compressor.
But..that's kind of moot unless you increase the size of the output vent (pipes). Otherwise you have a bottle neck, as those pipes can only push out so much air.
And.. if you do both of those, you will need to put on some sort of fuel manager (power commander).
This is because the engine is "programmed" to expect a certain amount of air to be sucked in, and will only put X amount of fuel into the mix. You have to be able to tell the bike to add more fuel.
it's not cheap, doing all three. But it increases the horsepower a lot. Which is why people do it (that and for the looks).
The Big Baron's intake is one of the top ones. And one of the most popular. You have a ton of visual "options" to choose from with it.
