2011 yz450f Air Filter help

Hey guys, I just bought a 2011 yz450f and a new no toil air filter. But am a little confused on which side goes up or down. The no toil filter is 3/4 yellow and one side is white, I think the yellow side faces down towards the engine and the white side faces up against the gas tank but not 100% sure. Hope you guys can help, thanks.

The coarse foam side goes up. White.

agree,...alway's the course side up with the denser foam on the bottom.
