yes and no. The XT6E was designed originally for a paper filter, which lets through a lot more air than a foam filter. So, for the same air volume you need a physically much larger foam filter. If you do install the foam filter, you wil probably reverse the benefits of opening up the airbox; you increase resistance. Installing a foam filter is advisable if you ride a lot in dusty environments, if not, and you do not want to change your airbox to fit the larger foam filter, probably best to to keep the paper version.
Other alternative that works is K&N, however, it does not filter very well so the resistance is low and it fits in place of the air filter.
