1024, Big Suckers come with a K&N filter and yes they can be cleaned. Just purchase a K&N filter charger kit and follow the instructions. They can be purchased at just about any bike shop or auto parts store.
Since you already have the screamin eagle air package you can replace the filter with a Bob Woods filter.The screamin eagle flows 135 CFM and woods has them up to 325 CFM.I installed a 325 filter on my 95" TC which vastly improved the fuel curve in the mid to upper rpm range.
