The correct parts for a 2020-22 250 or 350 EXCF/XCFW/FE/FE-S .  Bottom to top increase and the booster plug and high pressure fuel regulator are the best choice for added fueling for these parts and the Australian / European spec bike.  Only use the fuel prigrammer kit, if you need to make the bike a lot richer on top, like for wide open beach racing.   This end cap has no spark arrestor.  If you want a spark arrestor, it's easiest to add it seperatley.
