Review on PRIME LINE Powersports 72 5006 Replaces 420956123 by Keegan Herbert

Although the part number matches I would NOT recommend this filter for a 2018 Sea Doo Spark 900 HO. The filter should fit snugly and snugly against the filter cap, which is then screwed onto the filter reservoir. On my 2018 Sparks it moves freely from side to side. If you look at this filter, it doesn't look like a Rotax filter at all. To top it off when I went to the Sea Doo dealer the OEM Rotax filter cost less than this one!
