MACSBOOST exclusive! High performance oil filter for all Honda Aquatrax Watercraft (2002-2006 R12X,F12X,R12,F12) Physically longer filter allows for more internal surface area with a silicone anti-drainback valve, more pleats of finer filter media than stock. This gives you better filtration than the stock OE Honda filter! The gasket is treated with PTFE for easier installation and removal. This is the best aftermarket oil filter money can buy! Honda recommends changing the filter and oil every 50hrs or every season.
