    Yeh .. after watching Brock's 30+ minute youtube dyno  session , almost no gain with hi flow filter alone , and 2 or 3 hp with full full system and dyno tune. So yeh hardly worth it .. first time ive been wrong bought anything , lol.
    I  just purchased my z900 couple days ago. 2018 model with 12000k on it. .. Good bike ..Cool site .. Thx for the info.

    Full system and a tune are worth it, beyond that thereís no point unless you start modifying the airbox to allow more air in. Thereís a thread on here about the airbox mod if youíre interested, though I believe itís better for top end than midrange, so itís not something Iím fussed about doing.

    Moore mafia did a video (youtube) where he tuned a Z with the link pipe. Same customer went back after changing for a full system and had the bike tuned again. The aftermarket headers gave a bit more top end and the link pipe was slightly better in the midrange.

     If filter "A" has the same surface area as filter "B" but filter "B" flows more air than "A" then filter "B" is also letting more particulates through that's unavoidable.
      For every pro there is at least one con, that's life.
      For some an extra 0.3 bhp is worth the cons.

     K&N pro's :+0.3 bhp, reusable, free sticker.

     K&N con's: initial purchase price, reduced filtration, cost of cleaning fluid and oil, risk of over oiling, significant additional time for a filter service.

     
    Tighten it 'til it strips then back it off half a turn.
