  • Twin Air - Air Filter

    Anonymous in TN

    Best Yet

    Tried most out there, best air filter for my Honda 450L. OEM was just too restrictive and bike runs significantly better with the TA air filter. Read some review about dirt that got through. Not mine, it's clean. Trick is to stretch TA over the filter cage enough that it just lines up and goes in quick. If you have to readust and have trouble lining up the filter bolt, its not seated in the cage right. You will also need a longer air filter bolt, I bought the TA one. I use Fab1 air filter oil and am a happy camper. Keep another one ready to go for a quick swap out when the time is right.

    Fits 2021 YZ450FX

    Just installed on a 2021 YZ450FX! Install was a breeze everything matched up perfect! Bike feels like it’s runs a little smoother and a little less noise from the air box! You need to change this on your website so it says it will fit the YZ450FX not just the F.

    Great Product

    Good quality at a cheap price. Because they are cheaper I don't feel bad about replacing them more often.
