    Hi All
    Thinking of putting on an after market air filter. Either Piper Cross or K&N. Are there any real benefits and has anyone got either? Is it just a straight swap. I have a 2009 Sprint ST1050. Cheers. Ride safe.

    I've never bothered, but I believe the K&N ones are easier to clean. Mine is a 2009 too :)

    I never bothered and take out the flash guard on the OE ones for better airflow.
    Do not use a K&N oil filter. You put your life in danger if you do. They are prone to failure at the weld.

    I'm not sure the theoretical benefits are worth the effort. I live near the seaside, so proper air filtration is a must. Apart from that, my racer mechanic fella said they don't do much so don't waste your money. Oh, and welcome to the "club".

    A Tesco dishcloth is working very well with "Old Trophy" :cool:.

    I've read the fit of the K&N can be poor, allowing unfiltered Air in. Any filter that claims freer flow by definition must be allowing more particles through.
