    Perfect upgrade on the grom! Absolutely love this on mine!

  • clint (verified owner)

    Looks great, just needs one sharp edge around combustion chamber smoothed out & installed.

  • Ryan

    Will this fit a 2022 monkey?

    • kevin estep

      No. As listed, it’s for the 19-21. Different engine.

  • David Fullington

    Does this need an oil cooler in the system? Is one provided? Recommended?

    • kevin estep

      Not all application will require it, but many will. It depends on the usage and environment…
