    Any 16-psi that you like. Stant brand is usually a safe bet, haven't had any issues with MotoRad either.

    I use a regular lev-r-vent Stant cap. Easier & safer to vent off pressure if things go wrong

    I also use a Stant cap. Perfect fit and no leaks.

    I'm still using original caps. Go figure.
