Changing the BOV is pretty straight forward. Just unscrew the hose clamps, take the old bov off, put new on on, tighten hose clamps. But one thing about those BOV's, not sure if you are aware of this yet or not, but when running a BOV that vents to atmosphere you will encounter drivability issues. The reason for this is because the BOV will vent air that has been accounted for by the mass airflow sensor, which can cause some stalling issues. So you will want to get one that recirculates air. I believe that HKS sells a recirculation kit for their SSQV. Forge makes a couple of nice BOV as well that are set up to recirculate.
