you're going to love it. Like any BOV, inspect the donut gasket at the bottom before putting it in; also, some people use RTV gasket sealant (on the outer area of the donut gasket), which might not be a bad idea if you're concerned about leakage, although I never had a problem.

It is a good idea to make sure that each of the allen bolts that hold the "shell" onto the unit (you'll see) are tightened decently.

I can't wait to hear a dom3 on that BOV....
