I can't seem to find the information I'm looking for on this, but I have a 2g with a greddy RS bov and K&N intake. It has the atmospheric dump on the bov. And someone put an oil cap and taped around it on the intake. I bought it this way but and I don't like the capped off intake but that's just how I am, my question is what are the pros and cons of doing this and does it really benefit anything?
