very stupid question but what do these do? and what are the benfits of these mods? thanks

The EGR block off plate will prevent the hot exhaust gasses from recirculating back into your engine, and the PCV re-route will help keep oil and sludge out of your intercooler, and the fingerstick will block any codes you may get from blocking off the egr, or adding an aftermarket exhaust.

Here are some links on the egr removal, and pcv reroute.
