The build quality is near identical if not better than my original valve, which was so gummed up I decided to just change it. Design is completely identical, and functions the same as the Mopar one. Noticed a slight performance increase changing the dirty valve out, but upon further investigation I need to do a full EGR valve and line clean out/replacement in order to fix my truck's issue. If your PCV valve is gummed up I highly advise looking into your EGR as well. If you're worried about issues of using a non Mopar part, you can be sure that this part is identical in function to the original and will not cause any problems. Be sure that you get it lined up and that it threads in correctly. The valve will seat fully down into the hole and the two little bumps will sit at the stops around the mounting hole. Does take some effort to remove the old unit and install the new one. It's recommended to carefully check for air leaks once the new unit is installed. Also, a little bit of motor oil on the o-rings may be a good idea for seating, but I did not choose to do this myself.
