I put this in today (96 4.0 GEMs). About $26 for two hoses from AutohausAZ, $4 pcv valve from O'Riellys. Even though my oil baffle was very clean after about 12k miles. The AutohausAZ hoses are a bit better quality than the previous Roverparts items, and cost less.

Best 4x4 PCV modification

 

Yeah the previous owner of my 97 XD changed that hose before I bought it. I agree it's a much better quality hose vs the OEM. I've got about 4k on the PCV Mod and it's doing great. Just a quick and easy thing to upgrade on a GEMS engine setup for sure.
