All this speculation, so I will speculate too. If PGI has done their own thing since the start of their company, making filters their way, with excellent results. Why would they let a bankrupt company and intellectual property change how they do things now? They wouldn't. They didn't get to make all these good decisions just to bankrupt their own company with inferior designs.It will likely be in name (brand) only. The FRAM name, contrary to opinions here, is extremely valuable and well-known.
News from Greenville OH is that they have moved equipment from that plant and taken it to the IL plant. Who knows which equipment it is though.
I'm going to bet the equipment can be used to make their filters, their way. If you noticed they didn't take everything, they pick and chose what they bought to re-use.
