looking for any and all info.pertaining to upgrading older diesels to meet t4 specs. jd-cat- cummins
we`re not dealing with trucks. const equiptIt was tried on road trucks here in California and all I heard was horror stories with retrofit diesel filters. I don't know of any that worked right. The owners ended up selling out of them and getting into real T4 equivalent trucks. It is so many years since the T4 switch I would think this market would be drying up anyway but maybe somebody is still doing it.
that was my first thought. we may have to lease some stuffI think before you spend too much time checking regs and installers, check the price.
