Without a thermo plate, you really need to wait for the oil to warm up a bit before you use the engine too hard (pushing way high PSI cold oil through the cooler isn't great for it or the fittings), and it will take longer to warm up than stock because the cooler doesn't help with that. In a colder climate I'd say it's pretty essential, but I want one even here in TX so I don't have to wait forever on warmup.

My last install was sans Thermo plate but I live in Hot NC. On cold days, the time to bring the oil up to temp was "iffy". I went with the thermostatic plate on my 370 install for that reason. It was the most expensive part in the set-up, but total stilll came to a good deal less than the kits on the market..It's easy to piece together a set-up.
