Improved Racing makes a really nice one but its a pricey.
I had mine on a thermostat switch and manual switch so I could turn it on after making a couple hits when my pressure would drop slightly.
My preussre would bounce right back after turning on the fan for a couple minutes so I was happy, I intend on doing the same to my current car next spring.
This is very similar to the kit I used, had the cooler mounted under the passenger floorboard with a small fan, worked really well.
Some 5th gen guys use Improved Racing oil cooler stat/adaptor and run lines to a heat exchanger. I have one of those adaptors here sitting on a shelf.

Is this really a problem with those who are running gasoline fuels?
I didn't run one on my old car but I wouldn't usually turn the oil cooler on until I'd made a few hits or before pulling into the garage to cool the oil down a little before shut down.
I also changed the oil twice a year because it was cheap so I'm not sure if I'd ever see anything wrong.

id take 250* oil over 130 all day everyday
200-220 is mint
the most wear happens at low oil temps before it gets to temps
there is a reason they went away from the air core on the c6 zo6/gs and went to a water core
the faster you get to temp the better
I just wasn’t happy with the recovery I saw without a cooler, you would push over 260 on a hot day if you tried repeated full hit with a very slow recovery
now with the current setup, 200* thermo pellet and fan on at 210 it works great
Always sits 200-210 unless I make a hit, on a full half mile pull from 210 to 235, then quickly back to

they struggles to get to temp at all if ever unless tracked

the water cooler is the best option if the room regardless because it is an exchanger……. It brings the oil temp up much quicker than it would normally vs no cooler period …. That is the biggest benefit of them, not the cooling
This is mine with the thermostat and you can still see how much slower oil warm up is vs coolant, with the water heat exchanger they would almost pair
always try to get the most rows possible as opposed to longer rows
This will get the highest flow area and the least amount of pressure drop, with the oil volume we move it is a factor for sure
also keep in mind that as normally configured we send 100% of oil through the cooler, this is contributing to pressure drop on the system
we don’t need to send all the oil to the cooler, even say 50% is plenty to control temps and at the same time minimize pressure drop, and allowing smaller easier to package plumbing to the cooler
i modified my thermostat block to do this
