Thanks. I recently came across this Fluidyne oil cooler which I can
mount up out of the way from the plugs. The single flow through will
reduce oil backpressure a little.

I don't see anything in my notes about recommended filters. I would
appreciate a suggestion.

Size - 21x5.875x3.''; Dry Weight - 12lbs; Fittings -
(2) AN-12 & (2) AN-6 & (1) 3/8'' FNPT; Oil Capacity - 1.21Qts

That looks near identical in size to the 2nd gen RX7 oil cooler.
Do they have any real heat transfer data available other than
"it worked in Buba's NASCAR racer"? :)

Did find this chart on the fluidyne web site.
Therm-HxTM  Engine Oil Coolers

It is unclear the MPH speed refers to the flow through the
cooler or the speed of the car. I suspect it is the speed
of a car.

The 14 GPM spec looks marginal. The BTU chart does not match
the part numbers.

Better make sure they pressure test these things to over 200 psi.
