Tom,
So after that educational tidbit is it better to buy the one filter
relocation kit model from Moss or the two filter model?
In addition, what is your thought on an oil cooler kit? Are they
worth it? Do they even work and is there a driving difference with an oil
cooler kit? Let hear your thoughts?

Those with M2s (NB) and considering an oil filter relocation kit might want
to look at this one:

One or two, it up to you. Since MANY Miatas make it well past the 200K mark
with stock filters, I seems to me the only reason to go remote is ease of
changes. Ease of filter change is something that varies with each kit and
is subjective at best.

In addition, adding a remote kit does add other failure points to the
system. Hoses can bust, fittings can leak, and the oft forgotten o-ring
between the adapter and engine block can fail as well.

As far as oil coolers go, yes they do work. Do you need one? It depends.
How hot is your oil? Hot oil loses viscosity and therefore wear increases
on engine parts. Cold oil is thicker, increase drag, and can cause increase
wear on engine parts. In addition, oil needs to run at least around the
200F mark. If is stays too cold, contaminants (gas/water) are not boiled
off, and the viscosity is decreased.

This one is a little easier. If your oil is too hot, you need an oil
cooler. If it's not, you shouldn't install one.

Usually dual filter setups are in parallel, not series. So they actually
reduce the pressure drop across the filter and therefore the load on the oil
pump, as well as increasing the oil volume by another 1/2 quart or so.

Filtration effectiveness is a function of the pore size in the filter and is
not affected by the number of filters (either in series or parallel).
Sometimes series systems use a finer filter for the second element, which
does increase effectiveness, but this is usually done on hydraulic systems
where different pore size filters are available.

Dual filters in theory allow longer life since each filter is only seeing
half the volume. In practice, what really happens is that the filters
actually WORK twice as long as a normal setup. Automotive filters have a
bypass valve that opens when the pressure drop across the filter gets too
large (filter becomes clogged). There is some evidence that this occurs
before a 3000 mile oil change. Therefore, by using dual filters, you are
actually filtering the oil all the time between changes.

Ward, I would only add an oil cooler in if you drive long distance or the car is modded and you race the car regularly.
