They do it on ebay and autotrader too.
BTW for Oil Filers, use a genuine Mazda, nothing else.
They have like a special bypass that is designed so they can have full oil press at startup.
And while on the subject, always use a Mazda thermostat as as well for the similar reasons..

Will removing my thermostat help my rotary engine run cooler or make more power?
No and No. Mazda rotaries use a bypass style thermostat. When the thermostat is closed, the water pump recirculates the same coolant back into the block without going through the radiator. This allows the engine to come up to operating temperature more quickly. Without the thermostat, the bypass is never closed, and the engine will overheat. An overheated engine makes less power, until eventually it makes no power.
Thermostats are available in 160F, 180F, and 195F ratings for rotaries. For best HP, the 160 is the best choice. For best fuel economy, 195 is usually the best choice. Mazda usually installs a 180.

Directfreak- the pics in the thread you linked "reasons for oil filters" are no longer available, but informative none the less.
Some mentioned using Mazda thermostats too. When changing a thermostat (on any vehicle) take the time to look at the old one. I had a 92 MX-3 and when I changed the thermostat, I didn't notice that the housing was slightly recessed and the thermostat plate itself was slightly egg-shaped just enough that you would notice if you weren't looking for it. I put it together, started the car, and of course, I wasn't lucky enough for it to accidently line up, so it was leaking coolant out the thermostat housing. I tried it a second time, and still didn't notice that I was supposed to spin the oblonged thermostat until the plate sat perfectly in the recessed area. Tried it a second time, and same thing. Coolant leak. Then I figured that I didn't have the thermostat housing tight enough, so I proceeded to gorilla torque the bolts, and being that the bolts were steel and the housing was aluminum, quess which one broke first? I bought a new housing from Mazda, and they told me about the recess in it, and the slightly off set shape of the thermostat plate.
Hope I saved someone some $$$ by posting my mistake. If you feel enlightened, you could send me some of that money. It will be well spent on preserving the life of another RX-7
