I intended to respond, it's just taken a few days!
  It was I who wrote in the Lancair Network News a couple of years
ago that a Fram PH3506 oil filter will fit Lycoming four cylinder engines
"as is" and in particular, is small enough to permit installation and
removal on the Lancair. Furthermore, this filter was designed for a
late-1970's General Motors 301 CID V-8 engine. Both I and Don George (my
engine rebuilder) consider that it will handle the four cylinder Lycoming
oil pressure and flow rate. Don ran my IO-320 on his test stand for two
hours with this filter installed with no problem. I've flown with this model
filter exclusively for 85 hours. During my initial hours of flying, engine
oil pressure occasionally exceeded 99 psi (until I installed a throttle in
my oil cooler air flow to raise the oil temp above 180 degrees). I would,
however, use only the Fram and not another manufacturer's.
  As for "what if" concerns that anyone could raise,  I could sit
around and worry "what if.." and I'd never fly my Lancair.
