depends on mounting area and cooling supplied to TFI, some of family's Ranger TFI's only lasted 1-2 years

How to improove TFI cooling. May be to add a little fan?
Truly, I wanna purchaise Ranger '02-03, may be this year, may be next. As I can see, new OBD-II trucks have distributor-less ignition with dual spark coils. Is this system more reliable? The other quation, old good russian wolga more then 10 years ago was with MAP, nowdays all the wolgas are with MAF. And owners of them claim, thet they never replaced MAP, but they have to replace bad MAF every 3-5 year (depending on make, usually Russian MAF, Bosch ore GM). Is it problem for Ford?
About my star, hall-effect sensor, TPS and ISC were replaced ones! All the other sensors and actuators, including O2 are still alive! I have more then 400 K on clock, she was born in '89/.

move to area in outside air flow such as front of radiator away from engine heat
see prior post w link
MAF's are fragile things, like Russian ballerinas, heating and sensing filaments and skinny legs broken easily, not emotionally strong
MAP's are tough, not much to fail
MAF's respond faster to air flow changes
many systems now are COP coil on plug ig. systems, more to fail but must faster spark rise time and energy due to no hi voltage resistant wire
Rangers are tough and easy to work on, room under the hood...get a 2002 or newer, less OHC follower failures...and of course the manual tranny

COP is a good innovation, but if coils are not made in one block for every side of engine (3 ore 4 coils in block), when I worked for GM dealer, I remember, how we had to replace all the ignition block if one coil was bad! For $150! Nissan, Lada prefere to use separate coils for every plug.
