FYI: Granatelli Motor Sports has recently released (Nov 08) a new coil pack and spark plug wire sets for late model (SOHC) 4.0L Rangers (etc). The coil pack is one of their ProSeries, 60k (that's 60,000 volts!). The wires, called by MPG Plus are, GET THIS: 0 (zero) ohms, WITH NO RFI! With all other HIPO wires that I know of, to get zero ohms you will disrupt your OBD II system as well as your stereo; or you get RFI with "near" zero ohms. The coil covers '05 thru '09 4.0's, but the wires go way back. For you guys with '04 and earlier 4.0s, look to a site called "Performance Distributors," for their Screamin Demon Coil pack. It is rated at 45k, and goes back to '90 models. Lastly, BBK tells me they are developing a new throttle body for late model 4.0 Rangers (the mustang's TB is different), and is due out late this summer. A local national drag racer (does NOT want his name given due to endorsement contracts, but runs NHRA Pro Stock) says to use the newest "open design" sparks plugs with these coils (Bosch IR Fusion, EA-3, etc) as the open spark does a much better job of fuel ignition, if you have a strong enough coil and wires. LUCK!
