Message:
got rid of the autolight 3923 plugs. Put in specified autolight 5224 platinum.

Gas mileage went up by 2 MPG and the engine doesn't die when I put in park, it used to die sometimes. It's got pick up and idles nice.

IMO the 3923 ain't that great IMO

Interesting. I guess Harlow is cool, since it's still the ex-Ford brand. I didn't feel like a hassle the first plug change on my '01 4.7, so I went with the OEM Champions. Smooth sailing so far at 47K. I used Bosch platinums virtually the entire life of my '92 5.2, 217K mi.,always ran great. Anyone tried Bosch +2 or +4 in their 4.7? Hey, D-C is German, too. Good matchup?

The myth of 3932's is grdually beng exposed. All those bullsh1t claims about smoother running and more power are coming undone.

Fukcing ignorant trailer park hill billies.

Don't think it's really a myth that the 3923's give better performance. I've talked to a few people who get better performance in their 3.9L Dakotas, but most with the 4.7L say they work okay (just like Demon Dakota).

In the 3.9L, the 3923s are a lower temperature plug. For the same effect in a 4.7L, try 5223.

I have 5224 platinum in mine. Original spark plugs were almost completely finished at 30k miles when I had them replaced.

It might be that lower temp thermostat and lower temp plugs = engine runs colder so PCM gives more gas = better low end acceleration, which is what the kids want.

Actually, the colder plugs made the pinging stop in my 3.9. I tried the stock equivalents, then I tried platinum, then I went to the 3923 and the ping went away.

the 3923 are only for the 3.9/5.2/5.9 engines. the 4.7 typically does not benefit from them. I tried them and liked them once but every 8k I had to re-gap them... then went to Bosch +4's and they worked great for 45k miles...
