What years have the Spark Plug blow out problems?

Sorry, I've searched, and haven't been able to find the answer. Anybody have any idea what years have the most trouble. Could you guys that had the problem respond with the year. Thanks.

I have an 03 5.4, and just wondered if I need to be packing parts.

97 - 02 2v 5.4 engines. Since you have an 03 model, you should have the revised heads that have more threads in the cylinder head. However, your not out of the water yet as the gen 2 Expys with the 3v heads had the two-part spark plug that is infamous for cracking upon removal due to a carbon build up on the threads. There is a special tool for aiding in removing broken spark plugs.

Just as the other two said, it was mainly with the heads that had the plugs with the fewer threads. Thankfully on my 98 4.6 with 174,000 I have no problems for I have the 8 threaded plugs.

the 03 does not have the 3V heads, that didn't start in the Expys until 05 (I think). My 04 w/5.4 still has the 2V heads.

I also have a 00 Expy 5.4L with 151K miles on it. I just got it and I have no idea when the plugs were last changed. Haven't checked the mileage yet.

I had one blow on the passenger side while towing a car trailer with a small 3500lb car on board. Pretty scary when it happens.
O2 Expedition EB with 5.4. At the time it had about 130K miles. That was about a year ago. I dont trust it for towing now just because I wonder if it will happen again.
