Great for the cost
I’ve had these plugs and coil packs in my two valve 5.4 Triton engine now for a year and they are holding up great. Amazon really saved me a lot of money as apposed to going to an auto parts store.

I have mixed feelings on this
Coil packs, The price you cannot beat.. However don't throw away your old ones too quick because 1 or 2 of the 8 may short out within a few weeks or they may not... Mine did.

Solved Engine Misfire Problem
My 2003 F-150 5.4 Triton displayed Service Engine Soon light. Use of code reader resulted in two codes 1) P0316 - Engine Misfire Detected on Startup (1st 1000 Revs) and 2) P0306 - Cylinder 6 Misfire Detected. Replacement of the spark plug and the coil for cylinder 6 fixed the problem.

Defective coils
I installed this set as a precautionary step for maintaining my engine for break downs. I drove about 2 days on this set and had a misfire on #4 cylinder and barely got home with the misfiring and lack of power. I suspect the coil on that cylinder is defective as they are not oem coils but the plugs that come in the set are. And just an FYI I didn't have any issues on the engine prior when the original parts were installed. just doing preventive maintenance on the truck.
