Re: 5.4 V8 coil pack recommendation?
ACCEL coils have a very failure rate (as do Grantreli). Same with most parts-store brands, which the exception of NAPA Echlin, except those cost as much or more than the OEMs.
I tried DENSO when I did my last tune-up, since they were 1/2 the cost. So far so good. Its been about 20,000 miles so far. RockAuto says they have not had a single warranty claim for them, and DENSO does produce some of the Motorcraft-branded coil packs for this application.
