Junk: Terrible performance

Through TRIAL and error, I found that this spark plug set is just junk. The performance was terrible and caused my engine to misfire. The only positive thing was that they were easy to install. Don't waste your money or risk damaging your engine with these unreliable spark plugs..

Pros
  • Long lasting performance due to platinum construction
Cons
  • Higher price point compared to traditional copper spark plugs

These plugs are TERRIBLE! I replaced them after 22

These plugs are TERRIBLE! I replaced them at 22,602 miles (and should have replaced them many miles earlier). I've had misfires with the Autolite AP5144, a very rough engine when I open the throttle and terrible mileage. My F-150 ran perfect IMMEDIATELY as soon as I switched to Motorcraft forks.

Pros
  • Price
Cons
  • There are nuances
