Review on πŸ”₯ Motorcraft Platinum SP546 (SP515) HT15 Spark Plugs - Set of 8 for Ford 5.4L - Genuine OEM by Brian Warmack

Revainrating 1 out of 5

Installed June 2019, faulty spark plug caused #7 misfires through April 2020

My truck was misfiring badly. I figured for SURE it couldn't be the spark plugs I installed just last summer. After taking the time to look for other possible sources of trouble, I swallowed my pride and checked the spark plugs. I knew #7 had misfired, so I checked it out first and saw carnage. The grounding hood over the electrode is completely gone. Hope the engine is ok! I pulled and inspected two other plugs on the same bank and they have flooding. All three plugs show rust/corrosion caused by a separation between the ceramic insulator and the metal body. God knows how much water got into my engine because of those unnecessary spark plugs. I want to upload a photo of these POS plugs.

Pros
  • Spark plugs
Cons
  • Safety
