Review on Champion 7989 Spark Plug - Double Platinum Power, Carton of 1 by Mark Perry

Revainrating 1 out of 5

Works great on F150 V8

I bought these to replace faulty OEM two piece spark plugs that are failing on my 2005 F150 V8. They are specially designed to prevent breakage on removal and can withstand high torque as they are one piece. The dealer wanted to fit the so-called improved Motorcraft spark plugs, but I refused. After the old spark plugs were removed and replaced, the engine ran a little better. Buy, the longer you wait to change spark plugs, the more likely they are to go bad, and Ford will make you pay for the labor to use the extraction tool. At 62,000 km 4 of mine broke.

Pros
  • Maintains stable operating temperature under all engine loads
Cons
  • Annoying
