Review on Champion 7989 Spark Plug - Double Platinum Power, Carton of 1 by Telly Roden

Revainrating 1 out of 5

Excellent solid spark plugs for Ford Expedition

This is a great fork that will not "break apart" on its own like the Motorcraft factory forks did. In general they hold up well. A few notes on preparation/caution. These plugs are "thicker" than the original plugs and require a 5/8" socket for installation and removal (compared to the 9/16" sockets on the original). I also had a weird problem with the connector losing the electrode after 13,000 miles! I over revved at higher RPMs but idled fine. The tip of the cork hit the ceramic at higher RPM and didn't trigger.

Pros
  • Double Platinum Power - premium spark plug. Stronger performance.
Cons
  • Upgrades available
