These Champion Double Platinum Power spark plugs have platinum on both the center and ground electrodes for longer life with minimal wear. The center electrode is platinum fine wire that is riveted onto the nickel alloy center electrode, and the ground electrode has a pad welded to the surface. The Champion Double Platinum Power spark plugs use a fine-wire and V-trimmed center electrode to create a sharper spark focus than conventional plugs. With their exclusive Heat-Active alloy, they are designed to reach operating temperatures quickly and maintain stable temperatures under varying engine loads. Widely designed for distributorless ignition systems, these Champion Double Platinum Power spark plugs can maximize fuel efficiency and spark energy.

Champion 7989 Spark Plugs

Summit RacingSummit Racing Verified Purchase

If you are looking at these plugs then you no doubt have a Ford 3v engine and have discovered that the factory Motorcraft plugs are a two-piece, pressed together design failure that breaks off in your engine leaving you with a nightmare situation to deal with. I broke 4 of the 8 in my Mustang. No problem, the extractor tool works well ( don't waste time or money on the glue in porcelain extractor-does not work). Anyway, these plugs are the only One-piece design I could find other then the E3's. Champion has been making plugs for a long time so are more trusted in my opinion. The one piece design should have been used by Ford but was not, leaving use with the issue at hand. My engine had 48,000mi on it and broke 4 on removal. I rated ease of install at 5 because that is for the install, not the removal of the old ones, which is a real pain. The Champion plugs work. 5,000 miles later, no issues at all, and will not break off in the engine the next time I change them. Use Nickel Anti-Seize compound on the smooth extension part only (not the threads) and you will have no problems. Bottom line,get these in your engine now and you will avoid more problems down the road, maybe even avoid having to remove the head to fix the plug issue. ...read more
