Champion (7989) Double Platinum Spark Plug, Pack of 1

Used these to replace the OEM plugs on 2005 and 2007 Ford F-150's. If you've been paying attention, you know most of them need to be replaced, BEFORE they get too old (IE: "carboned" up). These are a much improved design over the OEM version. Seem to work great, so far, after about a year and 30,000+/- miles. Maybe slightly better gas mileage... A little expensive, but we think it was worth it to eliminate a VERY expensive and difficult future problem of broken off plugs.

I bought these for a 2006 Mustang GT to combat the well know "spark plug breaks off in head" issue. When I tried to remove the factory plugs (about two years ago) I broke several of them and had quite the panic filled day getting them out. I decided to replace them with these when I removed the factory-style plugs recently to reapply anti-seize. My car runs just fine with these and hopefully I won't have to worry about breaking them ever again. I put a bit of anti-seize on for good measure.

As for getting the OEM plugs out, get some Kroil or PB Blaster and add lots of patience and they should come out relatively trouble-free. When I removed the factory-style plugs (which I had put anti-seize on) to put these in, they came out extremely easily with some Kroil.

The product itself is fine. I purchased eight spark plugs, when I opened the shipping box I noticed they had come out of the packaging and bounced all over the place in the box, there was no packing paper, bubble-wrap or peanuts. Three out of the eight plugs had completely closed the gap on the electrodes, they were beat up pretty good. I set the gap, and went ahead and installed them. They are working. I would be a little apprehensive about purchasing anything else if this is the common practice for packaging and shipping.
