Great plugs, really helped smooth out the engine.


Worked great and the old 2008 edge engine feels like new again!


They had about 50,000 miles on them when pulled and looked like they only had about 10k.


You will have to gap each plug to your car and engine's specs, or expect nasty idle and performance.
