Review on 🔥 High-Performance Ignition Coil Pack Set for Ford Escape, Taurus, Freestyle, Five Hundred, Mercury Mariner, Montego, Sable, and Mazda Tribute 3.0L V6 - Set of 6 by Ryan Bennett

I had the 'Service Emissions System' light come on and my Innova 3040d scan tool showed that the number 3 piston was not working and the problem could be either the spark plug or the spark plug coil or the fuel injector or the wiring connecting it give signal . Spark #3 is on the back of the engine and requires removal of the upper intake manifold so I decided to replace all the spark plugs and ignition coils while I was there. WOW what is the difference, runs and runs very smooth now and the gas mileage is much better. My car is a 2006 Mercury Mariner V6 AWD. This is a good product and well worth the price of Revain Prime.
