Sixity Auto 8 pc DG508 48688 Curved Boot Ignition Coil Pack Compatible with Ford F150 F250 E150 E250 Mustang Crown Victoria Expedition Explorer 4.6L 5.4L V8 Lincoln Mercury for DG457 DG472 DG491

I am very happy that I purchased these ignition COP’s (coil over plug) from Sixity, instead of the numerous other brands on Amazon. Along with new spark plugs, my engine runs better than it has for years.I saved a considerable amount of money purchasing these from Sixity instead of OEM.I was nervous about buying COP’s on Amazon. But I knew Sixity was a good aftermarket brand. My worries were immediately gone when I started my engine.

The vehicle has more power than it ever has, the parts exceeded my expectations

I have owned (7) Triton 4.6 or 5.4 motors so I have gone thru a few coils. For a price point of about $4.38 each, I was skeptical to try these. I was really surprised at how well they are built. They installed dead on ( only used two), mounting hole and insert were done correctly, and the connector clipped right into place. Remember to put a dab of die-electric grease on them since they do not come with any applied. The boot was soft and a little thinner than most other ones I have used. I did take a star off since the spring is about 3/8ths inch shy of the bottom of the boot. Not sure why they did this since the OEM ones and several other brands have the spring right to the bottom of the boot. Truck fired right up and runs smooth. We'll have to see what the longevity of these will be. If I have any premature issues I'll be sure to come back with an "edit".

Fixed cylinder 6 misfire in my 2007 mercury grand marquis. 20 minute install. 7 more if any of the others go bad.

They have already started to fail one by one. Don’t waste your money.

Worked just as well as the ones costing $300 a set

This is a vine review so take that into consideration.You absolutely can not beat the price of these. There is a problem with the springs so use your oldones. I threw two of these on a 2008 crown victoria police interceptor and they ran perfect.They are still going after a few thousand miles. So they work just use the original springs.Seriously if you want to save money and/or have spares just in case these are a great set to have.
