2003 Ford Expedition Ignition Coil Packs

If you own a 2003 Ford Expedition, you have either replaced a coil pack, or you will be replacing one soon. This is just a weak point in these SUVs. You may also know how much these coil packs cost at your neighborhood auto parts store or dealer if you have visited one recently. Spending $500 or more on new ignition coils is simply just too much money to be spending on this job. These can be found for a lot less, and that is exactly why we are here. Our high quality ignition coils are priced a lot lower than what you"d expect from any local store. It is common to deal with a bad coil pack for your 2003 Ford Expedition.

We recommend using a thin coat on the inside of the bottom of the rubber boot. Many people will pack the boots with too much dielectric grease which can cause issues.
