it depends on how many coils are bad. pep boys auto parts lists them @ $301.99 each, for your vehicle, there will be a bit of a markup on the cost of the part, that is normal.
then there is the labor, job should take between 1/2 to 1 1/2 hours x labor per hour.
when I had mine replaced only the ones that needed to be replaced were done.
I took this from another site:
An ignition coil is a compact electrical transformer that boosts the 12-volt current from the battery into the high voltage (15,000-20,000 volts or more) needed to start a car. Typically there is one ignition coil for each spark plug, either sitting on top of each spark plug (eliminating the need for spark plug wires) or physically connected together as a coil pack that is installed and replaced as a single unit. Symptoms of a bad coil pack include misfires, poor fuel consumption or loss of power -- although these can be caused by other factors.
- An ignition coil typically costs $70-$375 or more depending on the make and model of vehicle, if it is a single coil or a coil pack, and whether the part is made by the vehicle manufacturer (called OEM parts, and typically more expensive) or an aftermarket product from a company other than the vehicle manufacturer.
- For example, AutoZone offers an aftermarket ignition coil for a 2008 Ford Focus for $103; FordParts.com offers ignition coils for the same vehicle for $72-$159. Replacing an ignition coil can be a relatively straightforward do-it-yourself project. AutoMD provides how-to instructions , and estimates it as a moderately complex project that takes about an hour.
- Professional installation typically takes 0.5-1.5 hours, depending on the vehicle, at $50-$120 an hour (depending on whether the work is done at an independent or chain repair shop, or at a dealership, which is typically more expensive). This brings total costs to $100-$550 or more.
- For example, RepairPal.com estimates replacing a single ignition coil on a 2008 Ford Focus costs about $37-$49 for labor and $123-$144 for parts, making a total cost of about $160-$193; for a 2008 Dodge Ram 1500 truck the estimate is about $102-$135 for labor and $74-$120 parts, or $176-$255 total; for a 2008 Toyota Camry it's $74-$98 labor and $102-$210 parts, with a total of $176-$308.
