Should You Replace Coil Pack with Spark plugs? (At the Same Time)

In this video I am going to explain if you need to replace your car's ignition coil packs when you change your spark plugs. I'll discuss how spark plugs and coil packs work together to power your engine, why spark plugs wear out faster, testing coil packs, rules of thumb for when to change coils, and maintenance recommendations.
What I cover in this video:
1. Do coil packs need to be changed with spark plug replacement?
2. Spark plug replacement intervals
3. Coil pack lifespan
4. Coil pack vs spark plug failure symptoms
5. Testing coil packs
6. When to replace ignition coils
7. Preventative maintenance on ignition systems
By the end you'll know whether you should automatically swap coils just because you're installing new spark plugs. I'll summarize the best practices based on parts longevity and following recommended service guidelines, not overspending on premature parts replacement.
This video is for anyone wondering if ignition coil replacement should coincide with routine spark plug changes. Applies to all gasoline engine powered vehicles - cars, trucks, SUVs, etc running on 4 stroke engines requiring plugs and coils to run properly.

I ALWAYS replace the 3 coils in the back for V6 engines, because it's hard to change the 3 spark plugs in the back. Spark plug change, e.g., for Lexus cars, typically at 100K miles are hard AND expensive. You don't want to pay for labor again to replace the back coils afterward! Save the old coils for the 3 in front, which are easy to replace; even Homer Simpson can do it!!!

I just had my spark plugs replaced. Wondered if i should do coils. Car has 135k miles on it. 2006 civic

And always use high quality plugs, like iridium. They will last around 100.000 km. And ensures a good spark and clean combustion.

I had my spark plugs replaced, the coils are burnt and should be replaced soon, I can use them for a little bit before they cause damage to the new spark plugs
