See full version: Can you hand tighten spark plugs
Overtightening the plugs will not cause any kind of driveability problem, unless you used a lot of side-load force on it and cracked the porcelain, which is very difficult to do, especially with a spark plug socket and it’s rubber insert. more
As for the coils, they only need to be changed when they fail so it can be a big waste of money to change them when changing the plugs. If you want to have the car inspected, consider YourMechanic, as a certified mechanic can come to your home or office to fully check it out before you go on your road trip.
Introduction. Changing spark plugs takes about an hour (for a four-cylinder engine) and will save you at least a hundred bucks in labor if you do it yourself. In most cases it’s a simple job that will help to maintain peak performance and the highest possible gas mileage. [links]
It can result in incomplete combustion and damage to the catalytic converter of the car. Faulty spark plugs can cause the car to exhibit starting troubles. Worn out plugs does not produce sufficient sparks, which is needed for starting the engine. This results in the engine to stall and fail to start quickly. [links]
It is a preferred grease for automotive ignition applications because ignition systems use rubber boots to keep the spark plugs and spark plug wires away from moisture Silicone dielectric grease is used on the bottom of the inside of the ignition coil boot where the spark plug meets the ignition coil.

Similarly, should you put dielectric grease on spark plugs? [links]
NGK does not recommend the application of lubricant such as copper grease to spark plug threads as the result is a reduction of frictional forces at the thread faces. This will render the torque readings inaccurate and over tightening could occur by up to 20 percent!
Additionally, should I use anti seize on NGK Spark Plugs? NGK spark plugs are installed at the factory dry, without the use of anti-seize. Anti-seize compound can act as a lubricant altering torque values up to 20 percent, increasing the risk of spark plug thread breakage.
How do you use anti seize lubricant on spark plugs? [links]
When applying it to Spark Plugs use it sparingly and only apply to the middle threads of the plug. Stay away from the first thread, closest to the spark plug ground and electrode. You do not want any anti-seize on the ground or electrode, ever! Do not apply a lot.
Using a torque wrench with dry spark plug threads is critical to preventing spark plug damage.
That’s when spark plug manufacturers and carmakers started recommending the application of a small dab of anti-seize on spark plug threads. That way, the spark plug could be removed easily the next time. more
If you ignore this advice and apply anti-seize, you must reduce the torque setting on your torque wrench by 25%. If you don’t, you’ll over-torque the plug and damage it.
