Step By Step Instructions
1. Disconnect the negative terminal from your battery before starting any work on your car’s engine. This is an important safety precaution that must not be overlooked!
2. Remove any dirt or debris from around each of the four spark plug wells using compressed air or a brush. Make sure there is nothing obstructing access to each one before proceeding further.
3 .Using a ratchet set and socket wrench, unscrew each individual plug slowly until it comes free from its well – take care not to strip or damage any threads while doing this!
4 .Once all four spark plugs have been removed from their wells, inspect them carefully for any signs of wear or damage – if they appear worn out then it’s time to replace them!
5 .Using a gap gauge tool, measure each new plug’s gap according to manufacturer specifications (usually around 0.044 inches). Adjust accordingly if necessary using only small amounts at once – too much force could damage or distort the metal surfaces!
6 .Apply a generous amount of anti-seize lubricant onto each new plug’s threads before screwing them into their respective wells – this helps prevent corrosion over time which would otherwise reduce performance significantly!
7 .Tighten all four new plugs into their respective wells using only hand pressure; avoid using too much force as this could cause damage or strip threads from either side!
8 .Once all four new sparks are securely tightened into place reconnect your battery’s negative terminal before starting up your engine again – take care not do drive away without giving it enough time warm up first though!
9 .Finally check that everything is working correctly by taking the car out for a test drive; listen out for any unusual sounds coming from under hood while doing so – if all seems fine then congratulations you’ve successfully replaced all four sparks in your 2014 Mercedes C250 model!

Why Replace Spark Plugs?
Spark plugs are essential components of any engine, as they create the spark that ignites the fuel and air mixture inside your engine’s cylinders. If your spark plugs become worn or contaminated, they can cause several problems with your engine’s performance, including reduced fuel efficiency, poor acceleration, and misfires.

Additionally, you will need four new spark plugs that are designed for this model year (NGK BKR6E-11).
Once you have all of the necessary tools and parts together, start by opening up the hood of your car and locating the spark plug wells on each cylinder head. Each well should be labeled with a number corresponding to its respective cylinder (1-4).
Once you have located each well, use your socket wrench set to remove each spark plug one at a time. Be sure to use a good amount of pressure when tightening or loosening each plug to ensure that they are properly secured in place once you have installed them back into their respective wells.
Now that all of the old plugs have been removed from their wells, take out one new plug at a time and insert it into its respective well using the same socket wrench set you used before. Be sure to tighten each plug securely so that it does not become loose while in use. Finally, replace any other components such as ignition coils or wiring harnesses if applicable before closing up the hood and starting up your car again.
