The sharing of some vehicle repair and maintenance cases is updated irregularly. Let more people understand some tips in daily car use, maintenance, and testing. Use cars to understand cars better!
Porsche Kaman is the fourth largest car series launched by Porsche after the 911, Boxster and Cayenne. An entry-level two-door hardtop sports car with a mid-engine rear wheel drive.
The 14-year-old Porsche Cayman has driven 5W kilometers so far, and today is a spark plug replacement job.
I just found out that the picture says Cayenne. If there’s nothing to do, let’s give it an X and change it.
This Kaman car is 5W kilometers for spark plug replacement. Let’s take a look at how to replace the Karman spark plug with a mid-engine rear-wheel drive!
The removal of the tire is not random, but is necessary. Karman’s rear wheel drive of the mid-mounted engine causes the spark plug to be located at the rear of the vehicle. The tire can be removed before replacing it.
At this angle, you can see where the ignition coils are. There are 3 ignition coils at the rear of the left and right rear tires and a total of 6 spark plugs are replaced.
When I started dismantling, it became more difficult to remove due to the angle problem. Does it feel a little tall?
The tool you use-the universal joint socket allows you to save time and effort at work.
The electric plate of the spark plug ignites through repeated and continuous power generation to ignite the mixture in the cylinder. At this time, other parts of the ignition system generate timed high-voltage electric pulses to form a spark and generate explosion to provide the energy needed for engine power output.
Spark plug is a device that ignites the mixture of gasoline and air that enters the engine for combustion. It works under harsh conditions of high temperature and high pressure. It is one of the vulnerable parts of gasoline engines. It plays a very important role in the operation of the engine. The role has a lot to do with whether the car is fuel efficient and whether it runs smoothly.

The gap between the spark plug electrodes has a great impact on the work of the spark plug. If the gap is too small, the spark will be weak and leakage will easily occur due to the generation of carbon deposits; if the gap is too large, the required breakdown voltage will increase, the engine will not be easy to start, and at high speed “misfire” phenomenon is prone to occur, so the spark plug gap should be appropriate. The general spark plug gap used in battery ignition systems is 0708mm, and the individual spark plug gap can reach more than 10 mm.
Urgent replacement
After replacing the right side, remove the three ignition coils on the left side and unscrew the spark plugs for replacement.
The final step is to install the tire after replacing the spark plug, and use the torque wrench to confirm the completion of the construction.
