2 different types of spark plugs???
Proud owner of 2 W208 chassis ('03 CLK430 and '02 CLK55amg, both cab), and 1st time posting.
The AMG had a cyl 6 misfiring and the MBZ mec told to replace the pair of wire and definitely all 16 plugs; I purchased them ( Bosch OEM Spark Plug # 0242230500 / FR8DPP33+) from AMZN.
I went to p/u the car and mec told me that "the plugs were not the same. 10 of EXACTLY what you ordered came in a sealed box but the other 6 were different but in the right box." Clearly they were switched (by mistake) while being packed.
My ??? is: will this affect the car negatively? or should I correct the situation immediately?
I should add that the misfiring is gone so far and the MBZ mec said not to worry about it.
Experience has proven that sometimes the Community knows best, by experience!!
