I have a 1998 Dodge Neon R / T and I need to replace the engine part that the spark plug right in. I was told its cylinder head, but I’m not sure if I got the right answer. I had pulled out a problem with one of my spark plugs out of the threads, and the temporary solution, because it was back to “Part Name” with a threaded adapter. I was told that I have to change the next time my opinion or spark plugs and I have the same problem happen again (which is starting to happen), please substitute the correct way to resolve this problem would b 2, the whole “part name “. What is the average cost and time to replace this part? The do not ask for how much the part costs. Thanks.
