Yeah, hopefully I don't run into any problems. The plugs that I pulled out were worn down from age but looked (I know that means nothing) like the same style as the ones I installed. They were AGSF-32F I beleive... Either way, hopefully my car won't have any issues... it didn't before, the new plugs I just put in are the same if not better... and I can trust that they are all gapped correctly and the same since I did it myself. We'll see as time goes on. Thank you all for the help though, I appreciate it.
