2004 base spark plug tubes
Hello, I have purchased a 2004 base Boxster a few months ago. I'm slowly doing maintenance on it. Just replaced the spark plugs. I had purchased the tubes also and anticipated changing those also. I didn't need them. There is a metal tube that looks to be integral with the head/valve cover. My question; Do I have a end of year, or early 2005 engine that has an updated design, or what? Thanks for your time in helping me to understand this. Tom
