Hey zdriver I see on your parts list that you have the same bosch plugs I have. How do you like them? I think they helped out a ton. I just know next time some one other than me will be installing them. Those fucking plugs took me 6 hrs to install. I would like to talk with the dumb fuck that designed this setup. I mean seriously I started laughing hysterically when I got them installed and thought to myself I wonder about the header install. Hey well give me a call I got zome questions. My name is ken and my cell is 813-927-9294 and home is 813-759-6583.
