hey guys dont wait for spark plug change 04-08!!
I just completed the plug and c.o.p change on my 2007 Lincoln mark Lt and it was fairly easy and made a huge difference in power and fuel economy. My truck had just over 63k on it and the electrodes were getting short on the plugs and the coils were cracked at the top just asking water to get in them. I was very fortunate for this site and all of you guys wisdom on the spark plug issues. I didn't have any break and honestly none of them were super tight. Thanks guys and dont put it off till its too late. Brian
