[QUOTE="cj428mach, post: 15006518, member: 142081"] Like hotcobra said 9 threads would help. I dont know if anyone has any real evidence that 4 threads aren't reliable if plugs are torqued correctly. I just replaced the heads on my 03 to repair the head tick. The drivers side head was still available in March. The passenger isn't available any more. I put the new 2005 revised head on the drivers side and had a 04 head rebuilt for the passenger side. My car only has 9700 miles on it but I figured if I was pulling the motor to fix it I was going to upgrade both sides to 9 thread plugs. [/QUOTE]
