Gap is good...I personally would go with the NGK TR-6's ... one step colder & you can buy them at NAPA for $2 each....

I have to disagree about the NGK Tr6 copper plug, there fine if your on a budget and there not one step colder than the MotorCraft SP-471, the SP-471 is the plug that comes OEM on the Ford GT Super Car, there double Platinum, I run them on MY Cobra at 23 plus pounds of boost without any glitches, on Race fuel and them some, I have also been deep in the 10"s since the first time out with the Whipple, my IRS with level 5"s plus axles and completely stock suspension and without Ricer Crap in My Ride, just a little FYI

TR-6's One step colder then a stock OEM factory plug on a '03-04 Cobra (that was my only point)...That's fine if he wants to run the SP-471 plug...Most tuners recommend the TR-6's, good plug at a excellent price ... Bottom line, put in what you want, keep the gap around 0.030" to 0.032" and go have fun!
