Best TJ Replacement Spark Plugs To Use????

I am driving a 1999 Jeep TJ Sport, 4.0L, 5 Speed, 120,000 Miles. What is my best option for replacement plugs, rotor & cap.

I'm a fan of the O.E. champion or NGK plugs in the stock heat ranges. Adding Platnum to them doesn't change much. Standard Brand makes excellent Cap & Rotors, look for Brass in these products as it makes a better spark & last longer. Remember to add a very small amout of anti-seize to the spark plug threads when installing them and die-electric grease to the top of the plugs after they are installed to help seal between the plug & the plug wire. You'll not see these steps done in many shops because of the extra time it takes, but you will thank me the next time you change the plugs. Also, grip the plug wires at there end and twist when removing them.
