I was changing plugs on a 4.7lt Grand Cherokee today with customer supplied parts - the 4.7 takes 16 plugs and uses a different plug for the intake side and the exhaust side. Customer supplied a set of NGK's for the intake and a set of Champions 
for the exhaust side. This is a shot of the oem Bosch plug I pulled out and the new Champion plug - the difference in the threads between the two plugs was a bit shocking to say the least. You can feel the rough threads on the plug as you are installing them - oem plugs only for this guy!
