WITCH PARK PLUG FOR A 440 CUDA

[THE ZUKE]

Hello guys 

Today I have been working on my CUDA, I needed to remove 4 spark plug because of the steering original box (On an other topic  ).

I think it's a good idea to change all of them, actually there are NGK-R VRS V-POWER.

Could you help me to do the good choice 

Are the NGK a good product, witch brand and model do you use ?

Thanks for the advices.

I've always had good performance from Champion RJ12YC for a stock to mildly modified 440.

Thank you 303 MOPAR, could you tell me what size of key to disassemble the spark plug do you use, 16 or 21mm ? Currently I have to use 16m

I have always had problems with NGK just quitting & refusing to fire again , far from my favorite so I also recommend the Champions or Autolite
They use a 21 mm / 13/16 socket
