what is the best spark plug did i can use on my 2007 charger SRT

 

Just the regular NGK Platinum plugs, not the double platinum or iridium plugs. I installed them in my old truck 2007 dodge ram Hemi, they worked awesome, the engine ran so smooth, I wondered myself why did Dodge used the crappy champions copper plugs from factory, you'll notice too when the engine is first run in the morning, there is a slight shake to the engine. With the NGK plugs, the slight shake is eliminated, it will run so much smoother than it was new. Trust me.

 

thanks bro

 

Everything I've read about the platinum plugs says that they run too hot for the Hemi. This can cause damage to the coils. Is this not true?
