just wanted to know what is the best spark plug and gap to use on an 06 jeep grand cherokee 3.7

 

You can call any auto parts store and the can give you the gap for your jeep

 

Open the Hood if a 06 is like any 98 and under, then the spark plug gap would be on a sticker when you pop the hood. Or in the manual.

I tried looking on google but i cant find the gap, if its not in the engine compartment on a sticker then call advanced auto parts or something and ask them.

 

it should be .042 according to this site.
