I have a 07 chrysler aspen 5.7 with the hemi. I want to change the spark plugs. I have the NGK 2313 Iridium Spark Plugs. Do these come pre gapped from ngk or do i have to gap them?

I was told different things from different people just want some more input.

Thank you

 

they come from ngk .044

 

I would check them anyway just to be sure. Only takes a few minutes.

 

Thanks checked them there good. I did not get a chance to change them yet. Theback one by the master cylinder looks hard. Any ideas on a ez way to get to it.Or any ideas at all



Thank you

 

Actually, the passenger side rear one was harder then that one by the master cylinder when I just did mine a feww weeks ago. Just have a good selection of different size socket extensions is the best advice I can give you. I was switching out between about 4 different extensions I have that range from a few inches up to about 4 inches. Also, if you take the coil pack off of the plugs in front of the one you are working on in the back, it makes it a little easier to get to that back one. Good luck.
