total newb here. looking to change my spark plugs. anyone have any advice or helpful pics???

 

use google videos, its all the same basic idea, for an I6 there on the left side of the block.

REMEMBER do not mix your wires up from the distributor, do one plug at a time
and keep track of were each plug wire goes, or else you got another issue

 

Go slow make sure there in even and don't over tighten

 

this is a spark plug.....LOL

 

thank you sooo much. hopefully ill get it all done tomorrow

 

HAHAHA good starting point.

 

Sorry I couldn't help myself...LOL

 

Plain copper Champions work fine for the 4.0....and they're cheap.

Be sure they are gapped properly (don't assume gap is right out of the box) and
do NOT overtighten. Use a torque wrench if you haven't done much of this work.

 

My friend recommends NGK but I as i've seen from most of the articles that i've read,champion plugs have good feed backs. I'm quite confused since my friend knows a lot about automotive stuffs but I found out that champion plugs is best for 4.0 when I did my own research. I'll be replacing my plugs this weekend. Also,I want to ask if i could rely on this general instruction video that i've found from auto repair manuals?(it's for sedan) I can't find a video for replacing spark plugs for cherokee.
