Hi - looking to change the sparkplugs on a 2003 QC, 4.7, automatic transmission. Was wondering if any of you had any tips on the easiest wway to get at them - from the top, through the wheel well, underneath?

Thanks!

 

From up top, Remove the air box, The passenger side ones are tricky but it can be done with out removing the lines that get in the way. You just have to turn the coil packs and manuever them out. Use dialectric grease on all connections. Good luck

 

Thanks - I appreciate it. I searched a little harder and found a link to a writeup. I had not even looked and assumed they were between the exhaust manifold area like the V8s of yesteryear. MUCH easier!
