i havent changed the plugs myself yet on my truck. my last vehicle was a camaro and that was a B#tch to change the plugs on. the front 4 cyl were easy to get to but there was no way to fit a ratchet down and get the rear 4 without a jack.

 

Compared to most modern vehicles I have seen , the 4.2 is easy.
Plan on about 30 mins to an hour.

 

Changed the plugs plus installed new wires in less than an hour. No lifting of engine, no hard reaching. Easy job.

awesome thanks for the replies

 

That was the only reason I picked the 4.2 over the 4.6L V8. I could do the work myself.

 

I like to lift my truck up and remove the tires and go through the wheel wells, instead of going in from the top.
