Default How do you change the spark plugs? 4.7

So I bought a new set of platnum plugs & popped the hood today to put them in.

How the heck do you change the plugs? Looks like there was a tiny coil or some other electronic thing on top of them.

I hate the idea of paying someone to do this - but I also don't want to have to replace a bunch of coils because I started hacking.

yeah its pretty easy. just take off the nut holding the black coil on there. and pull up, theres a bit of suction so pull up hard. then take your spark plug socket and take the old one out. unplug the connector too.

As a heads up, our trucks tend to prefer the autolites (according to the people on this forum). I have the NGKs that match the model number on the sticker under my hood.

I love how easy it is to change plugs on this truck. They are all easy to get to and simple. It really can't get any easier.

You are going to want some extensions and ujoints on your socket. There are some awkward ones in the rear of the motor.

Thanks guys - I didn't get to it today. I will for sure get to it tomorrow. I have more than enough tools - just getting old & losing patience.

I can't even change the oil on my wife's volvo. To get to her plugs you have to remove have the intake!
