It's so easy. I just replaced mine for the third time on Saturday. I use NGK Laser Platinums #PFR5G-11. They come already gapped correctly. $10 each at Advance Auto. The Denso IK16's have an ultra fine 0.4mm electrode that only lasts about 30K miles. The plats will go for 100K, but I change mine at 50K 'cuz it's so cheap 'n easy.
The ones out in the open take about two minutes each to change. The #5 on the pass side takes just a little longer. The #6 is the only tough one, but not too bad. This is how I get at #6. I use 1/2" drive, which is my way. I have the 1/2" plug socket, then a reducer from 1/2" to 3/8", then a 3/8" universal joint, then about a 3" extension. I wrap duct tape around the joints so the whole thing stays together. Ya don't wanna leave anything down there outta sight. That brings it up just above the tube for a 3/8" rachet.
It's really a very easy job.
