Are you installing NGK Iridium LFR6A1X-11? The first time is always the hardest! Just finding out where they are, pulling back ALL the harnesses, harness brackets and hoses so you can get to the coil packs and unplugging the harness connector to each pack.

With FI, you are probably going to gap at 0.35. The plugs should be torqued to 15-21 ft-lb and the coil pack bolt 75-95 in-lb.

Again, the first attempt is the hardest.

Try to get a copy of the "Service manual" on CD. Might go to Performance Nissan and check to see if you can download. Even with that, you just need to dive in and get dirty.

Have you gotten to the point of looking and finding the coil packs? I found the drivers side easier. Remove the air intake and look for the three (3) coil packs.
