Spark plugs, what's the best method?

Outside of the recommended brands. What is the best method for R&R? What torque specs are you using? What tools to gap? Anti-seize? Dielectric? Best buys on the coil packs and wires?

Gap with feeler gauges, the twist disc damages the harder plugs, so pliers or a tool made for the task is best.
.027 to .030 gap.

Ruthenium plugs are almost required for a tuned car.

Denso coils are the only ones to get. Others have tried the Accel brand with poor results.

These are coil-on-plug, so no wires needed.

Thanks I have feelers. Some in other car worlds have updated the wiring to the coil packs...probably overkill.

I have heard the coil packs are short lived.

I am still looking for a good how too. Looks like once you get the engine cover off you still have to remove a ton of shit.

The video that is on the JET FUEL ONLY channel is very descriptive.
Basically you remove the cover, pull a couple lines out the way, disconnect the boost tube from each side, wrestle with the bov connector and disconnect the coils, loosen the bolts and pull em out. Really not a bad task.

I use the gm dielectric grease for the boots and aluminum antisieze on the threads of the plugs.

Snug tite is good enough.
Don't use power tools. Galling threads in aluminum is a real thing.
