Just a little money saving info for you people getting ready to install a fresh set of plugs.

This could be off topic, but...

I used to drag race small block chevrolets... I ran a high piston dome and it would close the plug gap unless I made sure the gap was facing down. I used to mark a box of plugs along the electrode and screw them into each cylinder to find ones that lined up correctly. Is this what you're talking about when you say degreeing?

I'm curious as to why you would do this on a G35...

 

My goal is to have all of the open side's of the plugs open to the exhaust valves.
I want the flame front to start at the exhaust valve and move to the intake valve.
Thu very small, Should help in reversion, and the possibility of being able to run more timing. It is a way of very fine tuning. The SBC sure were easier to degree in.
I did notice that my factory plugs all had different readings on them, and the ones with the open gap to the intake valves were way on the lean side. This could be a big tuning opportunity. We will see soon when im finished with a few other mod's. Pasta

 

Interesting... Thanks for the answer... I hope it works out!
