Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Knock Retard



I've used them all (from the common to arcane) on 1.6 liter 4 bangers to the LS2 in my GTO. I've never had any problems with any plug other than Champion. All of the rest are interchangeable in my experience.

Most every plug is different. Every car is different. These cars only run good on copper core plugs when modded.

Good example...most cars blow up on a 3.2" with no mods and Bosch plugs are better found in trash cans...but I guess your a living example of beating the odds. Good job.
 
I'm honestly surprised you don't have more KR than that but the common goal is 0* of KR. I will be nice but recommend you tune, put on more mods, and or drop down some pulley sizes (ie go larger) until you achieve 0*. Any KR is bad KR! One you car will pull and perform better with 0* and two you will don't have the risk of ruining your motor.

I get where you're coming from with the airplane stuff from wwII it makes sense but all motors are different.
