Just did plugs today and checked me last set and I actually was using .026. With my tune I decided to go with 0.022.

This really is a super straightforward change. Greta video and super helpful for anyone needing it, but as easy of a spark plug change as anyone could have.
I swap mine out at least every 15k and it couldnt take more than 1hr. I have my ngk 2 step colder plugs at .025 across the banks. Precisely adjusted and everything running perfectly smooth. In my experience, it is most important to install everything per torque specs and make sure your gaps are consistent across the banks. Run higher boost and drip the gap from .032(stock) to .022 I sit in the middle at 4psi boost increase and feel that .025 is a strong gap with ngk stage 2 as well as my mods. |
