Plug Gap!

[LightningXR6T]

This has been covered before, but I have 3 questions on this topic!

Q1: Why do the plugs need to be regapped?

Q2: What is the recommended gap?

Q3: What plug type/brand?

I believe that OE is Iridium, but it was said to me that Iridium plugs are useless and that NGK copper cored plugs are far superior. Iridium $25 each NGK copper $3 each. What do you suggest and why?

* To stop the spark from being blown out with higher boost applications

* About 0.9

* Iridium for sure. Keep the originals they are pretty good. I had the NGK copper ones and I changed back to the typhoon iridium ones. The copper ones gave me a bad idle even with trying various gap sizes. Although closing the gap will give you a worse idle anyway.
