LS1 WK spark plugs

[Matchstick1101]

Hey everyone,
I was just wondering what spark plugs people use in their LS1s. I changed mine with ACdelco plugs 4 months ago but realised they are the wrong ones. It's unmodified and is used just for general street use.

Thanks .

I used the standard NGK BPR6EF plugs in my VX GTS from the original 5.7l to a 7.0l, and they never missed a beat. Replaced every two years.
