So my question is what plugs should I be running for APR stage 2? On APR’s website it recommends to run NGK R7437-9. If you look at older posts I think APR use to recommend series 8 but now saying 9. But I also found this posted on the VWVortex forum last year (Feb. 28 2017) by an APR employee. A little confused.
We use the NGK R7437 9 for Stage 3 and racing applications. You can use the 8's at stage 1 / 2 for street applications.
I daily drive my car and maybe 2 or 3 track days a year.
So which plugs?
1. NGK R7437-8
2. NGK R7437-9
3. R7 plugs
Thank you
