Can someone explain the purpose of upgrading to the RS7 sparks? I know noob question but I want a clear answer.

pretty much once tuned your stock plugs no longer like you so gotta replace them

For every 75-100 crank HP, you should run a step colder plug. Here's the recommendation from NGK:

Since even a stage 1 gives that to us, it's a definite need at stage 2 levels where we add that much to the wheels lol

And yes, the M revision is the new one, so if you go into the dealership, just make sure the part number you give them ends in an M.. or they'll look it up and probably see it has a new superceded part number
Just changed out the OE plugs for the RS7's today. Car idles so much smoother now!!! Running "M" revisions.
Word of caution/advice: just because they are supposed to be pregapped from the factory doesn't mean they are. I went to Harbor Freight and bought a set of feeler gauges to check the gap on the RS7 plugs and I had the following gaps right out of the box: 0.024", 0.028", 0.028-0.030", & 0.026". I re-gapped them all to 0.024" before installing them.
OE plugs looked very good considering I just turned over 9900 miles. I checked the gap on these as well and found they had the following: 0.024", 0.028", 0.030", & 0.025". I'm assuming that the 0.028" and 0.030" gapped plugs were the source of the rough idle.

I ordered mine from ECS. At 25psi my stock plugs were having the spark blown out, the RS7 plugs have been champs.

RS7 stock gap or GTI stock gap? I believe GTI is .028 and RS7 is .025

Thanks that's what I meant the stock plug just making sure mine were good when I swapped out my own plugs with new ones.
