Traded out the OEM spark plugs for the RS7 plugs today. Part# 079-905-626-M. These have been rather popular for people on the forums with tunes and have been performing well. We will see if they work well for me.
These are one heat range cooler than the stock plugs and should be pre-gapped to .025 which is what you want. Audi suggests replacing them every 30k on the RS7 so its a longer lasting performance plug too.
Update: Looks like there is a newer version of these plugs. Part# 06K-905-601-M
