Well....., had you mentioned that you have the same exact engine as Jon...., this may have possibly been more realistic to take heed of.I ordered the stock VP plug set 4-5 years ago and they sent me the NGK BPR6EFS and have been using them ever since with no issues. I previously used Champion 401 but the NGKs definitely burn cleaner. I replace my plugs every season usually around 75 hours and I have the same engine, 5.7 GSi PEFS. Hope that helps.
