You'll get basically 3 different recommendations: NGK 3303s, NGK 6097s, and little 'ol me saying NGK BKR7EVX11s. Run the first two and change them about every oil change. Run the last one and change them about every 20K+ miles if you want to go that long. I ran the BKRs at BPU and they performed flawlessly from idle to redline and at any boost level the stock twins ever saw. Based upon my own experience, I don't see why anyone would run anything else at BPU.....
