I use the HD stock replacements. I have a 95" with T-Man stage 4 heads, high lift cams and high comp. pistons and have no issues at all.

Switched to NGK Iridium IX on all my bikes several years ago.

Keep watching on EBay and you can pick them up at a decent price.

Either..same price and easily will go 20K on an FI bike.. NGK is closer unless I plan ahead.
