[QUOTE="Crunchtime2k, post: 1525934, member: 38412"] After trying several ford plugs such as sp578 , sp542 and no resolve , NGK 6510’s are a winner and resolved this odd pinging at 5000rpm that would occur sometimes. Make sure to gap at 0.028 as they come out of the box at 0.041~ and be very careful with the iridium tip. No more pinging and a noticeable upper end increase in pull. [/QUOTE]
