On 2 different sets the spark plug boots split and caused misfires. The boots were 135's and they split right at the bend on the inside. This was on our SBF combo. Never had this happened with Ultra 40's or MSD wires. Now we use MSD hemi wires as once bit twice shy. I was discussing wires with Jeremy at BAE. There was a well known TAD owner in on the conversation. That guy told me to use any wire but Firecore. He said they had issues that went away when they switched brands. I guess anything can happen with any brand but we won't try them again.
Same thing happened to me.. Boots are cheap IMO..
Went with MSD, who I hate as a company.. But I like their wires and distributors..
Boots are cheap IMO..
