Well, I assume you would have noticed the car not boosting past 10 and concluded that was the problem at the track. IMO, wires are wires. As long as they deliver spark, they are good enough. I would do a boost leak test to fix the new leak but I do not think that was your problem at the track if you could boost to 20 psi. Usually with a boost leak you will knock. If I were getting 1 count of knock, I would have upped the boost more. 1=0. Might want to check the plug gap or replace the plugs as maintenece.
