I'd just put these on. $12. I install gobs of Omnispark wires. No issues here. No reason to spend any more $$ than that. $50 wire sets last just as long..... they just cost more. Even if they don't, you can put 4 sets on before you spent more. If you get 5 years out of one set...... you can do the math.
